Interface: SeededRecursiveFold ​

Defined in: indicators/src/kernels.ts:226

A Wilder recursion whose state starts at a constant and applies the recurrence from the first observation on — KDJ's K and D start at 50, so a first RSV of 80 reads K = (50·2 + 80) / 3 = 60, not 80. A null input (a gap, or a value that is not an observation) is no reading and leaves the state where it was — the recursion's memory is counted in observations, not bars, so a node built on it declares no lookback. A step that leaves the range is no reading and no state, like rmaFold's.
