Stop loss vs Stop out


Look-alike pair

Full entries: Stop loss · Stop out.

Stop loss is an order you place to exit a position at a chosen price, while stop out is the broker's forced closure of your position when your account no longer meets margin requirements. The single difference that matters is who initiates the exit and why: you set a stop loss for risk control, but a stop out is triggered by the broker's margin rules.
