Price differences of calls relative to puts.

[Amateur]

I'm trying to create a script that could notify me whenever the difference in price between an ATM call and an ATM put was above a certain percent of the price of the underlying. I would also need it to be able to calcualte the percentage based on the time to expiration and convert it to a yearly percentage rate.
i.e.
Current price of XYZ = $200
Strike $200
Call $14
Put $10
Expiration 182 days

Spread of Call/Put is 2% of underlying with half a year until expiration which would be about 4.04% expressed as a yearly percentage.
Would be great if the script can also account for Strike prices that are slightly OTM or ITM.
I'm completely new to thinkscript and don't yet know what it is capable of. As such I was wondering if this is at all possible to do with thinkscript.

1. Is this soemthing achievable with ThinkScript?
2. If indeed it is possible, any resources that would help with writing such a script.

Thank you.

Post the exact formula you would like to use for expression as a yearly percentage.

Would the slightly OTM and ITM be increasing the spread between the strikes?
Or, do you want to go up a strike in calls, and then match that exact strike put as well?

How would you like to be notified? Is this for a chart, column, ..., ?

Exact formula would be something like {1+(Extrinsic[call]-Extrinsic[put])/strike}^(365/DTE)
Would be no big deal on Excel.
Would love to be able to have a scanner find calls or puts that are priced above/below a given range.
