I dont understand why Im getting 2 different results when I thought I was saying the exact same thing.

market is nasdaq
If I use... add column historical volatility today more than 43 days ago .... then I get 208 results.

If I use .... add column historical volatility today more than historical volatility 43 days ago .... then I get 1725 results.

Why is that? thanks

add column is for single values. You can't use statements in them.

In the first statement you're not specifying what 43 days ago.

You're closer in your second statement. Use it and then add columns with each value:

Fetcher[
historical volatility > historical volatility 43 days ago
add column historical volatility
add column historical volatility 43 days ago
]
