Trading Psychology

Knowing a rule and following it under pressure are different tasks. A bias is a regular tendency in how we read information or make decisions. It is something to look into, not proof that someone is a bad trader.

Split one moment into three layers. Observation: ITC closed at ₹363.85 on 1 Jan 2026, down 9.71% (NSE). Interpretation: “It must bounce back because I own it.” That is a thought, not a fact. Action: “Buy more.” That adds money to the same risk.

A trading plan writes down the reason for a position, the evidence that would change it, how much is at stake, how the orders work and when to review. It makes gaps easier to see. It cannot turn an untested method into a profitable one.

When Mr. Chartist feels an urge to act, he asks whether any relevant evidence has changed. Then he checks the cash committed and what could go wrong. He can act, pause or drop the idea. He does not need to feel no emotion before making a careful decision.

Learn the vocabulary, order types and the risk lesson first. If a rule is unclear, learn what it means. If facts change or a rule no longer fits, review it on purpose. Do not obey it blindly, and do not rewrite it just to justify a position you already hold.

Fear is a reaction to a threat. Greed is a strong wish for more gain. Fear can push a rushed exit; excitement can push a bigger position. Neither feeling tells you the next price.

You can see a crowd's feelings in trading volume. On 31 Dec 2025, 99,45,109 ITC shares traded on NSE. On 1 Jan 2026, the excise-duty day, 28,26,26,710 traded: about 28.4 times as many (our arithmetic). On 19 Oct 2026, an ordinary day, 1,15,28,925 traded while the price slipped 1.02%. The huge volume showed strong feeling. It did not say where the price would go next.

Fear can also point to a real problem: the position may be too big, essential money may be involved, or the product may not be understood. Check those facts. Calling every worry “weakness” can hide a real risk-management failure.

Gains create the opposite pressure: “I should put everything in before it runs away.” Before adding more, check concentration (how much depends on one holding or one shared risk), your cash needs and the evidence. Money already earned can still be lost.

Use plain words such as “I feel rushed” or “I want someone to agree with me.” Naming the feeling creates a checkpoint. It is not a forecast, a diagnosis or a promise that the next decision will be right.

Loss aversion is the tendency for losses to weigh more heavily than gains of the same size. Kahneman and Tversky described it in prospect theory (Econometrica, 1979). Research does not give everyone the same “twice as painful” number. How strong it is depends on the person and the situation.

Take a real path with an illustrative holding. Suppose 100 ITC shares were bought at the 31 Dec 2025 close of ₹403.00: cost ₹40,300. At the 1 Jan 2026 close of ₹363.85, they were worth ₹36,385, an unrealised loss of ₹3,915. At the 2 Jan close of ₹350.05, they were worth ₹35,005, down ₹5,295, or 13.14% in two sessions (our arithmetic, before costs).

Unrealised means the shares have not been sold. The fall in value is still real. Selling turns it into a realised result and ends the exposure. Holding keeps both the chance of recovery and the chance of a further fall. Neither is certain.

“It's not a loss until I sell” mixes up accounting with exposure. Tax treatment can depend on whether a loss is realised, and on the country. That does not undo today's fall in value.

Now suppose the plan was to exit at ₹390. That is ₹13 a share, or ₹1,300 of planned risk on 100 shares. Call it 1R, one planned risk unit. On 1 Jan, ITC opened at ₹402.70 and fell to a low of ₹362.70, so the price went straight through ₹390. NSE does not publish where each stop order filled. If the shares were still held, the 1 Jan loss was 3.01R and the 2 Jan loss 4.07R (our arithmetic). R is a record-keeping unit, not a guaranteed limit.

A fill means an executed trade. A stop-market order can fill well beyond its trigger price; a stop-limit order may not fill at all. Liquidity means being able to trade your quantity at an acceptable cost. Check the rules for your market and broker. A written plan cannot create liquidity or insure a loss.

The disposition effect is a tendency to sell winners more readily than losers. Odean documented it in US brokerage accounts (Journal of Finance, 1998). It can look like taking a small gain for relief while keeping a losing position because closing it feels bad. It does not happen in every account.

SEBI's study of individual futures and options traders (published 20 Aug 2026) shows the same shape in Indian data. In FY26, the average loss among loss-makers was ₹1.47 lakh, while the average profit among profit-makers was ₹1.22 lakh, so the typical loss was about 21% larger (SEBI). These averages come from two different groups of people, so no win rate can be worked out from them.

