Starting today, I get the order confirmation / check margin impact window popup when clicking Buy or Sell in the integrated stock trading window. Window has no error or warning messages. I used the exact same setup for 2 years daily, didn't change any configuration setting whatsoever, never got an order confirmation window. After starting TWS today I get this stuff; checking the Armed checkbox doesn't help. Clicking Buy or Sell in the Portfolio window doesn't result in the popup; it's only when trading in the Integrated Stock Window. Configuration -> Messages -> Confirm Order Submission is unchecked. I'm on TWS stable version. It is impossible to do my volume of trading when I get a popup for every order. Please help.
Check your Config > Presets > Stocks > Size > "Quantity" (set to shares, not dollar amount) It is likely set to 1000, or something lower than what you are try to trade with.
No. I reported the issue with their latest revision of TWS stable version; they confirmed the problem.
