Wilder’s DMI (MT4)

Wilder’s Directional Movement Index (DMI) plots +DI, –DI, and ADX to quantify trend direction and strength. This version adds clean coloring, alerts, and (optionally) arrows for MetaTrader 4.

What it shows

• +DI vs –DI crosses → potential bull/bear control shifts.
• ADX → trend strength (rising ADX = strengthening trend).
• Levels (e.g., ADX 20/25/35) to separate range vs trending conditions.
• (Optional) alerts/arrows — DI crosses, ADX rising/falling, level exits/returns.

Trade ideas

1. DI cross + rising ADX: enter when +DI crosses above –DI and ADX is rising above 20–25; mirror for shorts.
2. Pullback in trend: with +DI on top and ADX rising, buy pullbacks to structure; exit on DI recross or ADX roll‑over.
3. Range filter: when ADX < 20, fade extremes back to mean/structure rather than trend‑follow.
4. (Optional) MTF filter: only take M15 signals when H1 ADX rising in the same direction.

Inputs that matter

• Period — default 14 (Wilder); shorter → more responsive.
• Smoothing — average type for DI/ADX.
• Levels/alerts — DI crosses, ADX thresholds, slope states.
• Colors/widths — quick visual read.

Suggested usage

• M5–M15: DI crosses with ADX confirmation.
• M30–H4: trend pullbacks with ADX > 20–25.
• Daily+: bias map and strength gauge.
