“Stop Level” is the minimum parameter where traders can set pending orders like “Take Profit” and “Stop Loss” from.
In case, the Stop Level is 1 pip, then traders cannot set any types of pending orders closer than 1 pip to the current market price. In this case, the platform may respond with error message.
In fact, FBS doesn’t have “Stop Levels” as the broker has gotten rid of the parameter in September 2017.
On FBS MT4 and MT5, you can set Take Profit and Stop Loss orders anywhere you want without any limitations.
