Vertical Spreads Basics:
Vertical Spreads are Directional plays with predefined risk/reward, normally used as a stock replacement strategy.
Credit spreads have a greater probability of success but higher risk, while debit spreads have a higher reward/less risk.
Credit spreads are better when IV percentile is high while Debit spreads normally work best when the IVp is lower.

We’ve been placing SPX credit spreads selling Delta 10 and utilizing a spread width from 10 pts. to 25 pts. The reason for this has been that the probability of success is greater the farther out we go; well, that is correct, but only when we hold the position to the end, win or lose.
However, on a Delta 10, 25 pts. spread on the SPX we risk $2,250 to make $150. So to avoid such a big loss, we mostly bail when the loss exceeds 2.5 or 3X the max profit. Once we do that the probabilities of success are not what we expect, but a lot less. So we are shortchanging and lying to ourselves believing that we are trading a high probability, non-directional strategy.
On the last link above, the guys at TT show the right way to trade this strategy.
They go out to 40-45 DTE and use a spread width equal to 2.5% of the price of the underlying and Sell at Delta 30 and get a premium greater than 20% of max loss.
On the SPX the spread width of 2.5% is 50 pts spread. 2000 X 0.025 = 50.
So with the SPX trading at 2000 as per Friday’s Mar 4th 2016 close, to sell a BeCS we will go to Apr monthly and sell the 2045 at $15.30 and buy the 2095 for $2.80 for a credit of $12.50.
Max loss = 5000 – 1250 = 3,750.
Prob. of Success = 3,750 / 5000 = 75%.
I believe this makes more sense.
What do you guys think?
