I am hoping someone can give me some insights on what happened to my April CME puts I bought starting a little more than 2 weeks ago. I bought one April 370 put at 2.45, the stock has not moved since then and it's now bid at only 0.35. When it went down under 1 late last week I figured my analysis was still valid and I then bought one April 380 put for 1.10 in order to take advantage of the slightest correction in the coming days. Now the 380 put is at 0.75. I realized volatility has dropped from about 30% to 24% today since my first purchase . At the same time other exchange stocks have started to drop, especially today. But CME actually went up ! What is going on ? I still think CME could tank by expiration I don't see why those options are melting so fast, a couple of days theta was -0.9 now it's - 0.14 and -0.16, these option are losing 15 cents a day! That's ridiculous, there is one month left to expiration or maybe there is something I don't know. I am fairly new to options but I can say I have never seen an option go down that fast, I feel like I have been cheated.
