TWS connectoin is broken

jzshen · Jun 28 2024

I'm using MC with IB TWS. Starting from this week, parts of the TWS connection do not work. In details, DOM works, but charts on continuous future contracts are broken. Those charts cannot be backfilled or reloaded. Moreover, from TWS side, I can see lots of connection attempts are dropped. Same setups do work before, and MC.net does not have this problem.

Any idea on how to fix it?

Thanks

Update: MC.net also affected after restarting TWS.

It seems the latest TWS 10.30.1d caused the problem. After downgrading to 10.19.2o, MC and MC.net work again. I have no idea what changes under hood, but this could mean that MCs require updates soon.
