Trading Psychology Glossary — Every Term Defined (India)

Accountability Performance

The practice of answering for one's trading actions, whether to a journal, a mentor or a peer group, which raises the cost of breaking rules. External accountability strengthens discipline when internal willpower alone falls short.

Anchoring bias Bias

The tendency to rely too heavily on the first piece of information encountered, such as an entry price or a round number, when making later judgments. Anchoring to a purchase price can stop a trader from exiting a broken trade because it has not yet returned to breakeven. also: anchoring

Animal spirits Behavioral finance

Keynes's term for the instincts, emotions and confidence that drive economic and market decisions beyond cold calculation. It captures how waves of optimism and pessimism, not just fundamentals, move markets.

Anxiety Emotion

A persistent unease about uncertain outcomes that can cause over-monitoring of positions, hesitation and difficulty following a plan. In trading it is often a sign of positions sized beyond one's true risk tolerance. This is educational information, not psychological or medical advice; if distress affects your daily life, consult a qualified professional.

Availability heuristic Bias

The tendency to judge how likely something is by how easily examples come to mind, so vivid or recent events feel more probable than they are. A dramatic crash in the news can make a trader overestimate crash risk and act too defensively. also: availability bias

Base rate Decision science

The underlying frequency of an outcome in a reference class, such as the historical share of breakouts that follow through. Ignoring base rates in favour of a vivid specific story is a common error; sound decisions start from the base rate and adjust.

Base rate neglect Decision science

The mistake of ignoring how common an outcome is in general and over-relying on specific but weak evidence. A trader who believes a setup always works because of a few memorable cases is neglecting the true base rate of that pattern.

Behavioral finance Behavioral finance

The field that studies how psychology and cognitive biases cause investors and markets to depart from the fully rational behaviour assumed by classical theory. It explains phenomena such as bubbles, panics and the persistence of predictable mistakes. also: behavioural finance

Building consistency Performance

The work of making process, risk and behaviour uniform across trades so results reflect an edge rather than mood. It relies on routines, checklists and review to remove the variation that a trader introduces from day to day.

Building discipline Performance

The gradual strengthening of the ability to follow rules under pressure through routines, environment design, small wins and accountability. Discipline is treated as a trainable skill built by repetition rather than a fixed trait a trader either has or lacks.

Burnout Emotion

A state of mental and emotional exhaustion from prolonged stress and overtrading that dulls focus, motivation and decision quality. It is addressed through rest, reduced exposure and routine rather than pushing harder. This is educational information, not psychological or medical advice; if distress affects your daily life, consult a qualified professional. also: trader burnout

Calibration Decision science

The degree to which a person's stated probabilities match reality, so that events they call 70% likely happen about 70% of the time. Well-calibrated traders know how confident to be; overconfident traders are systematically miscalibrated.

Checklist Decision science

A fixed list of conditions verified before acting, used to ensure no critical step is skipped under pressure or fatigue. In trading a pre-trade checklist enforces that setup, risk and sizing criteria are all met before an order is placed. also: trading checklist

Cognitive bias Bias

A systematic error in thinking that arises from mental shortcuts, causing judgments to deviate predictably from what evidence or logic would support. In trading, biases distort how traders perceive risk, probability and their own performance. also: psychological bias

Cognitive load Decision science

The total mental effort demanded by a task, which is limited and degrades decision quality when overloaded. Too many screens, indicators and simultaneous positions raise cognitive load, so simplifying the process preserves judgment. also: mental load

Confidence Core

A justified belief in one's process built from preparation, experience and evidence of an edge, distinct from certainty about any single trade. Healthy confidence lets a trader act on a valid setup without hesitation while still respecting risk. also: trading confidence

Confidence through process Performance

The idea that durable trading confidence comes from trusting a tested, repeatable process rather than from recent wins. Grounding confidence in process keeps it stable through losing streaks and guards against the overconfidence that follows hot runs.

Confirmation bias Bias

The tendency to seek, favour and remember information that supports an existing view while discounting evidence against it. A trader in a losing position may read only bullish news, ignoring the warning signs that would justify an exit.

