Are you talking about as an affiliate or actually doing trading?
I promote binary options as one of my many niches. The conversions aren't that great because most surfers need a lot of educating about what binary options actually are, and most of the tours out there are geared to people who are already traders. Like forex there is some heavy competition in the serps. However those $200 CPAs kick ass, a few of those a week definitely adds to the bottom line.
