In my case... I thought they were selling one... And they held it for a 6 days. Before selling. I didn't mind riding the market with one contract... And thought they would sell one automatically at 4pm.lile my tradestation account would. Instead they did nothing... And then waited for the market to peak and sold both for a massive loss... I was able anticipating the market to go up/down anyway... and long over time... Which it has been... But they waited forever, then sold at the exact worst time.
I thought for sure they were required to sell... Otherwise it's just regular margin, not day trade margin. Seems really strange to have something called day trade rate listed from 8am to 4om and let it be held for 6 days.
