SWAVE

This uses combination of
1. EMA difference
2. stochastic

Green column = up move
Red column = down move
Silver column = neutral

リリースノート:

Below changes
1. EMA difference seen in reference to smooth stoch instead of stoch to give better smooth result
2. option to plot both smooth stochastic and ema difference

Results: will give smooth entry exit signals and serve as multi indicator plot
