What it does
Exponential VWAP puts more weight on recent volume than older session activity, so the line responds faster when intraday conditions change. It works best as a quicker fair-value reference alongside price structure or participation tools.
Who this is for
This page is aimed at traders who already know what problem Exponential VWAP is solving and want clearer notes on setup, tradeoffs, and platform coverage.
Key terms for this tool
Review the core trading and platform terms tied to this page before changing settings or using the study in a live workspace.
What it is not
Exponential VWAP is a chart-context tool. It does not place trades, manage risk automatically, or promise that a specific pattern will resolve in one direction. Use it to organize decisions, not to outsource them.

Inputs: Decay(0.94);
Vars: EWPriceVolume(0), EWVolume(0), EVWAP(0);
If Date <> Date[1] Then Begin
EWPriceVolume = TypicalPrice * Volume;
EWVolume = Volume;
End Else Begin
EWPriceVolume = EWPriceVolume * Decay + TypicalPrice * Volume;
EWVolume = EWVolume * Decay + Volume;
End;
If EWVolume > 0 Then EVWAP = EWPriceVolume / EWVolume;

- Requires reliable volume data.
- The faster line can create more false context shifts.
- Session reset rules matter.
