Recency bias: why your last 5 trades lie
Three losses in a row and the strategy feels broken. Three wins and you feel invincible, ready to size up. Both feelings come from the same glitch: your brain treats the most recent handful of outcomes as if they predict the next one. In a system driven by an edge plus randomness, they don't.
Recency bias is the brain's tendency to overweight the latest information. It's useful in stable environments — if it rained the last three days, betting on rain is reasonable. Markets aren't stable in that way at the scale of individual trades. Your edge expresses itself over hundreds of trades, while any five in a row are dominated by chance.
The hot hand and the cold hand are the same error
After wins, recency bias becomes overconfidence: you size up, loosen discipline, take marginal trades because you “can't lose right now.” After losses, it becomes capitulation: you shrink size, skip valid signals, or change the rules mid-drawdown. Both reactions read a pattern into a sequence that is mostly random, and both damage the edge.
Rules don't have a memory
The defense is structural. A rule-based system sizes the next trade identically whether the last five won or lost, because it has no emotional memory of the streak. That indifference — which feels cold — is exactly the discipline recency bias destroys in humans. It's a core reason intuition underperforms a tested process you simply execute.
Your last five trades feel like a forecast. They're a coin-flip sequence inside a long edge. Size by the rules, not by the streak.
