This indicator is a result of experimentation with price action of candle high and lows for quantifying reversals and trend continuation.
The band area shows trend reversal incoming and possible chop. Middle line is the trend reversal price level. Candle colors change if the close price is above or below the middle line. Long and short positions can be taken when above or below the bands. Trend continuations are in effect when price retraces into the bands and breaks above or below in the same direction of the trend.