Consistency Core

Applying the same process, risk and rules across every trade so that results reflect an edge rather than mood or luck. Consistency turns a scattered set of decisions into a repeatable process whose expectancy can be measured and improved. also: process consistency

Continuous improvement Performance

The ongoing practice of reviewing performance, identifying weaknesses and refining the process in small, repeatable steps. It treats trading skill as a craft developed over time rather than a fixed talent, without implying any guaranteed result. also: kaizen

Contrarian Behavioral finance

An approach that deliberately trades against the prevailing crowd, buying when sentiment is fearful and selling when it is euphoric. It rests on the idea that extremes of crowd emotion often mark turning points, though acting too early against a trend is costly. also: contrarian investing

Crowd behaviour Behavioral finance

The way individuals in a market influence one another to act alike, amplifying moves as buying begets buying and selling begets selling. It is the mechanism behind herding, bubbles and panics, and it can detach prices from underlying value. also: crowd behavior, mass psychology

Daily trading routine Routine

A repeatable sequence of preparation, execution and review steps performed each trading day, from pre-market analysis to a post-market journal entry. A consistent routine reduces decision fatigue and keeps behaviour steady across sessions. also: trading routine

Decision fatigue Decision science

The deterioration in decision quality after making many choices, as willpower and attention are depleted through a session. It leads to impulsive late-day trades and skipped checks, which is why rules and routines offload decisions in advance. also: ego depletion

Decision tree Decision science

A branching map of possible actions, events and outcomes with their probabilities and payoffs, used to compare choices by expected value. It forces a trader to think through scenarios in advance rather than improvise when the market moves.

Deliberate practice Performance

Focused, structured practice on specific weaknesses with immediate feedback, the method by which experts improve. In trading it means reviewing trades, isolating a recurring error, and working on it deliberately rather than simply logging more screen time.

Discipline Core

The consistent execution of a trading plan and its rules even when fear, boredom or a losing streak argue otherwise. In practice, discipline in honouring stops and position sizing protects an account far more than the quality of any single entry. also: trading discipline, self-discipline

Disposition effect Bias

The documented tendency to sell winning positions too early to lock in a gain while holding losers too long to avoid realising a loss. It is a direct consequence of loss aversion and it systematically lowers returns.

Drawdown psychology Emotion

The emotional experience of a sustained decline in equity, which tests patience, confidence and discipline more than any single loss. Managing it means accepting drawdowns as normal, protecting mental capital and avoiding the urge to trade bigger to recover fast.

Efficient market hypothesis Behavioral finance

The theory that asset prices already reflect all available information, so consistently beating the market on public information should be very hard. Behavioural finance treats it as a useful baseline that real markets, driven by biased humans, only partly satisfy. also: EMH

Emotional decision Core

A choice driven by an immediate feeling such as fear, greed or frustration rather than by analysis or rules. Emotional decisions tend to buy tops, sell bottoms and abandon plans at the worst moments, which is why they are the central problem trading psychology addresses. also: impulsive decision

Emotional discipline Core

The practice of acting on predefined rules rather than on the feeling of the moment, especially when a position is moving against you. It is the bridge between knowing the right action and actually taking it under stress.

Emotional recovery Emotion

The process of regaining composure and objectivity after a painful loss or drawdown so that later decisions are not distorted by it. Structured routines, journaling and reduced size help a trader return to baseline rather than trade from a wounded state. also: recovery after losses

Emotional regulation Core

The set of skills used to manage the intensity of emotions such as fear and greed so they do not override a trading plan. It is not the absence of emotion but the ability to feel it and still act according to rules. also: self-regulation, emotional control

Euphoria Emotion

An intense feeling of elation and invincibility, usually after a winning streak, that leads a trader to abandon caution and oversize. Euphoria is a warning sign because it typically peaks just before overconfidence causes a large, avoidable loss.

Expected value Decision science

The probability-weighted average outcome of a decision repeated many times, found by summing each outcome multiplied by its probability. A trade with positive expected value is worth taking on average, even though any single instance can lose. also: EV, expectation

Fear Emotion

The emotional response to perceived threat that, in trading, causes hesitation, premature exits and avoidance of valid setups. Managed well it is useful caution; unmanaged it makes a trader freeze, cut winners early or refuse to take a planned trade.

