This screen finds stocks whose 14-day ADX is above 25. The Average Directional Index, developed by J. Welles Wilder, measures trend strength regardless of direction, while the +DI and -DI lines show whether upward or downward movement dominates; readings above 25 indicate a strong trend. An ADX above 25 shows that the stock is trending strongly, the condition in which trend-following strategies work best; the DI lines tell whether the trend is up or down.
