Heres where I come in with another episode of how to safely pick up pennies in front of a steam roller:
Start of crash: 315
Bottom of crash (potentially): 165
Conventional max for wave 1/A of the bounce: 225 (0.382 retracement)
Minimum retracement for wave 2/B: 195 (50%)
Which means if you want to be absolutely sure you will not lose your shares, dont go lower than 195 for now, 1 week at a time.
Before seeing your post, I Sold 25/11 180CCs yesterday at close. I will be happy to roll them to 195 2 weeks out if the SP goes up, that would mean I am about to lose my shares from selling CCs going tits up instead of the SP going to 140 ans getting margin called.
