Sharing an expensive lesson, rolling is not always profitable.

I think I have to share this, I hope no one comes into my situation, it has wiped out my premium gains for this year but lucky it didn't touch my initial capital. I'm thankful. ​ So I learned that during high IV, your ITM spread rolls will go into debit and for SPX it's a losing case. As far back that you roll your expiry date; It will still go into a debit. If I had sized my positions properly, which means smaller, it will be manageable by defending with OTM spreads, and wait VIX to die out. Initially I thought I have enough margin to handle this and ride it out, but what caught me off guard was how expensive it was to roll. ​ Please ask away, record it down, I'd be happy to share.
