SC Team - Tried to use New Instance feature of DTC and few observations I have made and would like to provide some feedback in a new thread (as the main thread is locked). - I think "new instance" menu item should be disabled for all the sub-instances. If not the process would be sub-instance or a sub-instance (unless this is intended design). - data folders are different for each of these instances. I think this would contribute to redundant data being collected under various instances and not sure whether this is a good feature or not. Is this an intended design feature to have separate data folders for each instance? - One "convenience" of having separate data folders(Current design) is - one can have various versions of study dlls. If the design is to have separate data folders, there is no change needed here. But in case if the data folders gets shared from the main folder - it might be a good idea to provide a separate folder for study dlls - which would allow independent versions of study's to be run with individual instances.

Yes this was intended. The folders must remain separate. Otherwise, conflicts would arise.When a new instance folder is created, in the next release DLL files, Trade Window configuration files, and Study Collection files will be copied from the main instance.

If the data source being the same - would still cause a conflict? Would imagine collecting/storing the data multiple times(each instance collecting it's own data - potentially for the same instrument) - wondering if it an efficient use of resources. Probably - having one dedicated instance just to collect data for each required instrument ( intraday file update list ) - one would be able to collect the data - which can technically be shared with multiple instances generated from this same data source. I am pretty sure - you might have given sufficient thought to this already, but somehow think - collecting the data for the same instrument multiple times/same data source seems a bit unusual. Would imagine - data collection job to be handled just by the primary instance as a master. Technically this shouldn't cause any conflicts and let the sub-instances use the same data folder - but use this new instance core to perform study calculations. I think this would be a bit more efficient compared to the current implementation of having all the individual instances have their own data folders with same instrument data(potentially). thanks Date Time Of Last Edit: 2016-03-22 21:26:21

Yes, it would seem more efficient to share the data folder but that is not how it is done currently. There are various complications which would have to be solved first before allowing this. It is easiest for it to be completely separate. Do not expect any changes with this at this time. Sierra Chart Support - Engineering Level Your definitive source for support.

Thanks SC team. I was not actually planning on using multiple instances - but was merely providing a feedback based on observation as the concept is really good to share the load across multiple cores. Would certainly explore this again in the near future though. Thanks Date Time Of Last Edit: 2016-03-22 22:34:27

SC: sorry being a bit lazy here as I have not read all the documentation and threads about multiple instances. I am not even sure I understand why this is needed or how one benefits from it, other than perhaps the comment above about sharing the CPU load. But is this feature even available to me?? What I mean is I have a broker (AMP) supplied licence to SC, are traders such as myself able to use multiple instances through a broker supplied version of SC? |

For the typical Sierra Chart user, there are these benefits: -Distributing CPU load across multiple CPU cores if you notice the CPU usage of Sierra Chart is high based upon what you are doing. - Each Sierra Chart instance has its own main window which can be placed on a separate monitor in the case where you want to have groups of charts on different monitors and do not want to use the detached chart feature: https://www.sierrachart.com/index.php?page=doc/doc_DetachingandAttachingChartWindows.html The feature is available to you. However, wait until our next release coming out later today. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
