This is my first strategy. It is a simple symmetric strategy. I use data (close and open) of historical candles only. When the last candle size (close - open or open - close) > 10pips and the opposite last but one candle size > 1pips and < 80% of last candle size strategy opens an order in the direction of the last candle. For the last candle size 10-15pips TP = 10, SL = 20, for 15-20pips TP = 15, SL = 30, for 20-25pips TP = 20, SL = 40, for 25-30pips TP = 25, SL = 50, for >30pips TP = 30, SL = 60. The trade amount is also different for these candles and changed from 1 to 6 once a month, depending on the expected market volatility. It works with EUR/USD on 15min.
