EMA Wave Indicator [LazyBear] by LazyBear

This is a 3 EMA visualization tool. Relative momentum across 3 timeframes are rendered as A/B/C waves. Also, helpful in identifying spike/exhaustion bars.

When all the waves are in the same direction, the momentum is very high on that direction. I have made all options configurable, have fun tuning for your instrument :)
