Positive Directional Indicator (+DI) A component of the average directional index that is used to measure the presence of an uptrend. When the +DI is sloping upward, it is a signal that the uptrend is getting stronger. This indicator is nearly always plotted along with the negative directional indicator. Investopedia Says: Many technical traders will watch for the positive directional indicator to cross above the negative directional indicator to signal the beginning of an uptrend. The +DI is a key factor in the calculation of the popular average directional index.
