Is it possible to do this in the following way by setting two instances of sierra chart? 1. Set Up the Live Data Instance (CQG) 2. Set Up the Historical Data Instance (DTN IQFeed) 3. Sharing or Integrating Data Between Instances to combine historical data from the IQFeed instance with live trading charts from the CQG instance, which approach would be better ?: Using the DTC Server: Sierra Chart supports the Data and Trading Connectivity (DTC) protocol. You can designate one instance (for example, the DTN IQFeed instance) as a DTC server and have the other instance connect as a client. To set this up, go to Global Settings → DTC Server Settings in the instance you want to act as the server, configure it, and then connect from the other instance via Global Settings → DTC Client Settings. This enables real‑time sharing of historical (or even live, if needed) data between instances. Manual Export/Import: Alternatively, you can export historical data (e.g., via CSV export) from the DTN IQFeed instance and then import it into charts in your CQG instance. This method is less dynamic but can be useful for backtesting. |
