They really do not need to involve us in this, unless there is some change in the protocol. We have not heard from them regarding this. However, we have made it clear to Transact, that Sierra Chart has very efficient and well designed receiving and processing of the data. Yes switching back to 1941 is a temporary solution.

And just for the record, the same network communication core which is used in every installation of Sierra Chart is what is used on our server for transmitting historical data to users and real-time data. And also processing high-bandwidth exchange feeds which can be up to 70,000 symbols. It is a very high performance multithreaded network component which can easily handle data rates of a gigabit per second. If this were a client-side problem, when you notice to Transact feed is lagging, just simply see if Sierra Chart is responsive. If it is, then there is no abnormal load within Sierra Chart. And even if there is an abnormal load, it really does not cause the data feed to lag within Sierra Chart beyond a couple of seconds.

Perhaps I have not been clear enough in description of the Data lag problem. I apologize. Sometimes during periods of rapid movement. The Transact Dom is not lagging, but the charts themselves are lagging and by more than a few seconds. Then occasionally If I compare the chart from another platform,the SC chart will not display the entire move after catching up to match the Transact DOM displayed price, so I have to delete the .scid file for that symbol and reload the chart to represent what had actually occurred. So if the charts are lagging and not the Transact DOM, is that still a Transact/infinity issue or SC issue? Thank you |

Yes it is a Transact issue. The following message was sent to Transact earlier today: we continue to hear users who are having lagging problems and it looks poorly for us because they are not seeing the problem with your software and that would be because I think your software is still using the binary feed and using UDP from what I understand.
I think that providing market depth data in the JSON messages should be optional. And then we can give the user an option to turn off the depth. ,the SC chart will not display the entire move after catching up to match the Transact DOM displayed price, This is because after the send buffer on the Transact side, reaches a certain amount (We think 1 MB from memory), they just discard it. They did tell that to us. We told them instead they should close the connection and then when Sierra Chart reconnects, the missing data will be downloaded.so I have to delete the .scid file for that symbol and reload the chart to represent what had actually occurred.
You only need to follow the procedure here in this case:Historical Intraday Data (Missing Data / Download Errors / Viewing More Data): Retrying the Download When There is Data in the Chart Sierra Chart Support - Engineering Level Your definitive source for support.
