cfd traders your assistance please

How much down would you need to short a company like the Ox getting exposure, for arguments sake of say $100,000 worth of stock currently ?

Do people trade CFD's constantly on HC?

I can see how magnificent they are for leverage as warrants are but acknowledge they both can be very dangerous as we have witnessed today if in metals and oil. But if you get a major turning point right you can even outdo the big boys using a lot less dollars.

Any successful CFD traders here?
