I posted “Bullish and Bearish Forex Screeners (based on 3 indicators)” about 4 months ago and had a lot of suggestions and support from @Nicolas, @Sofitech and @Doctrading to develop an automatic trading system.

Well, after a lot of testing, I have come up with the attached system.  It seems to be happier in the longer time frames viz. H4 up.  I have posted it with two variables, a and b, which are the parameters for the SuperTrend indicator.  Since this is the exit signal, it is important to optimise these variables for the instrument you plan to trade.  Then enter the results of the optimisation into the code and prepare it for automatic trading.  I suggest you test it forward first before committing real money.

I found a wonderful site for the procedures involved in creating and testing a strategy at https://trading.prorealtime.com/en/create-a-trading-system, for those of you who haven’t found it already.

I have also attached the results from 4 tests, of which the DAX was the most spectacular, with 2000% gain in about 15 weeks.  However it had the largest drawdown.

So have fun playing with this.  I look forward to your suggestions for improvements.
