I don’t but it’s very peculiar. The 200,253 sell order @ 6.8 was placed at the same time as your buy (almost certainly by your same broker), assuming you’re in the bunch that traded at that time. The price post trade ended at 7.1c. Had the sell order not been simultaneously placed, the market price would have finished at the same price of 7.1c, but your average fill would have been just under 7.1c.

Either you’ve got a broker who loves you, or it’s VWAP control as you say. Can’t see any other reason they would give you a better fill and end up on the same price.
