The indicator calculates the momentum of bullish and bearish based on the average true range and the highest highs and lowest lows of the historical price.
The indicator displays the strength for either taking a long position, or a short position. The simplest way to use the indicator is to take a long position when the M+ line crosses above the 0 line. Similarly, to short, the M- line should cross above the 0 line. The exit would be when the respective line crosses below the 0 line. The contrarian traders should wait for the lines to start rising towards the 0 line and taking an exit. In essence, the line should be going from negative to 0. The greater the divergence between the M+ and M-, the stronger the trend. The small table of Long and Short suggests what is in strength. A 100 will show a strong trend in the respective direction. It will be 50-50 when there is no clear direction, ideally identifying a consolidation range.
