This chart is from Optionetics Platinum.
If you can read it, you might be able to profit from it.

 

Check ivolatility.com

 

that chart is ridiculous haha. i want to ivolatility.com, but charts the stock's IV but not the specific option's. How do i know if the IV on a specific option is high or low if i cant compare it to past levels?

 

Not everybody knows how to read it, let alone profit from it.
