I heard most of the other major brokerages had issues at bell (server overload). Curious to hear how TWS executed?
The IB datafeed is snapshot multiple times per second instead of tick by tick. This means when other brokers are having problems then IB should work. IB did have problems a few months ago when Tesla broke higher and everybody was looking at it. This problem seems to have gone away. Not sure about this morning though.
My automated executions at IB worked flawlesly opening 8 positions within first 15 seconds. The thing didnt go thru is a short of UAL. I'm yet to dig down to the reason, perhaps it was unavailable for short at the time. Val
