Weighted Price Composites
Every strategy that wants "typical price" or "weighted close" ends up writing the same three-line formula in a dozen different files, and a genuinely custom weighted blend - for example, a trend filter that wants the close weighted five times heavier than the wicks - is usually skipped entirely because it means yet another formula to keep consistent with the rest. This library collects the four common composite kinds behind one enum and one function, PriceCompositeGet(), plus a separate PriceCompositeGetCustom() for an arbitrary caller-supplied weighting of Open/High/Low/Close. Weights passed to the custom function do not need to sum to 1 - they are normalised internally, so "2, 1, 1, 4" and "0.25, 0.125, 0.125, 0.5" produce the identical result. A non-positive weight sum (all zero, or a caller mistake) falls back to the plain typical price rather than dividing by zero. Notes and limitations - All four built-in kinds and the custom blend read historical O/H/L/C via iOpen/iHigh/iLow/iClose - they do not access tick-level Bid/Ask, so shift 0 reflects the current, still-forming bar exactly the way any other bar-based indicator does. - The custom blend's normalisation only guards against a non-positive weight SUM. Passing one large weight and three zero weights is valid and simply returns that single price component - it is not an error. - No smoothing or averaging across bars is applied anywhere in this library; every function reads exactly one bar's O/H/L/C. Combine with a moving-average call if a smoothed composite is wanted.
