Ianbeej,
The broker does have to report the small fills as part of the regulatory requirements for trading - all trades need to be reported to the market within 10 or 15 minutes of each fill (I think from 2020 it is 10 mins), hence the practice of cancelling and rebooking at end of day for the total amount.
Mirasol is right in that it is a small size, so maybe they are able to generate a single order if they are not too bothered about price. Yesterday was a very low volume day.
Bridge, I did state in my post that this was my opinion and what I outlined is standard dealing practice for vwap trading. I also stated the possibility that it could be a negotiated trade, so it is possible that one or either method is used, depending on how the buyer/seller and dealer want to manage the trade. The former is the most practical method of ensuring you stick to the vwap, especially if you are interested in the price obtained.
We often have days of lots of small, regular fills that make no sense, followed by a large trade at end of day. Yesterday may have been different in that regard, I did not pay attention to the trades throughout the day. Also, if you are going by the blue/red indicator shown, these are an indicator only, not the true direction of the trade, so it could be misleading.
