I speak about the multiple factors that will hinder your potential REAL lie profit when you go live with any forex or crypto asset class broker/exchange. Back testing will not help you here when you need to factor items like slippage or momentum of an instrument. There may be accusations if the broker/exchange can cheat you out. In essence, no matter what you trade it could be a struggle or even waste of time. This is why I am thinking USA future/options is better asset class since it is heavily regulated. On the strategy bot side, your win loss ratio will be the king to overcome all this stuff.
