EMA Crossover

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: ema_crossover

Exact formula

EMA uses alpha = 2 / (p + 1); before the full seed it is the running mean

value = EMA(C, fast_period) - EMA(C, slow_period)

threshold = 0 (fixed)

Parameters, defaults, and bounds

- fast_period : default 9 ; 1–100

- slow_period : default 21 ; 1–200

How the rule passes

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.

eq passes when the absolute difference is less than 1e-9 .

The threshold is fixed by the implementation and is not editable.

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.
