Hm...I have no idea of the delta of these strikes, but they look like being between 15 and 25...kinda.
And I can tell you that it is a very, very, very (did I mention very?) bad idea to sell these without protection ESPECIALLY on long terms.
Here's why:
https://myoptioncourse.com/option-vomma
Wingy (from 15 - 25deltas) options have the highest vega convexity, meaning whereas ATM options vega is linear. Imagine a stock with 5 vols. If you double the vol to 10, your ATM option will double in price.
Now think about the same stock, but this time take an option with like 0.01 deltas, a so called teeny. A teeny has almost zero vega, because it has zero optionality due to the fact that it is not within the return distribution.
But as soon as implied volatility increases, they become part of it. Their deltas increase and their vegas increase.
Imagine a stock with infinite volatility...that would make all options ATM, right? Now think about the transition of a teeny to an ATM option: It's delta, gamma will increase, but most important they will get some vega. And this process is not linear, it's convex.
Let's say a long OTM option has 3 vega, meaning for every vol point you gain 3$...but because an increase of implied volatility also increases the options vega...to now 5. So from now on you gain 5$ for every vol point increase. But if vol drops, you lose 3$ and the option has now only 2 vega and from now on you only lose 2$ for every drop in vol.
Vomma is also called Volga and more or less the abbreviation for VolGamma. I'm pretty sure everyone knows what gamma does to delta...well vomma does the same thing for vega.
Back to why it's batshit crazy to ever sell wings (<25delta) outright:
You gain: a little theta (non existent in these terms) and you are short vol, so you make a bit during a vol crush
Risk: gamma and short vomma
So basically you make less and less the lower vol goes, but you are getting your face crushed HARD once the underlying moves just a tiny but more: Your accumulate more and more deltas against you due to gamma AND you accumulate the more vega the higher implied vols go. You're basically short convexity in a big ass way.
I want to buy cheap wings when ever I can. Lots of them. Because wings are have so much vol convexity and ATM vega is linear, I can short ATM options all day without ever being at risk of blowing up. When you want to bet against convexity, it's your choice, buddy. I'm sure you'll be getting very good fills from MMs if you really wanted to be stupid enough to slap that monster on (but you aren't because now you understand vega convexity

)
EDIT: In case you wonder why I talk about OTM shorts when you actually are shorting ITMS: An ITM call = OTM put, so it has the same properties.
