ema
You can decide to trade with this very simple scenario. This system consists of 2 exponential moving averages ( EMA ) These are Ema 8 and Ema 20.
Recommended period is 4 hours.
When 8 Ema is above 20 Ema , positive zone and may be safer to trade. And the opposite is negative when it is.
This indicator is of course not a sufficient reason to decide on trading. It can only be one of the signals to guide.
