I guess they will just state what I can see myself. IV increased from 50% to 370%. But how this is possible is still beyond me, specially when underlaying futures contect only went up a few %, no options transactions were done today in this options chain.. I mean if anything this is now the huge oportunity for you guys. If anyone can sell 20 put on CL for 5.000 USD as it is now prices, why not.. And hedge it with feb or apr options which trade for 2.000 USD on the same strike.. Beyond bizare.. I doubt anyone can make a trade at this price because I think this is some mispricing and since no trades were done today on this option chain they can price just anything they wish I guess.. But this then leads to hugee manipulations.. Like I said, someone then can just say IV is now two milliions, oh look no one has enough margin, liquidate all positions then lower IV back to 50... I mean who determines IV anyway? Is it not done automaticly by model? Or are market makers responsible for this?
