Here are my follow up questions and the answer from IB: XXXXX 2023/10/09 12:00:30 What is the latest time that the counter party could decide not to exercise an ITM option? And what is the earliest time I (the short position holder) can be notified that I would be the victim? XXXXX 2023/10/09...

Yes. You can think this way: my portfolio had only -10 such naked options. After the market close, I expected it would bring me -1000 stock so I bought stock out of the regular trading hour. At the end of Friday my porfolio was with +1000 stocks and -10 ITM options. But on Sunday I found the...

since you provided very helpful information in the previous reply, may I know what evidence can I provide to convince you?

Thanks. But what is SCHW? do you mean interest is also determined by P&L? I created ticket to ask CSR to explain the numbers in my statement. But no response for weeks.

assuming my total equity is $100k. I have short position of -$50k and cash +$150k.the current daily interest rate is 0.01%. How much would the Interest Accrued be for one day? I though it would be $15 (without including short borrow fee), right? But the number shown in my statement is negative.

My application uses the event updatePortfolioEx after call to IBApi.EClient.reqAccountUpdates periodically to fetch the portfolio changes. However I found it not very timely reliable, especially after a few hours running since TWS launched. Quite often my application won't get updating after the...
