Your fill is a historical accident. It is the least relevant number still on the screen once the trade is open. The market does not owe you a return visit to 1,842.50 because that is where you clicked. Anchoring bias — treating an arbitrary reference as informative — is the name Tversky and Kahneman gave this habit in Judgment under Uncertainty: Heuristics and Biases (1974). On a trading ticket the arbitrary reference is almost always the entry.
You do not talk yourself out of the anchor. You hide the number and see whether your management language survives.
Why the entry is a bad reference
Price after entry has two jobs that matter:
- Distance to the invalidation you wrote before the click.
- Distance to any profit law you wrote before the click.
Neither job cares whether the print is above or below your fill. "Back to even" is not a structure. "Gave back half" is not a structure. "It's underwater versus my average" is bookkeeping, not a chart.
Thinking in R already tries to dethrone rupees. Anchoring can survive R if you still manage from "0R" as a sacred line. 0R is just the entry with a nicer unit. The live questions are: has invalidation printed, and has a profit law printed?
Indian session colour, as hypothesis not folklore: the 09:15–10:00 window prints ugly excursions against almost any fill. If your management rule is "I need to see green first," the open will train you to scratch. Midday may flatter the same rule. That is session artefact, not wisdom.
Entry-Price Blackout: a checklist you can fail
Print this card. Run it on hidden-date replay with the P&L column covered — tape, notebook, or a sticky note on the monitor. Hypothetical size still uses a frozen 1R. You may know the stop distance. You may not know whether the trade is currently a win.
Before entry
- Setup tag spoken
- Invalidation marked on the chart, not "below entry"
- Profit law written (target, trail trigger, or time)
- Entry price will be recorded in the log after the session, not used mid-trade
While the trade is open (each bar)
Ask only:
- Has the invalidation print occurred?
- Has a profit law fired?
- Has a written time-stop fired (including intraday square-off if that is your product)?
If all three are no, the only legal action is hold. If you feel an action coming, name the banned phrase you almost used:
| Banned phrase | What it is actually doing | Tag |
|---|---|---|
| "Let me get back to even" | Treating fill as a magnet | anchor-even |
| "I'll add to improve the average" | Using fill as a permission slip | anchor-add |
| "It's only a small red" | Comparing to fill instead of to stop | anchor-small |
| "I don't want a loss on the day" | Session P&L as a second entry | anchor-day |
| "Nifty is at my buy zone too" | Imported someone else's fill | anchor-index |
One tag per urge, even if you hold. Holding with an anchor-* tag is still useful data. Acting on it is a process 0.
At exit
- Exit law quoted from the morning page
- If the sentence you actually used contains the fill, retag as relief or hope — see relief exits and hope replacing the stop
- Only now uncover P&L and write the fill in the log
Twenty open-trade management decisions (holds count). Count anchor-* tags versus actions. The ratio you want is high tags, zero actions — you noticed the magnet and did not obey it.
Failure modes (the checklist is easy to fake)
- Uncovering "to size the trail." Trails that need the fill are poorly specified. Specify structure or ATR from the chart, as in stop types compared, not "lock 50% of open profit" if that formula requires staring at the fill.
- Even as a secret target. You flattened at the fill and wrote
exit-rulebecause "scratch at even" was added during the trade. Mid-trade law is an anchor with a timestamp. - Average-down as a system. If scaling in is not a pre-written experiment with its own invalidation, it is
anchor-add. Do not discover it on a red Bank Nifty morning. - Delivery confusion. A swing hold can sit red for days and still be valid if invalidation has not printed. Using the daily close versus your fill as the only management input is still anchoring. Use the level.
- Confirmation shopping. You keep the fill visible and add indicators until one of them "explains" why you should wait for even. That is confirmation bias on charts, recruited to defend the anchor.
What blackout does not claim
It does not say entries do not matter. Entries matter at decision time: location versus structure, stop distance versus 1R, liquidity of the name. After the fill, that number has done its job. Management is a second experiment.
It does not say you should ignore unrealised P&L in live trading forever. Live capital has constraints this drill cannot simulate. The drill asks whether your language still works when the fill is hidden. If it does not, live P&L will not rescue the language. It will amplify it.
Do not cite a percentage of traders who "give back to even." You do not have that number. You have your tag counts.
If hiding a practice P&L column leaves you unable to continue — not annoyed, unable — end the session. This is a reference-point drill, not an exposure therapy programme.
Cover the fill. If the sentence still needs it, the sentence is the problem. Join the waitlist.
