DMI

What SteadyEdge calculates

This page documents the exact runtime calculation for the listed filter IDs. Formula symbols use O , H , L , C , and V for the current candle open, high, low, close, and volume; p is the configured lookback.

- Registry filter IDs: dmi_plus , dmi_minus , dmi_spread

Exact formula

TR = max(H-L, abs(H-C_prev), abs(L-C_prev))

+DI = 100*RMA(+DM,di_length)/RMA(TR,di_length)

-DI = 100*RMA(-DM,di_length)/RMA(TR,di_length)

spread = +DI - -DI

Parameters, defaults, and bounds

- di_length : default 14 ; 1–100

How the rule passes

above requires a strict > comparison.

below requires a strict < comparison.

cross_above requires the previous value below the threshold and the current value at or above it.

cross_below requires the previous value above the threshold and the current value at or below it.

Data, timing, and warm-up

Candle filters use the rule timeframe and the latest candle at or before the evaluation time. A non-finite calculated value does not pass.

Every rule in the same filter set must pass. Test Filters and a backtest validate the complete set.
