RSI
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: rsi
Exact formula
gain_t = max(C_t - C_(t-1), 0)
loss_t = max(C_(t-1) - C_t, 0)
RS = RMA(gain, p) / RMA(loss, p)
RSI = 100 - 100 / (1 + RS)
if RMA(loss, p) = 0 or is not finite: RSI = 100
Parameters, defaults, and bounds
- period : default 14 ; 2–100
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.
