ljyljl5555, i believe the system works the same for 15mins, 30mins TF according to maurizio77.
one thing i would like to ask is it possible for the cross candle to be in the same direction as the EMA always? eg red cross candle (price goes down) and ema 1 cross ema 5 from above. or blue cross candle ( price goes up) and ema 1 cross ema 5 from below.
