I understand Forex quite well. It's like every other straight instrument out there. (Options are the exception, because it's not straight, and I respect the hell out of the people who understand them. They're all bat-shit crazy. Love 'em.)
On a FX chart, if it moves up and you're long, you make money. If you're short, you lose money.
So your "friends, family and people" must not be very good at numbers?
And you are not, either, if you do not take me up on my offer. It is a win-win for you, since you will make a guaranteed $1,500, while I would receive only -$500 on the first go.
Do you grasp those percentages?
