Definition of *


I am not a math wizard.

What is the definition of the symbol * (star?)

I have seen it in several formulae.

Thanks.
It's the ass-to-risk ratio ... how much money you're willing to risk on any particular trade. Actually, it stands for "multiply" ... ex. 1 ES contract * 1,000 points = $50,000 (which is a nice trade depending whether it went for or against you).
