If he keeps his direct subscripition with Sierra, then it seems he cannot get it any cheaper. But if he opens an account with AMP, he will only pay half of what he pays now, without any disadvantages. Ok, he will need to deposit a few hundred dollars on an account with them, but that should not be a problem. To be fair he should place a few real trades at least once in a while, to support AMP for what they offer for such nice conditions. Does not have to be a FDAX trade (pretty risky), place a bid in some 2yr or 5yr bond futures (superslow), as soon as you get filled just go scratching. Nothing lost, but gave some support for AMP.