Fear and greed cycle Behavioral finance

The recurring swing of market sentiment between fear, which drives selling and undervaluation, and greed, which drives buying and overvaluation. Understanding the cycle helps a trader recognise emotional extremes in the crowd rather than joining them. also: fear-greed cycle

Feedback loop Performance

A cycle in which the results of past actions inform and adjust future ones, the engine of learning in trading. A tight loop of plan, execute, review and refine turns experience into improvement, while a broken loop lets the same mistakes repeat.

FOMO Emotion

The fear of missing out that drives a trader to chase a fast-moving market after the planned entry has passed, usually at a poor price with a distant stop. Acting on FOMO abandons the risk-reward that made the setup worthwhile in the first place. also: fear of missing out

Framing effect Bias

The tendency for a choice to change depending on how it is presented, for example as a chance to gain versus a chance to lose. The same trade can feel attractive or alarming depending on whether it is framed by potential profit or potential loss. also: framing

Frustration Emotion

The irritation that builds from missed trades, choppy markets or a losing streak, which erodes patience and invites rule-breaking. Recognising frustration early is a cue to reduce size or step away before it becomes tilt.

Gambler's fallacy Bias

The mistaken belief that independent random events are due to reverse, such as expecting a win after several losses. In markets it drives traders to add to losers or increase size because a run must end, when each trade's odds are unchanged. also: gamblers fallacy

Goal setting Performance

Defining clear, mostly process-based objectives, such as following the plan on every trade, rather than fixating on profit targets one cannot control. Process goals keep motivation aligned with actions a trader can actually influence.

Greater fool theory Behavioral finance

The idea that an overpriced asset can still be profitable to buy if a greater fool will pay even more for it. It rationalises paying above value during bubbles and collapses when no further buyer appears.

Greed Emotion

The excessive desire for gain that pushes a trader to oversize, hold beyond a target, or chase risk without regard to the plan. Greed turns a good trade into a bad one by refusing to bank a reasonable profit or by adding size at the worst time.

Growth mindset Performance

Carol Dweck's concept that ability can be developed through effort and learning, as opposed to being fixed. A growth mindset lets a trader treat losses as feedback to improve rather than as verdicts on their talent.

Habit formation Routine

The process by which repeated behaviours become automatic through cue, routine and reward, reducing the willpower each action needs. Deliberately building good trading habits makes disciplined behaviour the default rather than a daily battle.

Habit loop Routine

Charles Duhigg's model of habit as a cue that triggers a routine which delivers a reward, repeated until automatic. Understanding it lets a trader replace a harmful habit, like checking positions compulsively, by keeping the cue and reward but changing the routine. also: cue-routine-reward

Habit tracking Routine

Recording whether key behaviours, such as journaling or honouring stops, were performed each day to make consistency visible and reinforce it. The simple act of tracking raises adherence by adding a small reward and a clear cue. also: habit tracker

Herd mentality Bias

The tendency to follow the actions of a larger group rather than one's own analysis, buying because others are buying and selling in a panic because others are selling. Herding fuels bubbles and crashes and often peaks just as the crowd is most wrong. also: herding, herd behaviour

Heuristic Bias

A mental shortcut or rule of thumb that lets people make fast judgments with limited information. Heuristics are efficient and often useful, but they systematically misfire in uncertain, probabilistic environments like markets, producing cognitive biases. also: mental shortcut, rule of thumb

Hindsight bias Bias

The tendency to see past events as having been predictable once the outcome is known, the sense that one knew it all along. It corrupts learning by making traders overrate their foresight and misjudge how much of a result was luck. also: knew-it-all-along effect

Hope Emotion

The wish that a losing trade will recover, which in trading becomes a liability when it replaces a stop-loss with waiting. Trading on hope keeps a trader in a broken position long after the evidence says to exit.

Illusion of control Bias

The tendency to overestimate one's ability to influence outcomes that are largely determined by chance. In trading it shows up as believing that more screen time, more indicators or more effort can control an inherently probabilistic market.

Impatience Emotion

The urge to act now rather than wait for a qualified setup, which leads to early entries, premature exits and overtrading. It is the emotional opposite of the patience that a rule-based process requires.

