Stochastic ATR Volatility Oscillator

NOTES: As x, k and d use;
21-10-3 for 1 Hour candles
5-4-2 for 4 Hour candles
21-21-3 for 1 Day candles

Yellow plot is the main oscillator. Orange plot, and hlines at 20, 50 and 80 can be used as signal lines.
I personally use hlines as the signal in 1H as it's the best timeframe for the indicator.

If you are in a long position, sell when yellow plot crosses 80 or 50 line downwards;
and buy when the line crosses 20, 50 or 75 upwards while you are not in a trade.
