Reviewing one-minute charts after the fact lies to you

[Amanhasnoname]

Scroll back through yesterday's one-minute chart and every trade looks obvious. The level held, the rejection candle is textbook, the loser had a clear warning sign three bars earlier. That clarity is hindsight bias, and it is strongest on short timeframes because the entire sequence fits on one screen with the outcome already visible.

The danger is in what it teaches. After enough of these reviews, the conclusion becomes "should have seen that", and the rules get tightened or loosened around a picture that nobody had in real time. A plan built on that can fail the next day because the supposedly obvious signal was only obvious with the right half of the chart revealed.

A fix that costs a few minutes: review with the chart replayed bar by bar, or with the right side covered, and write down at the moment of entry what was known and what the rules said. Only then reveal what happened. Judge the decision on whether it followed the plan, not on the outcome.

Also separate two review questions. Was the trade valid under the rules? And, separately, is the rule worth changing? Mixing them is how plans get rewritten from single examples.

Who uses bar replay for reviews, and does it change the conclusions compared with just scrolling?
