how do you know a strategy fits YOU and not just looks good in a backtest

[nathanx]

ive got a backtested strategy with solid numbers but trading it live feels wrong, like im wearing someone elses clothes. i hesitate on entries, dislike the holding times, second-guess the exits. the stats say its good but it doesnt feel like mine. how do you tell whether a statistically sound strategy actually fits you as a trader, separate from whether it backtests well?

[Dean]

a good backtest and a good fit are two different things and you need both. the tell that a strategy doesnt fit you is exactly what youre describing, persistent hesitation and second-guessing even when the rules are clear. that friction means youll execute it poorly under pressure no matter how good the stats are, and poor execution destroys a good strategys edge. a worse-backtesting strategy you can execute flawlessly often beats a better one you keep fumbling. fit is part of the edge, not separate from it.

execution is part of the edge, completely agree. the holding time mismatch you mentioned is a classic fit problem, if a strategy holds trades longer than your temperament tolerates, youll exit early and never capture the results the backtest assumed. the backtest had infinite patience, you dont. a strategy only delivers its backtested numbers if you can actually run it as designed, and constant discomfort means you wont.

doesnt feel like mine is also exactly what people say right before they abandon a perfectly good strategy because following rules is boring and they crave the dopamine of discretion. sometimes the discomfort isnt misfit, its just the unglamorous feeling of disciplined trading, which never feels exciting.

[dreamchaser]

the troll names the crucial confound, you have to separate this strategy genuinely fights my temperament from disciplined trading is just boring and i miss the action. the test i use, does the discomfort come from a specific structural feature like holding time or trade frequency that clashes with my life and psychology, or is it generalised boredom that would attach to any rule-based approach. structural clash is real misfit worth changing for. generalised boredom is the discipline you have to build regardless. be honest about which one youre feeling, because the cures are opposite.

structural clash means misfit, generalised boredom means build discipline. tell them apart.
