How to modify the leverage?

 

Hi there!

I know I know I know, you've probably heard this one about 1000nd times before, but still, please help me out, it's really driving me nuts

I tried opening a new account with leverage 20, but upon checking the account leverage using the function

FileWrite(handle,"Leverage:",AccountLeverage());

it always tells me my leverage is set at 500!

is there any way possible to modify the leverage, perhaps also individually for the tester settings?

btw. I also tried including the FXTHeader.mqh, without any luck though.

Thanks!
