I had long June SPY 119 PUT options and short June SPY 114 PUT options today, and they were liquidated during the volatile trading period. They were liquidated at the time when SPY was trading at 110-111. Simple math tells me that at the very very least, my 119 PUT options should be worth $8 - $9, since a put option gives me the right to sell SPY at 119, and given SPY being at 110-111 at the time, this option should at least be worth $8 - $9 (which should be much more, given the volatility and time value). I was liquidated at $5. My 114 short puts were liquidated at > $8. First of all, my PUTs were evenly hedge, so every point lost by the 114 short PUT in the falling market is gained by the 119 long PUT. So why was I liquidated by Interactive Brokers?? Also, the prices were unreasonable as explained above, which caused me losses in the 5 figures. How should I get this compensated?
