The DI+ and DI- line move away from each other when price volatility increases and converge toward each other when volatility decreases. Short-term traders could enter trades when the two lines move apart to take advantage of increasing volatility. Swing traders might accumulate into a position when the lines contact in anticipation of a breakout. Traders could enter a long position when the DI+ line crosses above the DI- line and set a stop-loss order under the current day’s low, or below a recent swing low. When the DI- line crosses above the DI+ line, traders could place a short position with a stop above the high of the current day, or above a recent swing high. Traders could use a trailing stop if the trade moves in their favor to help lock in profits.

For example, if the +DI line crosses above the -DI line and the ADX is above 20, or ideally above 25, then that is a potential signal to buy. On the other hand, if the -DI crosses above the +DI, and the ADX is above 20 or 25, then that is an opportunity to enter a potential short trade.
