The fixed stop loss feature can be used when you are trading with a fixed stop loss. For example, when you know how far the stop loss should be, this tool is for you. Check out the video below to see it in action.
A fixed stop loss is often used when a trader is looking to use the same stop size (distance of the stop loss from the entry price). For example, when a trader knows the distance of the stop is going to be 350 points, they would use the Fixed Stop Loss tool to work out their trading requirements. The lot size will then adjust based on the risk percentage and the fixed stop loss position.
