My strategy (EMA73)works on eurusd ,and one hour period, the indicators used in this strategy are (ema) period (3) and ema period (7) (MEDIAN_PRICE). The script of the strategy use onBar class; with the opening of each new bar ; relative position of ema (3) and ema (7) decides what position will be opened. Shorts : if the difference (diff1 = ema (3)-ema (7)) is positive then it is a short position at market price . Stop Loss is 63 pips above Open of the last bar closed (the stop is variable) . Take Profil is 18 pips below the Close of the last bar closed . long : if the difference (diff2 = ema (7)-ema (3)) is positive then it is a long position at market price . Stop Loss is 63 pips below Open of the last bar closed (the stop is variable) . Take Profil is 18 pips above the Close of the last bar closed . The ratio (TP /Stop ) and the percentage of winning positions are key to the success of this strategy . Need over time to ensure.
