Overconfidence after a win streak

After a string of winning trades, your brain rewires itself to think you're a genius. You feel invincible. You increase position size. You skip the analysis. Then the market reminds you it doesn't care about your win streak.

The pattern

Trade 1: small win. Trade 2: bigger win. Trade 3: huge win. Trade 4: 'I should size up. Clearly I'm in flow'.

Trade 5: catastrophic loss that wipes out half the prior gains.

> Win streaks feel like skill. They're usually a combination of luck and a favourable market environment that will change without warning.

Why it happens. Confirmation bias + hot hand fallacy

The brain looks for patterns. Three wins in a row feels meaningful. You start believing you've 'cracked the code'. In reality, three wins in any random sequence is common.

Professional poker players, sports gamblers, and traders all show the same pattern: their worst losses come right after their best wins.

Indian retail context

2020-2021 bull market: many first-time traders thought they were stock-picking geniuses. Everything went up. By 2022-2023, when the market corrected, the same traders lost most of their gains.

The market was the genius, not the trader.

How to manage overconfidence

1. Cap position size, never increase beyond your 2% rule, regardless of win streak

2. Track win rate over LONG samples (50+ trades), not the last 5

3. Force yourself to take losses when stops hit. Don't let one good streak become an excuse to abandon discipline

4. After 5 wins in a row, REDUCE size for the next trade, counterintuitive but disciplined

Winsstay humble

Lossesstay calm

Bothstick to the rules

Takeaway. Win streaks rewire your brain to feel invincible. The worst losses follow the best win streaks. Cap position sizes, track win rate over 50+ trades, and consider reducing size after consecutive wins, counterintuitive but disciplined.
