Hello!
One of the ways I am using, I share it in the course Forex Expert Advisor course – London, New York & Tokyo Algorithmic trading.
I show in the course how to generate strategies just for the London session or the New York and Tokyo. This way I can generate strategies that will open and close withing those 8 hours(average) trading session. This way no trades last overnight, swap out of the equation and the strategies are quite scalping.
