Using 1631 Using SC Data for real time data and CQG DTS with "Connect to Market Data Server" set to true (because of options data). Charts are set to use "Combine Trades Into Original Summary Trade" Could it be there is a bug when using a second instance of SC with DRC Sub Instance? Behavior: the data of the second instance seems to be different, different ask/bid volume for certain trades than the data from the main instance which gets its data from SC Data ([M]). There is no [M] on the chart of the second instance, but I assume that is normal. Allow Support for Sierra Chart Data Feeds" is enabled for the second instance as well. Means of testing: same symbol, same session times, time zone, intraday chart, filter trades of volume <= x completely (x doesn't matter), basically everything is identical across the two charts in the two instances. Then add a Cumulative Delta Bars - Volume study with Reset at Start of Trading Day. Now compare the close value at the end of the day across the two instances. The main instance might show something like 6000 where the second instance shows only 150. Common theme across all symbols, the second instance has much smaller numbers. If I "Delete and Download Data" in the second instance, the numbers from above are perfectly in sync across the two instances. Tested this behaviour with many Symbols. Could it be the second instance doesn't get the data from SC Data but rather from CQG, and only upon deleting the data and redownloading it do I get the data from SC Data?
