Hopefully their scheduled Saturday update will help. For me - IBs API didn't return any new positions taken today in positions snapshots from open till close. That's some serious problem for automated trading and it is getting into a dangerous territory of broker bugs. Good I had coded a failsafe for this possibility, it was a close call though.. Im happy with IB otherwise. But there isn't much of an alternative for Canadian without getting into US LLC. Hopefully Alpaca happens, eventually. Val
I've gotten positions fine but historical data is broken and disconnections happened at seemingly random - I use sleep in code for minutes and afterwards when making a request for historical data I get error code 504 (not connected). Never had this happen but once before, now it's daily.
I suppose they get the "whales" by the word of mouth. Indeed if you take a lot of margin loans on large money, IB is a no-brainer. Their website is STUPID but eventually, you figure it out or some other trader shows you. If you tried to put a purchase of a house on margin IB has NO interest in you, they want you to TRADE up a storm and use margin, they are not realtors. Also, they are not for a serious investors either. They want traders =, bigger the better.
