The stop order is used to protect your capital if the price of the asset falls. Or, in order to guarantee a decent gain in case it rises suddenly. The stop order only allows you to set a purchase at a price higher than the current one or to set a sale at a price lower than the current one. Only when the cryptocurrency reaches the stop price, i.e. the price you have set, is a new market or limit order placed, depending on the specific type of stop order.
