I agree with Martin.
That all sounds wise.
Yes, certainly, but I'd want the win-rate to be very well and convincingly proven, and really reliable.
That's the theory.
In practice, unless either you're trading very big positions, or the trading frequency's very, very high, you'd probably want it to work reliably two thirds of the time, to be worth doing, with that R:R ratio.
But if it does, I'd certainly do it.
"Generally"? Most retail forex traders aren't consistently profitable, so I suggest that you certainly shouldn't do what's "generally" done, and that you also shouldn't be averse to doing things that aren't generally done. You need to do better than and different from what "most people" are doing, to make steady profits.
