Today one of my IBKR-linked strategies tried to submit an order for TEL1L:LTU, but the order was rejected from IBKR with an “Unknown Contract” error. I do see the security when I look directly on IBKR, so I’m guessing there may be an issue mapping securities for Lithuanian stocks – I believe this is the first one its attempted to trade.
I've just changed the configuration on our end to use direct order routing for NASDAQ Vilnius. Let me know if you still see order rejects.
Thanks for the quick fix, Aaron. I was able to submit an order and get filled on that ticker today.
