Pay per trade: only if 40 pip+ profit (forex)

Hi,



I have been thought about your payment system, which is offering some choice for system vendors as of now.



What I am missing is something like a "pay xy USD per trade, but only if this forex trade made 40+ pips".



This would really help subscribers in a way that they can calculate easily whether the subscription costs are ok for them.



If trading autotrading via IB, you would know then that a 40 pip trade means usually about 100 USD (if trading minimum available size).

So a fee of (say) 10 USD per 40 pip trade would be fair for both system vendor and subscriber IMO.



What are your opinions about that ?



Best regards



Jean Marc
