Data matches in all cases.


We did discover problem though that where after connecting to the data feed, there is not a historical data download for the symbols recording real-time data which needs to happen. This will cause a slight amount of data loss at the time of connection. We are fixing this now. We are not sure when this problem began to occur though. But it is not related to what you are experiencing.