Implementation intention Routine

A specific if-then plan that links a situation to a predefined response, such as if price hits my stop then I exit immediately. Research shows these plans sharply increase follow-through, which makes them a powerful tool for enforcing trading rules. also: if-then plan

India VIX Behavioral finance

NSE's volatility index, derived from Nifty option prices, that reflects the market's expected volatility over the next 30 days and is widely read as a fear gauge. A spiking India VIX signals rising fear and uncertainty among participants. also: volatility index

Intuition Decision science

Fast pattern recognition built from experience that can guide expert judgment, but which is reliable only in stable, high-feedback environments. In noisy markets intuition is easily confused with impulse, so it is best used within rule-based guardrails. also: gut feel

Journal review Routine

The periodic study of accumulated journal entries to find recurring mistakes, emotional triggers and profitable patterns. It is where the raw record of a trading journal is converted into concrete lessons and process changes.

Learning plan Routine

A structured plan for what trading skills and knowledge to develop next and how, turning vague self-improvement into deliberate practice. It keeps learning focused on the weaknesses that reviews reveal rather than on random new material.

Loss aversion Bias

The well-documented tendency to feel the pain of a loss about twice as strongly as the pleasure of an equivalent gain. It makes traders cut winners early and let losers run, the exact reverse of sound risk management, unless firm rules counteract it.

Managing uncertainty Decision science

Accepting that outcomes are unknowable in advance and making decisions with odds, sizing and predefined responses rather than seeking certainty. It replaces the futile search for a sure thing with a repeatable way of acting under doubt. also: decision under uncertainty

Market bubble Behavioral finance

A period in which prices rise far above intrinsic value, driven by optimism, herding and the belief that a greater buyer will pay more. Bubbles inflate on euphoria and eventually burst, and they are far easier to identify after the fact than during. also: asset bubble, speculative bubble

Market euphoria Behavioral finance

A collective state of extreme optimism in which participants believe prices can only rise and ignore risk. Euphoria typically accompanies the late stage of a bubble and is a contrarian warning sign that sentiment has reached an unsustainable extreme.

Market sentiment Behavioral finance

The overall attitude of participants toward a market or asset, ranging from fear to greed, that can drive prices away from fundamentals. Sentiment gauges help explain why markets overshoot in both directions and why extremes often precede reversals. also: investor sentiment

Mental accounting Bias

The tendency to treat money differently depending on its source or label, such as gambling freely with house money from recent profits. It leads traders to take reckless risk with gains they would never take with their original capital. also: house money effect

Mental capital Core

The finite reserve of focus, willpower and emotional steadiness a trader brings to the market each day. Like financial capital it can be depleted by stress and losses, and protecting it is part of sustaining good decisions over time. also: psychological capital

Monthly review Routine

A periodic, higher-level assessment of performance, process adherence and goals over a month to gauge progress and adjust the approach. Its longer window smooths out noise and highlights persistent strengths and weaknesses.

Narrative fallacy Bias

The tendency to construct a tidy story that explains market moves after the fact, giving a false sense of understanding and predictability. Compelling narratives make random noise feel meaningful and can justify holding a losing trade.

Opportunity cost Decision science

The value of the best alternative given up when capital, attention or risk budget is committed to one trade rather than another. Recognising it discourages tying up capital in stagnant positions that block better opportunities.

Optimism bias Bias

The tendency to overestimate the likelihood of good outcomes and underestimate the bad, so traders assume the market will move their way. It underlies neglected stops, undersized risk buffers and the belief that a losing trade will surely recover.

Overconfidence Core

An inflated belief in one's knowledge, skill or the precision of one's forecasts that leads to oversized positions and neglected risk. It typically grows after a run of wins, exactly when caution is most needed. also: overconfidence bias

Overconfidence bias Bias

A systematic overestimation of one's own knowledge, accuracy or control, leading to excessive trading, oversized bets and under-hedged risk. Research on retail traders links overconfidence to higher turnover and lower net returns.

