The purpose of this indicator is twice:
- Allowing the user to show a double EMA with the possibility to show when a EMA crossing happens.
- Showing in a more user friendly interface the GDAX ema line.
As a matter of fact is proven that those 2 EMA act as support/resistance during Bulls/Bear periods. The indicator works fine in the GDax timeframes, or rather 5m, 15m, 1h and daily excluding 3h and 6h as they're less used at the moment.