A winner should not be held longer automatically, and a loser should not be sold just because it is red. Review the original reason, what has changed, the risk and the exit method. The problem is replacing those checks with a wish to feel better.

Teaching arithmetic (not real results): if the average win is ₹2,000 and the average loss ₹1,000, you need to win ₹1,000 ÷ ₹3,000 = 33.33% of the time to break even before costs. If wins shrink to ₹700 and losses grow to ₹1,800, you need ₹1,800 ÷ ₹2,500 = 72.00%.

Costs raise the break-even rate further. The sum shows how exit habits change the numbers. It does not prove that any method can reach its assumed results.

A bigger average loss than average win does not, by itself, prove a bias or a broken method. Win rate, costs, extreme outcomes and the method all matter. Look at single exit decisions and what was known when they were made.

Confirmation bias is the tendency to look for, and believe, information that agrees with what you already think. Wason described an early test of it in 1960. After buying, people often read the cheerful opinions closely and skip the unwelcome filings. Agreement starts to feel like evidence.

Picture an ITC holder around 31 Dec 2025. That evening there is an official fact: the Government notified extra excise duty on cigarettes, from ₹2,050 to ₹8,500 per 1,000 sticks by length, starting 1 Feb 2026. There is a dated news report on 1 Jan 2026, after the fall (WION). And there may be the kinds of message everyone gets: a chat forward saying “it's already priced in”, or a screenshot of someone's price target. Those last two are example types, not real posts.

If you hold the shares, the forward feels comfortable and the notification feels like noise. If you do not, it can flip. The reliability of each item does not change with your position: the official notice is still official, and the forward is still unverified.

The same fact also hit companies differently. On 1 Jan 2026, ITC closed down 9.71%, Godfrey Phillips down 17.08%, and VST Industries down 0.80% after touching a low of ₹237.90 (NSE, our arithmetic). Checking the evidence means reading what it means for this business, not just whether it agrees with you.

When you form a view, write what would make you rethink it. Invalidation means the original reason no longer holds. It can be a business fact or a condition in a written method. It is not always the same as a stop order.

Opposing opinions are not automatically right either. Give more weight to relevant, checkable, dated evidence. Do not give an unverified forward the same weight as an official notice.

Recency bias means giving recent events too much weight. A few good months can feel like proof the market only rises. A few bad months can feel like proof it only falls. A short stretch is limited evidence.

The Nifty 50 shows how the view changes with where you stand. It closed at 25,046.15 on 8 Oct 2025 and reached its highest close of the following year, 26,328.55, on 2 Jan 2026: up 5.12% (our arithmetic). Standing there, “it only goes up” felt natural.

By 8 Oct 2026 it had closed at 22,231.80, down 15.56% from that January high and 11.24% lower than a year earlier (our arithmetic, NSE closes). Standing there, “it only goes down” felt natural. By 19 Oct 2026 it closed at 22,888.95, up 2.96% from 8 Oct. Three different moods, one index, one year.

Size often follows mood. Raising your planned risk after a run of wins, or after a rising market, means the next loss lands on a bigger position. This shows how exposure grows; it is not a rule about how streaks end. Wins can continue and losses can cluster.

The gambler's fallacy is believing a win is “due” because losses came first. The opposite mistake is believing a winning streak must continue. Neither follows from the streak alone. A losing streak can be a good reason to review the method, data, execution or how much you can afford to lose.

Use written reviews before changing your rules or size. No fixed number of trades proves an edge. Raising size on a calendar date, or because the account grew, does not make the decision sound by itself.

Revenge trading means taking risk mainly to win back a recent loss, not because a fresh decision meets your plan. Warning signs include rushing, repeated orders, bigger quantities and skipped checks. These are prompts to look at behaviour, not a medical diagnosis.

A constructed illustration: a ₹1,000 loss, then a rushed attempt that loses ₹2,000 with doubled size, then another that loses ₹4,000 with the checks skipped. The total is ₹7,000 before costs. Each step raised the exposure. This is an illustration, not something that must happen.

Real data points the same way. In SEBI's study of intraday trading in the cash market (FY23, published 24 Jul 2024), 71% of individual intraday traders made a net loss. Among the most frequent traders, those with more than 500 trades a year, the share was 80%.

The market does not owe you a recovery. A new trade needs its own evidence and must fit your current cash and risk limits. It may share the same risks as the last one, so a fresh order does not make it independent.

A pause rule written in advance can interrupt the urge to win it back. Do not add new risk while you check open positions, pending orders and obligations. Walking away without knowing your exposure is not the same as managing it.

