My strategy uses EUR/USD. Default time frame: 30Min. Lot size 15M. TP:4 SL:200 pips. It gets historical candles called base candle and signal candle. According to combinations and some comperations between candle open-close-high and low prices, we have 4 logic to open position. 1. GREEN/GREEN (BUY Limit) 2. RED/GREEN (BUY Limit) 3. RED/RED (SELL Limit) 4. GREEN/RED (Sell Limit) . For live trading it has options for only short or long. But for this contest i had to keep it symmetrical. Good luck and take care traders.
