What Is Minus Directional Indicator (-DI)
The Directional Indicator was developed in 1978 by J. Welles Wilder as an indicator of trend strength in a financial instrument’s prices.
Plus DI represents an absolute up movement, and Minus DI represents absolute down movement.
Here please note that “+” and “-” denotes only upward and downward movement. “-DI” is not a negative number. But a positive number of a downward movement.
The Negative Directional Indicator (-DI) measures the presence of a downtrend and is part of the Average Directional Index (ADX). If -DI is sloping upward, it’s a sign that the price downtrend is getting stronger. This indicator is nearly always plotted along with the Positive Directional Indicator (+DI).
-DI is a momentum indicator and is used to measure the presence of a downtrend. It is part of the Average Directional Index (ADX) along with +DI. The ADX reveals trend direction and trend strength.
How To Calculate -DI
Formula:- Directional Movement calculations are below. The moving average used is the one originally defined by Wilder is the SmoothedMovingAverage(SMMA)
- upmove = high – high(-1)
- downmove = low(-1) – low
- -dm = downmove if downmove > upmove and downmove > 0 else 0
- -di = 100 * SimpleMovingAverage(-dm, period) / atr(period)
Why Use -DI
-DI, along with +DI, was initially designed for commodities but is now used on all major financial markets. The indicator can indicate the market trend, and if the -DI moves up above the +DI, the price downtrend is getting stronger. On the other hand, when -DI moves down and goes below the +DI, the price uptrend is stronger. This can help traders enter and exit the market effectively.
How to Use -DI Trading Strategy
Bullish Scenario:- Since the indicator shows the strength of the downtrend, a lower -DI value will indicate a price increase, meaning a bullish scenario.
Bearish Scenario:- Similarly, in case of an increase in -DI will indicate a strong downtrend, thus leading to a bearish scenario.
