Backtest is Useless?!

[Arya Stark]

"Backtest is useless", they say, until their forwardtest - their live trading - serves as their failed backtest.
People simply cannot expect to make it in such a crazily difficult occupation as trading, when they lack basic common sense. Let's get real, most traders who keep believing their dogmas, even though they keep losing for years, don't need trading education, they need to first develop some logical thinking.

There are many software emerging these days helping backtesting and i believe back test is as important as the forward testing before going to trade with live funds, all of the rest is secondary.

In my system development, I only trust a strategy after out-of-sample walk-forward and Monte Carlo, not just a pretty equity curve

Sounds perfect!

Lets not call them useless. They just don’t guarantee success 100% and there’s always room for errors.
