Projection Bands

Projection Bands were developed by Mel Widner, Ph.D and were introduced in an Technical Analysis of Stocks & Commodities magazine article in July, 1995.

Projection Bands

Indicator Description

You may calculate the Projection Bands by establishing the highest high and lowest low in the n bar lookback period. The bands plot parallel to a regression line of the high/low and indicate potential areas of support and resistance.

As the name indicates, the indicator plots bands, not the channel lines as with the standard Regression Channel, Daily Regression Channel and the Raff Channel.

Should you see prices reach the upper band, it may indicate an overextension and a bearish reversal setup. Opposite, if prices reach the bottom band it may indicate bullish reversal opportunities.

Because the indicator locates the highest high and lowest low in the n bar lookback period, prices will never break above or below the Projection Bands.
