Size a position from the risk you’re willing to lose, not from a round lot. Enter your capital and the trade’s levels — the stop distance decides the share count.
Enter your capital plus an entry and stop to size the position.
shares = (capital × risk%) ÷ (entry − stop)
Risking a fixed 1% per signal is the house rule behind every screener’s how-to. It keeps one loss from being career-ending and lets a 60-odd percent win rate actually compound. The stop, not conviction, sets the size.
