This is standard Williams %R originally written by another user that I modified. Credit to him whose name escapes me at the moment. The green line is 13EMA and red line is 13SMA (offset by 2 for timing trades). Great for very quick trades/day trades. Green over red = long. Red over Green = short.
Beware: this is still a choppy indicator. You'll need to use it with the Ichimoku lagging span, chop indiicator, adx, or some other method of avoiding getting chopped to death trying to take every signal.
