that's not a avatrade chart. I have been using them since they offered bitcoin trading, and I'm doing pretty well.
Is Ava's underlying instrument MtGox's / Bitstamp's / other's BTCUSD?
No it's a CFD. Bitcoin on paper.
http://en.wikipedia.org/wiki/Contract_for_differenceYes, I know it's Bitcoin on paper. I want to know whether it is based on:
a) a price from a certain exchange like MtGox (Plus500 does it) - one would be fine with it because one can easily verify the price
b) a price derived from an unknown algorithm (1broker does it) - one would expect to be fucked in the ass.
I don't know. Plus500 like to freeze trading when the price is moving and 1broker don't seem to be doing it.
