Directional Movement Index (DMI)
Candlefocus EditorThe two primary lines are the directional movement indicator (+DI) and the directional movement indicator (-DI). These two lines measure the strength of a price trend, with the larger the spread between the two indicating a stronger trend, either up or down. A +DI reading typically indicates an uptrend if it is above the reading of the -DI and vice versa.
In addition, the third line; the average directional index (ADX) has a non-directional element, measuring the momentum of a given price movement. The ADX can be used to interpret the “strength” of a trending move, with a reading above 25 typically indicating a strong trend.
It is important to note that, although the DMI can be a powerful tool for gauging trend strength and direction, it is not infallible. The indicator often generates false signals, and its accuracy increases when used in conjunction with other trending indicators such as moving averages.
Ultimately, the DMI can be an incredibly useful tool for traders looking to interpret the trend of a given financial asset. By providing valuable insight into both the price direction and momentum of a move, it can help inform savvy trading decisions.
