Wrong FIX implementation on cTrader server side

Hi ctid692448,

We consider our implementation correct. Business Message Reject is sent because the order validation fails. You will receive the same message if for example you pass a non existent symbol. We do not event attempt to execute the order, hence you cannot receive an Execution Report. The order cannot be rejected because it is not a valid order, the message is nonsensical.

Thanks for answering. It is bad practice because it is not according to FIX standards.

Good practice would be:
Not attempting to execute an order = not executing an order -> sending an order execution with a rejection of the order containing the reason for the rejection.

Please have a look at the link I posted above and scroll a bit down:

There it is extra stated that a business rejection message is not the right answer to a new order single. Please consider making the developers life easier by sticking to broad spread FIX rules being applied by (almost) everyone. You would also do a favor to yourself as a easier to implement cTrader FIX protocol will cause more people using it.
