Auto Reconnect when TWS Restarts

[msacs09]

Folks,

Can anyone shed some light on how we code for auto reconnect, when TWS clients disconnected, effectively ending our API connectivity. Currently I need to restart my BOT daily when TWS restarts. I was wondering if anyone has done a similar code where it checks like heartbeat and reconnect, so that I don't have to restart my BOT every day when TWS restarts. I'm not sure if IB_Insync has any function out of the box?

Many Thanks

I'm not sure about TWS, but the standalone gateway has an auto-restart time you can configure under menu options Configure -> Settings -> Lock and Exit -> Auto restart. The built-in auto-restart even caches your 2FA session for a week when it restarts (as long as your IP address doesn't change between runs).

For the ib_insync client, you can add your reconnect method to the disconnectedEvent event so ib_insync will automatically re-establish the connection after gateway restarts (and a gateway restart is different than the nightly "system reset" where your connection remains active but the IBKR system goes offline and terminates all data feeds for 1-3 minutes).

I use the disconnected notification event like:

ib = IB()
ib.disconnectedEvent += lambda: asyncio.create_task(reconnect())

where reconnect() is an async method running your ib.connectAsync() call and any other setup required like re-subscribing to quotes/feeds/updates.
