Elastic Volume-weighted MA

Elastic Volume-weighted MA runs Christian Fries' recursion, in which volume rather than time decides how fast the average moves: each bar rewrites a share of the line equal to its volume divided by a budget N: heavy bars relocate the line, quiet bars barely touch it, zero-volume bars leave it unchanged. It implements the elastic volume-weighted moving average with both budget conventions plus an optional slower pair line, a comparison EMA and a stretch read.

How to Trade the Elastic Volume-weighted MA?

• Slope color: the participation-weighted trend read — only volume-backed moves turn the line quickly; slope reversals are alertable.
• Price side and crossings: the standard bias read against a volume-aware baseline, alertable with optional markers.
• Pair crossings: the optional fast/slow pair runs on one volume clock, so thin-trade drift struggles to trigger crossings.
• Stretch beyond the threshold: with a float budget the line approximates the holder base's average entry, so a stretch flags large open profits or losses — context, not timing.

Elastic Volume-weighted MA Settings

• Source (default close).
• Volume Budget (N) (default Cumulative Volume (Lookback)): Shares Outstanding (Float) uses the float instead, with an automatic fallback where share data is missing.
• Budget Lookback (default 20): bars of volume summed into the cumulative budget.
• Budget Multiplier (default 1): scales the summed volume; ignored in float mode.
• Second eVWMA (default disabled) with Second Budget Multiple (default 4): the slower half of the crossover pair.
• Comparison EMA (default disabled) with EMA Length (default 39): a matched-speed conventional average.
• Stretch Threshold % (default 10): the distance beyond which the stretch alerts fire.
• Show Dashboard (default enabled); Slope Trend Coloring and the gradient fill default on, Price Crossing Markers off, Line Width 2.

Frequently Asked Questions

How is the eVWMA different from VWAP?

VWAP averages every price traded since a fixed anchor and resets when the anchor does. The eVWMA has no anchor: its memory is a rolling volume budget, so it never resets and keeps adapting bar by bar.

What does the dashboard's Bar Weight mean?

The latest bar's volume as a fraction of the budget — literally the share of the line that bar rewrote. A 10% weight moved the line a tenth of the way to that bar's price.

Which budget mode should I use?

Cumulative Volume works on any symbol. Shares Outstanding follows Fries' original proposal, turning the line into an approximate cost basis for the holder base — most meaningful on equities with reliable float data.
