and all my charts revert to Historical from Intraday when I open SC unless TWS is open beforehand.
This totally makes no sense to us at all. This should never happen and we do not know of any technical reason why this would happen. Unless the charts are being referenced by another Historical chart, which is explained here:
Unable to Change the Bar Time Period for Charts


My chart settings are set with the SC Data symbol (ESH17 for example) and the "Trade and current quote symbol" is set to that of IB (which I thought was the proper way to do it
Do not do this. This is definitely the wrong way. The right way is described here:

So my question is, is it necessary to open TWS at all times while running SC, even though the data is still coming from SC Data?
If you require real-time data, then yes it is necessary to connect to Trader Workstation. Otherwise, the historical data should download when the Chartbook is opened.
