How do I auto reconnect on disconnect?

I’m trying to call ib_insync.Client.connect(…) in a loop with a delay in wrapper.apiEnd and got an exception

RuntimeWarning: coroutine ‘Client.connectAsync’ was never awaited`

Is this the correct way to reconnect? Or do I need to del my client instance and create a new one?

Sorry for commenting on a closed issue, but I wanted to share a solution.

If peer closes connection (TWS being shutdown), you can catch this using the disconnectedEvent. Then you will need to break the run loop. Instead of dealing with async, I use a simple SIGINT signal for this. The program also needs to know whether if we are restarting due to a disconnect issue, or the user just wants to stop the program. This is why I set a class variable called reconnecting to True if our SIGINT’s intention is to reconnect. This way, we know if we want to stop retrying and exit to program.

If TWS loses connection to internet temporarily, then reconnects to market data (errorCode = 1102), we need to handle this inside errorEvent. I just set reconnecting to True, call disconnect() and raise SIGINT. If you dont’ disconnect, reconnect will not succeed due to clientId = 1 still connected.

If we lose connection to TWS due to API being disabled (errorCode = 1300) we need to set reconnecting to True, call disconnect() (might not be needed but it is idempotent) and raise SIGINT.

After doing all of this, there is still a problem. If I login from another computer, then logout, we still need to manually click the “Reconnect this session” button of the modal dialog that appears in the TWS application.

The assert is only hit in the case of nested event loops. To allow nested event loops, use util.patchAsyncio().
