backtesting doesn't work, period. You have to account for slippage, server outage, and many other factors. Besides, MT4 platform is unstable, and the free data feed you use for backtesting is not reliable.

Just some factors. Also consider a simple cross-over MA system with backtesting, it's real cool with backtests, however try to trade it naked live, and you will see what I mean.

CatFX is profitable, I could see that, I use it for confirmation of short-term trends and retracements.

Interesting idea about pyramiding though, would be interesting to watch how that idea evolves with this system.