A pause cannot undo losses or guarantee better decisions. Resume only after a deliberate review; not trading is a valid choice. Repeated urges that override your control may need support beyond the trading screen.

Fear of missing out, or FOMO, is the discomfort of watching something happen without you. A rising price, a profit screenshot or an urgent message can turn watching into pressure to act. The pressure is not evidence that the move will continue.

Use a real session. On 21 Oct 2026, ITC opened at ₹261.00 on NSE and reached a high of ₹264.85. For the arithmetic only, take ₹253.15, its past-year low on 8 Oct 2026, as the exit level. That is a reference level for the sum, not a suggested stop. Assume a ₹1,000 risk budget (a teaching assumption).

Buying at the open, ₹261.00, the distance to ₹253.15 is ₹7.85 a share. ₹1,000 allows 127 whole shares, risking ₹996.95 before costs (our arithmetic).

Chasing to the high, ₹264.85, the distance becomes ₹11.70. The same budget allows only 85 shares, risking ₹994.50. Keeping 127 shares instead puts ₹1,485.90 at risk, about half as much again, before costs and fill differences (our arithmetic).

Moving the exit up just to keep the old quantity changes the plan again. It needs its own reason, not arithmetic designed to make the order look acceptable. Even the smaller quantity may be wrong if the original reason no longer holds.

Young traders feel this pull often. Traders under 30 were 48% of individual intraday traders in FY23 (SEBI, 24 Jul 2024) and 43% of individual F&O traders in FY26 (SEBI, 20 Aug 2026). Recheck reason, price, quantity, cash and exit together. A move you skipped is not a debt you owe yourself.

Overconfidence means feeling more certain than the evidence supports. It can show up as too much certainty in a forecast, too much faith in your own skill, or too little respect for uncertainty. Confidence is not the same as believing a loss is impossible.

Barber and Odean studied 66,465 US households from 1991 to 1996 (Journal of Finance, April 2000). The most active traders earned 11.4% a year, against 17.9% for the market and 16.4% for the average household. That is a gap of 6.5 percentage points a year (our arithmetic). The authors suggest overconfidence can explain the heavy trading.

Experience alone did not fix it in India either. In SEBI's intraday study, 54% of traders with three years of experience (those who traded intraday in FY19, FY22 and FY23) were still making net losses in FY23.

A trader may credit every gain to skill and blame every loss on bad luck. That blocks learning, because chance, conditions and execution also affect results. “I can't be wrong this time” can lead to concentration, borrowing or dropping an exit. A strong opinion does not add cash or reduce the possible loss.

Write your assumptions and uncertainties next to the view. Compare what you expected with what happened, over a fair record that includes costs and losing trades. A flattering sample or paper result cannot prove a reliable edge.

Review the evidence first, the exposure second, then the quantity. Cutting risk, saying no to a product or admitting you do not know enough can all be rational. None of them proves weakness.

Anchoring means letting a first number have too much pull on a later judgement. Tversky and Kahneman described it in Science in 1974. A purchase price, an old high or an account balance you once saw can become a level you believe must come back. It matters for your records. It does not decide future demand.

ITC's intraday high on NSE was ₹426.40 on 31 Oct 2025. Its low was ₹253.15 on 8 Oct 2026, a fall of 40.63% (our arithmetic). On 19 Oct 2026 it closed at ₹260.80, still 38.84% below that high. To get back to ₹426.40 from ₹260.80 it would need to rise 63.50% (our arithmetic). “It was ₹426 once, so it will go back” does not explain why holding makes sense today.

An issue price can be an anchor too. Paytm (One97 Communications) listed on NSE on 18 Nov 2021 with an issue price of ₹2,150. It closed its first day at ₹1,560.80, down 27.40%, and needed a 37.75% rise just to get back to the issue price (our arithmetic, NSE listing-day data).

A sunk cost is a past cost the present decision cannot recover. Hours of research can make you want to keep an idea alive. Those hours do not make the next rupee of risk worthwhile.

The endowment effect means valuing something more because you own it (Kahneman, Knetsch and Thaler, 1990). Owning a share can make bad news harder to accept. Compare today's evidence with your original reason. Holding is not automatically wrong, and selling is not automatically right.

Buying more because a lower average price looks comforting increases the commitment and needs a fresh assessment. A better-looking average does not undo the earlier loss or guarantee a recovery.

Herding means following other people instead of making your own assessment. Social proof means treating popularity as reassurance. Both can affect a beginner surrounded by confident posts or friends talking about gains.

