Came across this thread today from a discussion on another forum.
Hi @PravinJ
in the detailed analysis shared above,
what happens in the scenario when this detailed Risk & Order Validation phase
(that is executing in parallel to the Order Submitted to Exchange phase )
returns an error i.e. order fails validation.
Now what happens to the order recently submitted to the exchange?
Do you mean the prder is initially submitted to the exchange,
but it is NOT allowed to be filled until the internal detailed validation is successful?
