Unless you have exchange membership/extremely low commish scalping is a losing game. Plain and simple. No need to backtest it. Maaaaaany have tried already.Cost $140 for over a decade. I still haven't downloaded it all. Freggin huge. This on the same day I realize my backtesting formula has an error in it and my scalping strategy goes from solid to garbage.
Oh well.
Many will disagree with this but will put up nothing concrete to dispute it.
