These changes are required to connect and receive data properly since the TLS 1.2 server upgrade on 6/16/2019. This also required upgrading the IKVM libraries for C#/Java interop.
When selecting IEXDataQueueHandler as a data source for live trading,
it would not connect. The following fixed the issue:
- Updated Socket IO NuGet package (and its dependencies) to latest;
- In GzipStreamProvider, removed obsolete "using" statement refering
to deprecated Socket IO API (using statement was not used anyways);
- Increased the reconnection delay value to its recommended
value (1000ms), this was necessary for the feed to connect;
- Minor change in IEXDataQueueHandler to parse Json message.
"(JObject)message" would compile, but threw a runtime error, as this
formulation could not implicitly convert string to JObject. Used
the cleaner "JObject.Parse()" method instead.
In the advanced build settings, Language version was also upgraded from C# 5.0 to C# 6.0. The minimum Visual Studio version required will now be VS2015.
