When buying calls, how do I find the "DELTA" for the transaction?

Question

I have searched several search engines but I have received no answers. Why?

Answer 1

Depends where you look. Most good brokerages will have screens that allow you to look at the "greeks" which include delta for a call.

For example, in OXPS (OptionsXpress, there's several screens that go into the greeks including Delta, Gamma, Theta, and so on). If your broker doesn't have these things, you might consider getting a new broker. It should be standard.

There are also several toolboxes that have them as well, usually for a subscription price, but depends on what you're looking for.

If there's one in mind I could help you look up, just let me know.

Hope that helps!

You can calculate a rough approximation on your own. The reason you don't see many delta's is because 1st: its constantly changing. 2nd there many different ways to calculate it and may involve complex models. 3rd: Using delta for forecasting is usually disappointing because it changes continously as the underlying price of the stock increases, thus they are not super reliable and open for intrepretation. I would recommend calculating deltas yourself
