ADX - Average Directional Movement Index (MT4)

ADX measures trend strength on a 0-100 scale while +DI and -DI show directional pressure. Rising ADX means strength is building whether the trend is up or down. Use crossovers of +DI and -DI plus ADX slope to filter entries on MetaTrader 4.

What it shows

• ADX: trend strength. Typical thresholds: 20-25 start of trend, 30+ strong.
• +DI and -DI: buying vs selling pressure. Crossovers hint at control changes.
• ADX rising: strengthening regime. ADX falling: consolidation or fade.
• Optional alerts on DI cross, ADX threshold cross and slope flip.

Trade ideas

1. DI cross with ADX rising: buy when +DI crosses above -DI and ADX rises from below 20-25. Opposite for sells.
2. Trend add: in an established move, add while ADX keeps rising and pullbacks hold structure.
3. Range filter: avoid breakout trades when ADX is falling below 20.
4. Multi TF: require higher TF ADX above 20 and DI alignment for lower TF entries.

Inputs that matter

• Period (classic 14) and smoothing method (Wilder by default).
• Price source for true range and DM calculation.
• Alerts for DI cross and ADX levels.

FAQ

Does it repaint? No on closed bars.
Why can ADX rise in a downtrend? It measures strength, not direction. Direction comes from +DI and -DI.
Use in EAs? Yes, via iCustom.
Markets? FX, indices, metals, crypto - anything on MT4.
