Perhaps there ought to be a Sanity Clause to prevent envious kids turning litigious when they think they got a smaller pressie than other family members. But we know that wise St Nicholas would always prefer a red suit to a lawsuit and uses a clever technique to avoid arguments over equity and impartiality – applying a well recognised and altruistic benchmark called the Value Weighted Average Present (VWAP).
Those seeking a fair price in equity land often target the VWAP as a safe participation proxy which utilises the historical volume distribution curve as a guide.
At big xyt we agree that this is helpful and our team further realised that this volume curve should be broken down by mechanism (how are the shares trading?) and venue (where are the shares trading?) for each distribution bucket.
That helps us to understand the historical profile in more detail, but what is happening TODAY could be different, perhaps influencing how much volume we might want to reserve for the all-important closing auction.
The approach our team takes to normalise, cleanse and analyse the data can now be applied to real-time data feeds (not just to sackfuls of historical data processed overnight), resulting in the ability to draw today’s volume curve right before your very eyes.
In Chart 1 we see the historical average above the dynamic curve for today, each broken down by mechanism, whilst Chart 2 shows a similar comparison broken down by competing CLOB venues. Note: for good measure Chart 1 is tracking historical and realised volatility as well.

Incidentally (for those interested in venue time spent at CBBO), our T0 delivery also means we can calculate Presence in the present as well as in the past, and we may well roll it out for futures.
