ADX

Measures how strong a trend is, not which way it goes. High readings favor trend trades.

About

The Average Directional Index (ADX) measures trend strength, not direction. It is built from +DI and -DI. Readings above 25 usually mean a trend is in force. Readings below 20 usually mean chop.

+DI above -DI with a rising ADX supports a long-side trend filter. The reverse supports a short-side filter. ADX alone does not say which way to trade.

Use ADX in a mix to allow trend-following entries only when strength is present, or to block mean-reversion entries when ADX is already high.
