Faster decay in longer DTE

status1

Well-known member
Is there a reason why a longer DTE would gain more p/l per day with lower Theta than a shorter DTE ?
I am doing simulation in SNOW with almost the same strikes one is expiring on Jul 28 and has 56 Theta and p/l of +$18
The other one is for 20 Oct expiration and has 18 Theta and p/l of +$79

This is just a strangle strategy
They were both placed on Jul 20
It seems like it would be better to place the farther out trade even though the Theta is lower
 
Most likely due to the volatility skew and the concavity of these term structures can be quite different
