What it computes
A weighted mean of Widner’s ten rainbow averages of closes — each a Length-bar SMA of the one before — with weights 5, 4, 3 and 2 on the first four and 1 on the other six, divided by 20.
It describes bars that have already printed. QuantZ does not claim this indicator has predictive value, and it is not a recommendation to do anything.
Inputs and lookback
- Length · default 2
Reads open, high, low and close from the loaded bars. It produces nothing until at least 11 bars are loaded, a settling period no parameter shows.
What it assumes about the series
- Bars arrive oldest to newest at one interval, each with a finite open, high, low and close. The input is the chart’s loaded series, whatever its length.
- The function is given bars, not sessions: it does not know the timeframe, where a session opens, or that a gap in the tape is a gap.
- Warm-up bars are omitted rather than padded. The first value appears once the arithmetic has enough history, and nothing is drawn before it.
- The newest bar is the forming bar. Its value uses the live close and settles when the bar closes.
Whether a drawn value can change
forming-bar · Moves only on the forming bar. The newest bar’s value moves with its live close until that bar closes. A closed bar’s value is final and is not redrawn when later bars arrive.
This class is read from the registry entry and checked by a test against the function itself: for a class that says closed bars are final, appending a bar must leave every earlier point unchanged, and for a class that says they are not, it must not.
Outside its inputs
- Nothing outside the loaded bars: no longer history than the chart has loaded, and no other interval.
- Nothing inside a bar: no individual trades, no order book, no bid or ask.
- No other symbol, no benchmark, no news, no fundamentals, no earnings dates.
- Volume is not read at all.
