# forge.ta.dmi

```python
forge.ta.dmi(high: ArrayLike, low: ArrayLike, close: ArrayLike, period: int = 14, method: str = 'mt5') -> dict[str, np.ndarray]
```

Directional movement: ``plus_di``, ``minus_di`` and ``adx``.

``method="mt5"`` is MetaTrader 5's ADX (``2 / (period + 1)`` smoothing seeded at zero; every
line starts at bar ``period``). ``method="wilder"`` is Wilder's original (``1 / period``
smoothing seeded with plain means; the DI lines start at bar ``period`` and ADX at
``2 * period - 1``). Where the true range is zero the lines read 0.

## Class forge.ta.DMI

```python
forge.ta.DMI(**inputs: Any) -> None
```

Trend direction as two lines, with the strength of the trend.

TR = the true range, +DM and -DM = the larger of the two directional moves, the other is 0

+DI = 100 * smoothed(+DM) / smoothed(TR), -DI = 100 * smoothed(-DM) / smoothed(TR)

DX = 100 * |+DI - -DI| / (+DI + -DI), ADX = smoothed(DX)

mt5: smoothing with 2 / (period + 1), starting from zero. wilder: smoothing with 1 / period, starting from the mean of the first period values. Where the true range is zero the lines read 0.
