Every time volatility is low we can make this type of trades expecting a high success rate.
The Vix (volatility index) is below 14 so I like to redeploy a SPX PUT calendar buying the DEC 2115 PUT and selling the NOV 2115 PUT.
This is a volatility and I like to always have this type of trades on. I got filled at 15.40 and my target is 10% of the cost or $154.
