Broker not connected during algorithm initialization by Anne-Mirthe Stam

Hi, I am using the Visual Studio IDE to build some local testing.

I am using Interactive Brokers for paper trading. I am facing the following problem:

As far as I understand, first the Algorithm is initialized, then the engine will connect to the broker. however, in the algorithm initialziation, the 'AddEquity` method tries to load historical data from the broker connection. This will throw NotConnected errors, because the SetupHandler will only connect after the Algorithm has been initialized. Therefore, I will end up in the 60second timeout.

Am i missing something conceptual or doing something wrong? Thank you!

Basically it is the GetLastKnownPrice method fired by the security seeder that tries to connect to the broker api.

Looks like adapting the 'BrokerageSetupHandler' works. I have moved the 'connect to brokerage' logic to precede the 'Initializing algorithm' code. All unit tests are fine. Altough my problem might be solved I am unsure whether this will cause other problems. Any ideas?

Well, apparently it does generate problems, as the OrderProcesor has not been set when swapping the init order. :(
