When the colour changes, it indicates a change in the direction of the driving force, implying a possible reversal.
Accumulation/Distribution (A/D)
A momentum indicator that measures "accumulating" (buying) and "distributing" (selling) to identify the timing of reversals. Such reversals may be signified by instances of divergence: when the price rises but the A/D line falls, or when the price falls but the A/D line rises.

If the lines then converge again, it is considered best to be out of the market.

Directional Movement Index (DMI)
The Directional Movement Index (DMI) compares an instrument's trading range for one day to that of the previous day. Positive directional movement occurs When today's high is greater than yesterday's, directional movement is positive (+DM). Conversely, when today's low is less than yesterday's, directional movement is negative (-DM). Based on the average of positive and negative directional movement over a certain time period, Two lines, +DI and -DI are plotted as averages of positive and negative directional movement over the defined time period. The +DI crossing the -DI is considered a buy signal when the +DI crosses in an upward direction and a sell signal when it crosses in a downward direction.
