I have two copies of SC set up on the same computer. On copy (1), it is set up to connect to SC Data pulling in real time data. On copy (2), it is set up to connect to SC Data for historical intraday data (SC Data, allow Sierra Chart data feed off). Both 1 and 2 load multiple instances. What im expecting is the instances opened by their respective SC copies will stay on their respective connections. So if an instance is opened by (1), that instance will be connected to the real time feed. If an instance is opened by (2), that instance will be connected to the historical feed only. What i think im seeing is that the instances opened on (2) are connecting to the realtime feed of (1). Im saying this because the instances on (2) is running into the real time 750 symbol limit, which it shouldn't if its only connecting to the historical data feed. If i only load SC (2) by itself (which is processing about 1000 symbols), it will not run into this error. Can you offer some clarity? |

upon further testing, the connection for the first copy of SC that is loaded, is what all subsequent instances are using to connect afterwards. going in and trying to chnage the "allow sc data feed" setting individually for each instance has no effect.

This should not be the case unless they are using the same DTC protocol port number: What i think im seeing is that the instances opened on (2) are connecting to the realtime feed of (1).
