Is the trend strong or chopping? (ADX)
Separate a real trend from sideways noise before you commit.
Most indicators tell you a direction. ADX tells you something different and just as important: is there a trend at all, and how strong is it? It ignores up vs down — it only measures strength.
Reading ADX
- •ADX below 20 → weak or no trend. The market is chopping sideways; trend strategies struggle here.
- •ADX above 25 → a real trend is in force (could be up or down).
- •ADX above 40 → a very strong, powerful trend.
Why it matters
Crossovers and breakouts fail in choppy markets — and choppy markets are exactly where beginners lose money taking "signals" that go nowhere. ADX is the gatekeeper that tells you whether the market is even in a state where those signals work. A rising ADX means the trend is strengthening; falling means it is fading.
ADX gives you no direction on its own — combine it with price vs its moving averages (from the charts lessons) for that. ADX answers "is it trending?"; the averages answer "which way?"
Tip · Use ADX as a filter: only take trend or crossover setups when ADX is above 25. It quietly removes the whipsaw markets that eat trend-followers alive.
