Hello, you are absolutely right, Jacpin. The best thing would be to test a Demo account with higher leverage, and you can do it 100% same as your live account. This way you will see what will be the different. basically as Petko said, there will be no difference in the performance, but you will see more free margin to trade with.
Higher leverage for us, the algo traders, will be useful if we trade many EAs in small account. I did not see a need to higher the leverage, because I trade small number of EAs on relatively big account(according to me).
