What is Hindsight Bias?

Indian market context (NSE)

Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how Hindsight Bias shows up on Indian index, equity, and futures books — update to live quotes in your journal.

Nifty 50 perspective

Hindsight Bias often appears after Nifty moves 150+ points from open while you waited — journal “Nifty FOMO” entries separately from A-grade setups at 24,300 levels.

Reliance Industries perspective

Hindsight Bias on Reliance trades is common around results noise at ₹1,300 — rate discipline 1–5 in TradeLyser even when P&L is green.

Bank Nifty futures perspective

Hindsight Bias after Bank Nifty whipsaws 200 points around 55,000 triggers revenge sizing — enforce max daily loss before re-entering MIS.

How to validate

• Validate Hindsight Bias tags against time-stamps — impulse entries cluster after losses.
• Compare P&L on tagged vs untagged sessions over 20+ trading days.
• Use mentor review to confirm tag definitions stayed consistent.
• Do not validate solely on one exceptional week of discipline.

How to track in TradeLyser

• Add psychology grade and Hindsight Bias-related tag on each trade card.
• Use daily journal mood line when Hindsight Bias risk is elevated.

Common pitfalls

• Labelling trades after the fact to match desired self-image.
• Increasing size to fix a Hindsight Bias episode immediately.
• Confusing a green day with cured Hindsight Bias behaviour.
