The double payment
Every removed bad trade pays twice: its expected loss leaves, and its certain costs, spread, slippage, leave with it, per the cost math. A trader whose bottom-half trades average even mildly negative R is funding that habit at full frequency; halving trade count by dropping exactly those can flip a bleeding month positive with zero new skill acquired.
Why the bottom half exists
Not ignorance, availability: screens open, urges firing, standards negotiable in the moment. The bottom tier is manufactured by presence without process, which is why its cures are structural, trade caps, alert-driven entries, session windows, rather than motivational. The overtrading fixes exist precisely because subtraction does not happen by intending it.
The compounding side
Selectivity's second-order gifts: each remaining trade gets more attention, better execution and cleaner management; variance drops with the noise trades gone, making statistics readable sooner; and the psychological account stops paying the fatigue tax of constant marginal decisions. Fewer, better, bigger-attention trades is not a style preference, it is the direction the arithmetic points for almost everyone below the professional tier.
FAQ
How do I identify my bottom-half trades?
Journal ranking: grade every trade's setup quality at entry, then compare R by grade after fifty-plus trades. The pattern is usually unmistakable.
Will fewer trades slow my learning?
Reviewed trades teach; unreviewed volume just repeats. Fewer trades with full journaling learn faster per hour than churn ever does.
Is there such a thing as too few trades?
At some point sample-building slows, but most retail traders are an order of magnitude away from that boundary in the other direction.
