Quote from Godpods:
Price action is the only sustainable edge and there is only one way to learn it.. as soon as someone starts talking about backtesting or paper trading I know they are unprofitable
and as soon as someone starts talking about backtesting being a waste of time and only interested in forward testing, I know they're unprofitable.
actually, the only people I've heard downplay the value of backtesting are you and TRO.
