My strategy is based on simple moving average with period 200, TF 4 hour, trade at EURUSD with one hour period. If the price is above SMA 200 TF 4 hour and last bar's close price > last bar's open price and last bar's open price = previous bar's open price and last bar's close price >= previous bar's close price then it is a buy signal. If the price is below SMA 200 TF 4 hour and last bar's close price < last bar's open price and last bar's open price >= previous bar's open price last bar's close price