Overreaction Behavioral finance

The tendency of markets to move too far in response to news as emotion amplifies the reaction, later partly reversing. Overreaction underlies mean-reversion setups and reflects the crowd's difficulty in weighing new information calmly. also: market overreaction

Panic Emotion

An acute fear response that causes sudden, unplanned action such as dumping a position at the low of a selloff. Panic overrides the plan entirely and is a major reason traders realise losses at the worst possible moment. also: panic selling

Panic selling Behavioral finance

A rapid, fear-driven wave of selling in which participants exit at almost any price to escape further loss, feeding a sharp decline. It often marks capitulation near a bottom, when the crowd is most fearful and prices most dislocated from value. also: capitulation

Patience Core

The capacity to wait for setups that meet predefined criteria rather than forcing trades out of a need for action. Patience keeps a trader out of low-quality trades between genuine opportunities, which is often where an edge is preserved or destroyed.

Performance review Routine

A structured periodic assessment of trading results, process adherence and behaviour against goals, used to guide improvement. Unlike a single trade review it looks across many trades to separate skill and edge from luck and noise.

Post-trade review Performance

The structured examination of a completed trade against its plan to judge whether the process was followed, separate from whether it won or lost. Regular post-trade review converts individual trades into lessons and is central to deliberate improvement. also: trade review

Pre-trade routine Performance

A fixed sequence of preparation and checks completed before entering a trade, covering setup validity, risk, sizing and market context. It ensures decisions are made calmly and consistently rather than reactively once a position is on. also: pre-trade checklist

Probability thinking Decision science

Treating each trade as one draw from a distribution of outcomes rather than a prediction that must come true. It shifts focus from being right on a single trade to making decisions with positive expectancy over many trades. also: thinking in probabilities

Process goal Performance

A goal defined in terms of actions within a trader's control, such as honouring every stop or journaling each trade, rather than an outcome like a monthly return. Because process goals are controllable, they build discipline without the pressure of chasing results.

Process versus outcome Decision science

The distinction between the quality of a decision and the result it produced, which can diverge because markets are probabilistic. Judging performance by process protects a trader from abandoning a sound method after unlucky losses or trusting a reckless one after lucky wins. also: process vs outcome

Prospect theory Behavioral finance

Kahneman and Tversky's model of how people choose under risk, showing that they value gains and losses relative to a reference point and feel losses more heavily than gains. It explains loss aversion, the disposition effect and risk-seeking to avoid a sure loss.

Rational decision Core

A choice made by weighing probabilities, expected value and predefined rules rather than by immediate emotion. In trading it means acting on the process even when it feels uncomfortable, such as taking a valid stop-loss without hesitation. also: deliberate decision

Recency bias Bias

The tendency to overweight recent events and assume they will continue, so a few wins breed overconfidence and a few losses breed fear. It causes traders to abandon a sound plan after a normal losing streak or to oversize after a hot run.

Reference point Behavioral finance

The baseline, often the entry price or breakeven, against which prospect theory says people judge outcomes as gains or losses. Because feelings hinge on this anchor rather than absolute wealth, the same price can feel like a win or a loss depending on the reference.

Reflexivity Behavioral finance

George Soros's idea that participants' biased perceptions influence prices, and those prices in turn change the fundamentals, creating self-reinforcing feedback loops. Reflexivity helps explain why trends and bubbles can persist far beyond what fundamentals alone justify.

Regret Emotion

The painful feeling of wishing one had acted differently, whether by taking a missed trade or avoiding a loss. Regret aversion causes traders to hesitate on valid setups and to hold losers to postpone the regret of realising a loss. also: regret aversion

Resulting Decision science

The error, named by Annie Duke, of judging the quality of a decision solely by its outcome rather than by the process used. A winning trade taken by breaking rules is a bad decision that happened to work; resulting hides that lesson. also: outcome bias

Revenge trading Emotion

Entering impulsive trades to win back a recent loss, usually with oversized positions and no plan. It is driven by anger and ego rather than edge and is a leading way traders convert a manageable loss into a serious drawdown. also: revenge trade

Rule-based trading Decision science

Making trading decisions by predefined, testable rules rather than discretion in the moment, so emotion has less room to intervene. Rules convert judgment made calmly in advance into consistent action under pressure. also: mechanical trading, systematic decisions

Scenario analysis Decision science

The practice of mapping out multiple ways a trade or market could unfold and planning a response to each in advance. It reduces surprise and reaction, so a trader executes a prepared plan rather than deciding under stress. also: thinking in scenarios

Screen time discipline Routine

The deliberate management of how long a trader watches the market to avoid the impulsive, low-quality trades that boredom and fatigue produce. Stepping away when no valid setup exists protects both capital and mental capital.

