nkhoi and brocklanders,
Thanks for the explanations, but I am not sure if you are saying the same thing using different terminology or not. I guess in my limited understanding I would like it to work as brock says it does, but I thought it required the steps nkhoi mentioned, which seem more involved.
Just to clarify what I mean by using the historical data at the same time as real-time feed... I mean data that is daily, weekly, etc. (i.e. daily OHLC charts for instance) not additional back-fill for the real-time feed. The backfill still is provided by the data provider (IB or TT as an example) and is limited to a certain number of days back. For what I do, the backfill is adequate and not worth me paying for unfiltered. The historical data I get from SC is limited to end-of-day data only.
You can setup a configuration that nkhoi mentioned that involves combining multiple real-time feeds and backfill from different providers but this requires the separate instances of Sierra Chart and is more complex. I have never tried this personally but I think others have it working well so I know it can be done.
Kiwi_trader I believe uses a similar type of setup to provide more accurate intraday OHLC bars in IB's feed but I'm not sure if it requires separate copies of Sierra Chart or not. He can explain better how he does this but it has something to do with combining IB's TrueLive feed with a 5 second feed for more accurate OHLC data.
edit: I found this post on Sierra's forum which explains a little more about kiwi's setup. It looks as though with a little effort this can be accomplished in a single copy of Sierra Chart.
