Are you talking about position sizing? Thats a big question, particularly when you want to discuss risk (relative, opportunity, liquidity).
My trading has most definitely improved by deliberate entries, considered timeframe and firm exit criteria. I write it down. My % of winning trades fluctuates with the market still, but position sizing - being somewhat personally subjective can (when I get it right) magnify the profits on the winning trades and minimise the losses on the forced exits (at my exit criteria).
