This just happened to me, and I now have negative excess liquidity. No options expired today. Has anyone else experienced the same? Edit: Might be related to TQQQ splitting, since that's the only change I notice.
In which instruments do you notice a margin increase? Stocks, ETFs, futures? Limited to specific tickers, or for everything?
Stocks and ETFs. But, yeah, it's due to the stock split. The extra contracts haven't shown up yet but the price halved. I'll leave this thread up in case anyone else experiences the same problem.
This thread is posted in the Interactive Brokers section of the forum, so I was assuming that the question was about IBKR.
