Decision Fatigue — Definition, Examples, How to Fix
Cognitive overload from too many decisions — quality of subsequent trades drops sharply, often to random or impulsive entries.
What it is
After multiple emotional trades, the trader's decision-making capacity is depleted. Setups that should be passed are taken; entries are made without checking the prior steps; risk is no longer being calibrated. The trader is operating on autopilot, taking trades because they are bored or because not trading feels worse than trading. This is the stage where session-ending blowups happen.
What it looks like
- Trades #9, #10, #11 in a session that should have stopped at #5.
- Taking a setup without checking the higher timeframe.
- Hitting "buy" on a chart you haven't fully analysed.
Why it costs you money
Win rate drops 20-30% on trades taken in decision fatigue compared to morning baseline. Average loss size also grows because risk-checking is impaired.
How TradeSaath detects this
TradeSaath counts trades per session and compares win rate by trade-number ordinal. When trades 7+ have meaningfully lower win rate than trades 1-3, decision fatigue is flagged.
How to fix it
- Set a hard cap on trades per day — typically 5-8 for active intraday.
- Stop trading once the cap is hit, regardless of P&L.
- Take a 30-minute break after every 3 trades to reset.
- Track win rate by trade number — the data will show your personal cap.
