Hi All,
Scenario:
If client xyz sends an order to broker ABC and in reply to that the broker send around 15 fills to complete the order and then the broker wants to bust the 7th fill as the price was incorrect.
Question:
To bust the 7th fill would he need to bust all the subsequent fills as well ?
If No - wouldn’t that affect the avg price of all the subsequent fills ?
If Yes - Why ?
Thanks

Busting a fill has no impact on the validity on other fills. Some might reinstate the portion of the order quantity that was busted but it is rather unusual.
You are correct about the average price in that it will be affected. However, it is the average price of ALL fills on this order SO FAR. The fills 8-15 that were previously sent are correct as they gave you an average price under the assumption that fills 1-7 were valid. ExecutionReports are snapshots in time with respect to the average price. Busting fill 7 leads to an ExecutionReport referencing the order as well as fill 7 and can hold the new average price calculated from fills 1-6 and 8-15.
I do not see a reason to resend fills 8-15 with ExecType=G=Trade Correct. The average price is related to an entity (the order) and not a message (the ExecutionReport).

Hanno.

If you are a broker taking a DMA order then reinstating the busted trade qty might be unusual but if it is an algo or care order then it is normal practice.
