Hello everyone,

I have the pleasure to share with you this simple but practical, universal daily strategy (for Forex, Indices, and Stocks), optimized on the CAC from 1992 to today. I hope that this opensource contribution can bring more developments in the field of automatic trading strategies on prorealtime, and demonstrate once and for all that a strategy to work does not necessarily have to be complicated, indeed (as I see it) the simpler it is, the more likely it is to work in the future as in the past.

• Brief explanation

The strategy has 3 fundamental parameters to optimize primarily which are: Period, Mode, and invertsignal. Once these have been chosen, we move on to the optimization of the two filters: filter1 and filter2. Finally, if you want you can add, a stop loss based on the average true average.

Here is the code
