If you had a delta filter I would never use the ITM/OTM setting. It is useful to have the % ITM/OTM in the output, but not as a filter, for my use case.

In case it helps, my normal filter is something like:

- Type: PUT

- Days to expiration: 20 - 40

- Delta: -.30 - -.20

- Open interest: >100

- Premium: >$1

- Underlying price: >$50

- IV: 10% - 30%

That gives me a range of out-of-the-moneyness I'm looking for, but I don't care what the absolute % is.