SEBI F&O study Routine

SEBI's research finding that a large majority of individual traders in the equity derivatives segment lose money, with losses concentrated among the most active. It is a sobering base rate that underlines why discipline and risk control, not confidence, drive survival. also: SEBI derivatives study

Self-attribution bias Bias

The tendency to credit successes to one's own skill while blaming failures on bad luck or outside forces. It blocks learning and feeds overconfidence, because losses are never examined for the mistakes that caused them. also: self-serving bias

Self-awareness Core

The ability to notice one's own emotional state, biases and impulses in real time and to see how they are affecting a trading decision. It is the foundation of behavioural change, because a pattern cannot be corrected until it is first observed. also: emotional awareness

Status quo bias Bias

The preference for keeping things as they are, which makes traders hold existing positions or cling to a failing strategy simply because change feels risky. It can keep capital tied to trades that no longer meet their original criteria.

Stress Emotion

The physiological and mental strain of trading under uncertainty and financial pressure, which narrows attention and pushes decisions toward short-term reactions. Chronic stress degrades judgment and is managed through sizing, routine and breaks. This is educational information, not psychological or medical advice; if distress affects your daily life, consult a qualified professional.

Sunk cost fallacy Bias

The tendency to continue an endeavour because of resources already committed rather than its future prospects. A trader holds a losing position to justify the time and money already invested, letting a small loss grow into a large one. also: sunk-cost fallacy

Survivorship bias Bias

The error of studying only the successes that remain visible while ignoring the failures that dropped out of view. Focusing on the handful of traders who got rich, and not the many who blew up, gives a dangerously optimistic picture of the odds. also: survivor bias

System 1 Decision science

Kahneman's term for the brain's fast, automatic, intuitive mode of thinking that runs effortlessly and is prone to bias. In trading it produces snap reactions to price moves, which are efficient but often exploited by fear and greed. also: fast thinking

System 2 Decision science

Kahneman's term for the brain's slow, effortful, deliberate mode of reasoning that handles analysis and self-control. Sound trading uses System 2 to build rules and plans in advance so that System 1 does not make decisions in the heat of the moment. also: slow thinking

Tilt Emotion

An emotional state, borrowed from poker, in which frustration or overconfidence pushes a trader to abandon their rules and take reckless trades. Recognising tilt and stepping away, often enforced by a daily loss limit, prevents an ordinary loss from spiralling. also: emotional tilt

Trade preparation Routine

The pre-market work of reviewing levels, news, risk limits and a watchlist so that decisions during the session follow a prepared plan. Good preparation shifts effortful thinking to a calm time and leaves execution to clear rules. also: market preparation

Trading journal Performance

A record of every trade with its rationale, setup, size, risk, outcome and emotional state, kept for review. It turns experience into feedback, exposes recurring mistakes such as oversizing or breaking stops, and is the main tool for improving discipline. also: trade log, trading diary

Trading plan Performance

A written set of rules covering setups, entries, exits, position sizing and risk limits, decided before the market opens. Following a plan replaces in-the-moment emotion with predefined decisions and is the backbone of consistent execution. also: trading rules

Trading psychology Core

The study of how emotions, cognitive biases and mental habits shape a trader's decisions, and how to manage them so that a plan is followed under pressure. It treats the mind, not the strategy, as the variable that most often decides whether an edge is actually captured. also: market psychology, trader psychology

Trigger Routine

A cue, situation or emotion that reliably precedes a particular behaviour, such as a losing streak triggering revenge trades. Identifying personal triggers lets a trader design routines that interrupt harmful patterns before they start. also: cue, emotional trigger

Weekly expiry stress Routine

The heightened emotional pressure around NSE's weekly index option expiries, when rapid time decay and sharp late-day moves intensify fear, greed and the urge to overtrade. Recognising it as a predictable trigger helps traders pre-set rules for expiry days. also: expiry-day stress

Weekly review Routine

A regular end-of-week examination of trades, adherence to the plan and emotional patterns to extract lessons and set focus for the next week. It operates at a higher level than a single post-trade review, revealing trends a daily view can miss.
