What it computes
The mean typical price of every loaded bar, drawn as one level across them.
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
No parameters. The construction is fixed.
Reads open, high, low and close from the loaded bars. The first value appears once the longest lookback its parameters name has elapsed; earlier bars are left empty rather than padded.
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.
- It is the LOADED average, not the visible one: the chart hands every indicator the whole loaded series, so zooming does not move it and a new bar moves it everywhere.
Whether a drawn value can change
trailing-anchor · Recomputed from the newest bar. The line is derived from an anchor measured back from the newest bar, so the values on closed bars are recomputed every time a bar arrives.
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.
