ADX fluctuates between 0 and 100. Readings below 20 indicate a weak trend or ranging market and readings above 40 indicate a strong trend. ADX does not indicate direction but rather just the strength of the trend, up or down. |
Often plotted with ADX are two lines that indicate direction. The lines are +DI and -DI. If the +DI line is above the -DI line, then the trend is considered bullish. Crosses of the +DI and -DI lines generate buy and sell signals. For example, if +DI crosses above -DI, then a buy signal is generated.
