This may not be the case depending on the technology. For example, when you place a trade there could be technology to notify their black box such that the black box then mirrors the trade i.e. No strategy needs to be revealed it's simply a matter of mimicking after the fact. I'm sure the OP does not expect you to take his assurances on good faith, hence to offer to arrange a call so that further due dilligence for both parties can be undertaken. ET is such a cynical place! Give the guy a chance to provide enough rope to hang himself...and then pounce. Until then, benefit of the doubt may be appropriate. Perhaps, the OP could provide some more details on the process. MoMoney.
