IB home page said intraday margin is $10,000, but when try to place an order, TWS say margin require $100,000.
When I go to place an order with 885 it says initial margin 12,162.96 and maintenance 9,733.64 which I believe is correct.
I think it's the front end. It crashed earlier. Everything works fine now after uninstall, reboot, and reinstall the front end.
