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: smi

Exact formula

HH = max(H, p); LL = min(L, p)

raw = 100 * (C_t - (HH + LL) / 2) / (HH - LL)

value = SMA(SMA(raw, smooth), double_smooth)

if HH = LL: raw = 0

Parameters, defaults, and bounds

- period : default 14 ; 2–100

- smooth : default 3 ; 1–20

- double_smooth : default 3 ; 1–20

How the rule passes

above requires a strict > comparison.

below requires a strict < comparison.

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.