A loud group is not always a well-informed group. In SEBI's Investor Survey 2025 (press release 63/2025, 30 Sep 2025, covering more than 90,000 households), 63% of households knew of at least one securities product, but only 9.5% invested. Among investors, only 36% had high or moderate knowledge of the securities market. Nearly 80% of households preferred keeping their money safe over chasing higher returns.

A profit screenshot can leave out losses, the capital used, borrowing, fees and the time period. It may also be edited. An incomplete, unchecked picture cannot show what happened or what you are likely to achieve.

A message saying “everyone is buying” does not check a company's finances or give you a price you can trade at. Check official disclosures, sources and who gains from the message. The same claim repeated by many accounts is not independent evidence.

Mr. Chartist notes the source, date, supporting facts and uncertainties before reacting. He sizes against his own circumstances, never someone else's quantity. Checking can end in doing nothing.

Discussion can help, but do not turn a position into a public identity you must defend. Changing your view when the facts change is part of research. Rules for advisers and intermediaries differ by country.

Action bias means preferring to do something even when waiting may be better. Boredom, alerts and wanting to feel productive can lead to orders outside your plan. More trades do not make a better method.

A round trip opens and closes a position. Gross means before costs; net means after them. Teaching inputs (not a broker tariff or tax sum): three round trips each make a ₹100 price gain and cost an assumed ₹150. Each nets −₹50. Together, ₹300 gross minus ₹450 costs gives a ₹150 net loss.

SEBI's intraday study shows costs at real scale. In FY23, trading costs made loss-makers' losses 57% larger, and profit-makers paid 19% of their profits as costs. The number of individual intraday traders grew from about 15 lakh in FY19 to about 69 lakh in FY23, about 4.6 times (SEBI, 24 Jul 2024).

Frequent trading raises costs and the number of decisions, but frequency alone does not prove a method is unsound. Judge what each action adds, after costs. Holding for a long time can also lose money.

Decide in advance what deserves your attention and what can be ignored. Monitor in a way that suits the position, rather than searching for a reason to act. “No decision met my plan today” is a useful journal entry.

Outcome bias means judging a decision mainly by how it turned out (Baron and Hershey, 1988). Hindsight bias means believing, after the fact, that the outcome was easy to predict (Fischhoff, 1975). A lucky gain then looks like skill, and an uncertain loss looks like an obvious mistake.

Look at what was knowable, and when. ITC closed at ₹403.00 on 31 Dec 2025. The excise duty was notified late that evening, after the market had closed. On 1 Jan 2026 ITC opened at ₹402.70 and closed at ₹363.85. Someone who bought at the 31 Dec close could not have known the notice was coming. Afterwards, the fall can feel obvious. It was not knowable at the close.

A position that broke a risk rule may still make money; the gain does not make the breach right. A carefully planned position may lose; the loss alone does not prove that available information was ignored.

Following a plan also does not prove the plan was good. Review the method's evidence, how you carried it out, and the result separately. A method followed faithfully that does not work still needs rethinking.

Mr. Chartist writes his reasons and doubts before the result is known, and compares the decision with that record afterwards. That makes it harder to swap in a flattering story later. Include profitable mistakes and losing decisions that followed the plan. One result cannot settle every question.

Tiredness, stress and distraction can affect attention and decisions. One brain-imaging study found that a night without sleep shifted how people weighed gains and losses (Venkatraman and colleagues, Journal of Neuroscience, 2011). Effects differ by person. This lesson does not diagnose any condition or give medical advice.

Poor focus can show up as a wrong quantity, a missed order message or a forgotten position. Use order previews and check your records even when you feel sure. Reconciliation means comparing records to see that they agree. A checklist cannot prevent every mistake.

Money pressure can make a quick recovery feel urgent. Money needed for rent, loan payments or other essentials should not be a trading experiment. A market screen is not a dependable answer to an urgent cash need.

Analysis paralysis is searching again and again because uncertainty feels unbearable. Research helps when it answers a real question; switching indicators for comfort may not. Name the question, the missing evidence, and whether doing nothing is the right call.

Before adding exposure, check four things: attention, understanding of the product, time to watch it, and that essentials are paid with no borrowed money involved. Poor readiness can justify a pause. Open positions and pending orders still need handling.

A useful plan says why an idea is being considered and what would change that reason. Include the sources and their dates. “It looks good” is hard to review; a specific claim with its uncertainty is far more useful.

