Buy cheaper – sell more.

Interesting, what is the simplest trading system, plotted on the oscillator and the reversal candlestick pattern showed quite satisfactory results. No filters, trend-friends, etc..

But, looking at friendliness, many tend to choose a few simple, not very grateful systems, than one super duper.
