Multi Charts and IQFeed Historicial Data

Henry,

Some questions about the Historical data from IQFeed;

* Last friday when the exchange data for ICE was incorrect, you deleted the symbols under ICE in the QM and then used the correct TimeZone. When I loaded the data for say @TFS# I noticed quite different performance results with my strategy. I had to retune my strategy to get similar results. Originally I think "Icelandic Stock Exchange" was selected rather than "Intercontinental , UTC-5".

* Did this change alter how the historical data has stitched together?

* Does MC control how historical data is stictched together based on this session info or does it come directly from IQFeed?

* For example @TFS# stitched historical data stitched together?

* What does "Merge data sources into a single chart" exactly do . It is available under FORMAT > Instruments

Hello Sir.
"Icelandic Stock Exchange" was the incorrect exchange.
I have renamed it to "Intercontinental". The correct time zone is UTC-5.
Historical daily data is received directly from IQFeed but the bar receives the time stamp according to the symbol sessions in Quote manager.
Merging is receiving real-time data and historical data from two separate data sources.

okay thanks - can you explain to me how the stitching of historical contracts is done e.g @TFS# - does MC do it or does it come directly from DTN IQ?

Continuous conracts like @TFS# are provided directly by DTN IQFeed.
