Post From: Notice: Transact Websocket Connectivity Issue

You are not alone. Many Transact customers feel the same. The worst part of this situation is that Transact completely refusing responsibility for this issue and pointing to Sierra. This is a silent push by Transact to force people switching to their new platform. They going to start losing business and customers in droves pretty soon.

There are couple of basic issues here. One issue is lagging data and lagging data is almost always going to be an external cause. Refer to help topic 4:
Prices / Data Falling Behind

This is why we switched to the Transact compact JSON encoding but as of yet, they have not yet released that on their production server. We hope it will be this week.

The other problem is various websocket framing related errors. In the more than seven years or so that we have worked with websocket connections we have never seen any problem like this from a server.

If the issue is on the Sierra Chart side, it would be somewhere within the network I/O, encryption/decryption, Websocket framing layers or components. There is 0% chance it is at the network I/O or encryption/decryption layers. That is used extensively with all services including on our servers and that handles easily hundreds and hundreds of gigabytes a day flawlessly for years without any problem. There just is not a problem on our side there at all.

And with the websocket framing functionality, that is extensively used by CQG with 0% incidents like this ever over a period of at least five years. Although we are not sure we ever got frames larger than 65K from CQG and we do not know if that occurs with Transact either. However, we examined that code quite closely and see no problem. We also did a very thorough manual code review of the websocket functionality in Sierra Chart and see no problem.
