when using leverage we traders should create a good plan, otherwise using leverage ratio can be useless.
Beginners can prefer trading with lower lots and can use leverage upto 1:100 to check their performance in a real time trading environment.
Knowing how to choose the right leverage is definitely important. Leverage is always a double edge sword and I find newbies tend to overuse their leverage so they end up with a huge loss. Personally i would suggest start with a lower leverage like 1:50 - 1:200 max
leverage most of the tine works to fail when you have poor money management including lo trading plan.
