If you plan on using higher than low risk settings with the Perceptrader AI EA, I recommend having a higher than 1:30 leverage. With a 1:30 leverage, you can only use low risks. Otherwise, you may run out of margin one day. After all, that's the reason for leverage restrictions - to make sure you can't use high risks in trading. However, if you are satisfied with using low risks, you can use them with such leverage.
