EUR / USD 1 minute strategy

This strategy is a combination of 3 indicators, SuperTrend, Parabolic SAR and MACD; also including the Range. A trade entry is generated following the switch of the Parabolic SAR from BUY to SELL or vice versa, after a longer Parabolic SAR run (the aim of this is to ignore shorter term price changes and focus on more significant trend changes). The attachments and performance is based on only £1 per pip, producing an approximate 9% return every 3 months. Compounding the trade size as your capital grows should produce a reasonable return (i.e. use the 2% compounding model as per Bob Volman’s book (2011) on FX scalping.

However this is far from perfect as I would like to improve the Win / Loss ratio. So any comments and improvements are welcome!
