I don't thing margin is available from my broker, but I wouldn't use it, as in principle I stay away from CFD providers because I want my stock in my own HIN.
Stock in a CFD pool can be used against you with sophisticated bot trading run by the CFD provider.
Then there is the risk of the provider not managing risk properly and taking all their clients down with them.
A poison chalice in more ways that just the leverage, IMO.
