Summary
I have been in the sidelines during this month waiting for the rally to weaken and IV to increase, as I have had a couple of bad experiences selling Credit Call Spreads in that environment and selling Put Spreads seemed to be a bit suicidal too.
Now the correction is here, but it has arrived stronger that expected, both in Europe and USA, so I decided to go for a 12100 - 11700 Put Spread for February and not March.
Next week, we should have better visibility on the size of the correction and I might dare opening another Put Spread in March.
