When subscribing to a contract -- either with Subscribe, SubscribeTicks, or SubscribeDOM -- how can I know if I was successfully subscribed to the contract or not?

If data are available - you will receive an update. If you subscribing too many contracts - you will get an error.
There is no other indication.

I assume you mean I will get an error with the OnError callback. Is there any way I can match an error in OnError with a particular subscription or contract? I need to know when I've failed to subscribe to ticks on a contract so I can continue to do proper data processing.

unfortunately, there is no connection between error and request available now.
