Quote from adam772:
Anyways, I had a bunch of credit spreads on and didnt realize a dividend was coming on a bunch of them. To be specific, I was short 50 of the SPY calls, 40 of the DIA calls , and 38 of the QQQQ calls going into expiration friday.
The short calls were all exercised Thursday evening cause of the dividend...I woke up friday to find myself long 5000 SPY, 4000 DIA, and 3800 QQQQ. Not a pleasant morning...
I couldn't sell out the position. Had to call ameritrade customer support. they couldnt even sell out the position.. they had to get margin on the phone, who finally gave the OK to clear out the position.
