OK, so what you are talking about is a delayed quote like SI has.
I certainly wouldn't pay for it and I don't see anybody else being willing to pay for a delayed quote on each page. Simply because it is useless.
Offer a real-time or streaming service and I'd most certainly pay for it. That I can use. Delayed is like giving me last year's closing prices.
RTQuotes are so easy to come by these days. If you trade (generally a pre-requisite to finding this place), then you probably get as good/better quotes than what we could offer here.
I guess it is just a convience thing. But if we had X number of folks say they'd paid for X streaming/RT service then you are talking about something real.
But the reality of anybody paying for a delayed quote because it is below a message is kind of out of reality. Or is that the way you want it to come across clearly to everybody. <g>
The answer?
Find out exactly what people want and figure out if/how we can offer it.
So let's start. Excel, Muel, what do you want and what a fair cost?
