Betfair don't timestamp the traded volume in the data that can be downloaded from the API, so you'd need the ability to checkpoint the volume ladder at a specific point in time (triggered as a rule I suppose) and calculate the VWAP as a delta to that.
You'd only be able to store one checkpoint for the selection (each checkpoint would overwrite the last). If we allowed a ongoing sliding timewindow, the amount of data required to be stored would soon mount up.
At what point in time before the start of the race would you considering checkpointing? Not that it really matters as it'd occur when the rule triggers, but you'd have to ensure the rule could actually run and wasn't limited by restricted refresh. You could trigger based on a market volume condition if required... again as long as the market was allowed to refresh so that the volume could be tested.
Anyway, yes it's possible (as a single checkpoint), but it'll need some +1s as there's a bit of complexity to overcome.
I am +1 on an adjustable VWAP initiation point in time!
