My question is, how does one go about objectively putting a price tag on an ATS? Yes, I'm aware of the old adages that sellers should charge as much as they can get and buyers should pay as little as they can. Screw that. I'm looking for objective criteria to start with as a pricing basis. You don't walk into a new car dealership with $100 and expect to drive off with a new car. There is a reasonable range of prices. But trading systems unfortunately seem to have no reasonable pricing method that I can find. The prices really are all over the place. Is there an objective method for evaluating the true worth of an ATS? If so, where do we find it? If not, can we develop one in this thread? I hope this thread will generate some positive feedback that is valuable to us all. Thank you.
