If the system was not counting its trades, would they show up in the dashboard? A reconciliation would be necessary, which would come from where the orders were being sent to (the exchange), but with millisecond delays a realtime dashboard seems only necessary for this case (not that it is a bad case) and while End Of Day reconciliations are needed, I'd be interested if anyone knew of exchange requirements for intra-day trading reconciliations?
