E-Mini's Debit Put spread

I prefer to sell options rather than buying them, but the Implied volatility is still low and a correction from the last move up on the E-mini's will make the volatility expand, giving this trade a quicker path to profit. I will be buying a 2160 Put and finance part of it selling the 2120 Put. Risk to Reward is over 1:2 (Max loss of $600, and max win of $1,400 per contract) with a 45% Probability of finishing In the money.