Write down the session you actually saw. For example: ITC on NSE, 21 Oct 2026, open ₹261.00, high ₹264.85, low ₹260.15, close ₹262.00. Then add the quantity, the money committed, the cash you have, the exit method and a stressed outcome: what happens with worse prices or fills.

Use a real stress case. On 1 Jan 2026 ITC opened at ₹402.70 and touched ₹362.70 the same day, a fall of 9.93% from the open (our arithmetic). Ask what that kind of day would do to this position, next to your other holdings and the money you need elsewhere. Planned loss, the most a product can lose, and what actually fills are different questions.

Know the order type, its validity, its trigger and your broker's limits before relying on it. A rule checked at the close is different from a stop order working during the day. Write down what the order actually does.

A pre-mortem imagines the decision went badly and asks why: a gap, no buyer at your price, an unsuitable product or wrong information. It finds gaps; it does not predict the next outcome.

Set review and pause conditions, including what to do with open positions. If new facts justify a change, write the reason and recalculate the exposure. The aim is accountable change, not obeying an out-of-date document.

A pause rule says when to stop adding new exposure and review. Possible triggers include breaking your plan more than once, poor focus or an urge to win back a loss. A personal loss limit can be one of them, but no single number suits everyone.

First, list open positions, pending orders, obligations and alerts. An order waiting to fill can still create exposure. Cancelling or changing it means confirming its actual status.

A pause is not a punishment. Its purpose is to slow down rushed decisions and make room for review. A break may help, but it cannot replace an exposure check or fix a commitment that was never suitable.

Before resuming, check that the reason for the pause has been dealt with. Do not come back just because another stock is moving. No trade is needed to prove confidence or to restore a number you wanted to see in the account.

If you keep bypassing your own limits, look at the controls your broker offers and consider outside support, rather than promising more willpower. Broker controls differ, so check them. Staying out is a fair choice while the problem remains.

A trading journal records decisions and what followed. Before acting, note the reason, evidence, quantity, planned risk, doubts and how you feel. A note made at the time beats a story put together afterwards.

An illustrative entry on real prices. Before, written on 31 Dec 2025: ITC, 100 shares at ₹403.00, planned exit ₹390, 1R = ₹1,300, feeling calm. After, on 2 Jan 2026: close ₹350.05; if still held, the result is −₹5,295, or 4.07R (our arithmetic). Note: “The fall went straight past the exit.”

Afterwards, record fills, costs, any changes and why they happened. Tell apart a signal you missed from an order you sent that did not fill. Screenshots can support the record, but keep the prices, quantities, dates and order status too.

Look for repeated behaviour: bigger size after wins, looking for agreement after losses, trading when bored. Patterns are clues, not diagnoses. Check whether the method, the data or your setup also played a part.

When you use R, keep the first planned risk as the measuring unit, so a wider exit later cannot rewrite history. Keep the rupee amounts and account exposure as well. R makes trades comparable; it does not replace what happened to your money.

Choose one specific change and check whether it fixes the problem. A missed quantity check might call for an order-preview step. A journal supports review; it cannot guarantee profit or prove cause from a few chosen examples.

Know the base rate before you start. SEBI's study of individual traders in equity futures and options (published 20 Aug 2026) found that the share who made a net loss was 90.2% in FY22, 91.5% in FY23, 91.1% in FY24, 90.9% in FY25 and 87.7% in FY26. Before transaction costs, the FY26 figure would have been 82.1%. Individuals' combined net loss in FY26 was ₹91,685 crore.

Many people stepped away. Active individual F&O traders fell from 106.2 lakh in FY25 to 87.5 lakh in FY26, and about 46 lakh of the FY25 traders did not trade at all in FY26 (SEBI). Not trading is a real option.

Start by understanding the instrument, the quote, order types, costs and how much you could lose. Practise writing down decisions and checking the arithmetic. Learn the process before you take on exposure that is hard to manage.

Paper practice means simulated decisions with no real money. It can build routines, but simulated fills, liquidity, costs and emotions differ from live trading. Paper profits do not prove future live results.

You do not have to become an active trader. Long-term investing, qualified professional advice or avoiding a product can each suit different situations. Each needs its own check of risks, fees, goals and time horizon.

Repeated loss of control, borrowing to win back losses, hiding activity or harm to daily life needs more than a checklist. Consider qualified professional help or someone you trust. That is a reason to get support, not a diagnosis.

Use one repeatable loop: notice the pressure, examine the evidence, check your exposure, decide on purpose and review honestly. It can make decisions clearer while uncertainty remains. Losses are still possible, and careful behaviour cannot guarantee returns.
