Hey C, the 50MA and 50EMA are almost the same, but the 50EMA moves a little faster. But a word of advice I would just use one. Because remember you want to keep your trading as simple as possible. That was the mistake I made when I first started trading I I too many indicators, ma's and etc. Also you need to come up with a rule which should be part of your trading plan. As an idea you for you trade plan you may only consider long entries if the 50 ema is above the 200 ema, but you have to also choose what time-frame (1hr, 2hr, 4hr, D) or you can choose to trade that cross on all time frames.
