I think we choose high leverage. I think the most important thing is knowledge, strategy & forex experience. So if you have orders of these things then you become a successful full trader in the forex market & max leverage is in your favor. So if you have a little knowledge then you lack or maximum leverage then your loss is high & low profit. Leverage is money I use for trading but high leverage has high risk and high profit. if you use high leverage and use high trading volume then that risk can give you more profit and also can give you much loss. It's bad for new and novice traders to use high leverage high leverage both to run bussens and to take a small profit
