Traders may use leverage to scale up the returns and use stop orders to limit their losses. Typically used for controlling risk, stop loss orders may actually increase long-run trading profit. This paper derives a criterion for maximizing long-run trading profit with respect to leverage and stop loss order placement, as both may affect profitability. In a trading application, we study how stopping losses and leverage affects trading profit. We find empirical support that stop loss order placement together with leverage can have a substantial effect on long-run profit.
