Hull Moving Average
A weighted moving average already leans on recent bars more than an SMA, but it still lags the same way any moving average does. Hull's construction computes a WMA over the full period and a second WMA over half the period, takes twice the fast one minus the slow one, and runs that difference series back through a third WMA sized to the square root of the original period. The middle step is not cosmetic - it is what removes the lag - and the final smoothing pass is what keeps the result from being jagged. This is implemented as the literal three-stage formula, not an approximation: two calls to the platform's own iMA() in MODE_LWMA build the raw difference series, and a manually weighted sum over that series performs the final stage, because the final WMA is applied to a derived series that iMA() itself cannot see. Notes and limitations - Needs InpPeriod + round(sqrt(InpPeriod)) bars of history before the first value appears; earlier bars are intentionally left empty rather than guessed. - Less lag does not mean no lag or no false turns - the Hull line can still wobble in a choppy range like any short-period average. - Recalculated per bar from price directly, with no dependency on its own previous value, so there is nothing here that can repaint or drift.
