NT DMI Directional Movement Index
NT version of the DMI indicator.
This is one of the fundamental market indicators; it displays the direction and strength of the trend.
The DMI is somewhat similar to the RSI indicator by Welles Wilder. But, unlike the RSI that uses a fixed period, the DMI uses a variable period.
The indicator varies in the range of [-1; +1]. When the indicator value approaches its lower boundary, a downtrend is formed; when the indicator value approaches its upper boundary, an uptrend is formed.
