What is Anchoring 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 Anchoring Bias shows up on Indian index, equity, and futures books — update to live quotes in your journal.

Nifty 50 perspective

Anchoring 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

Anchoring 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

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

Common anchors on Indian intraday books

Worked example: anchoring to entry on Nifty options

You buy Nifty 24,500 CE at ₹92. Price drops to ₹70. Plan said stop at ₹68. Instead you hold because “it will come back to 92.” It never does; you exit at ₹55. The journal should mark a rule break (stop ignored) and an emotion note “anchored to entry,” not only “market was bad.” Without that tag, your next review will blame volatility instead of process.

How to break the anchor in a trading journal

• Write the invalidation price before entry — that becomes the only stop conversation.
• Hide P&L in R until after the exit decision if your platform allows.
• Ask: “Would I enter this trade now at current price with the same stop?” If no, you are defending an anchor.
• Tag “anchored-hold” whenever you reference entry more than structure in the exit note.

How to validate

• Validate Anchoring 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 Anchoring Bias-related tag on each trade card.
• Use daily journal mood line when Anchoring Bias risk is elevated.
• Dashboard: count psychology violations per week alongside P&L.
• Share tag definitions with mentor before monthly review.

Best practices

• Separate process score from P&L when reviewing Anchoring Bias.
• Use cooldown timers after rule breaches involving Anchoring Bias.
• Sleep on size increases — never add risk the same day as a Anchoring Bias violation.
• Celebrate disciplined losses that followed the plan.

Common pitfalls

• Labelling trades after the fact to match desired self-image.
• Increasing size to fix a Anchoring Bias episode immediately.
• Confusing a green day with cured Anchoring Bias behaviour.
• Skipping tags on “small” impulsive trades.

How to use this in TradeLyser

Add a weekly filter for notes containing entry-price language (“back to cost,” “even”). Correlate those trades with MAE beyond planned stop. Rising counts are a psychology risk flag ahead of size increases.
