i believe its an institutional platform, so if you want it, you had better have an account with a clearing member - they tend to distribute them to customers.
sometimes the clearer will wrap the cost of the platform in clearing fees, some time pass it on at cost....
I rang them today and they said they don't sell systems to the public only financial institutions, Bit shortsighted i think, I'll give my hard earned cash to the oppo.
Waiting for Proquote to call me back, i'll post more info when i get it.
Sorry but you are labelled a "legendary member", I would assume that with that title you might have worked in a broker at some point in your life. I am amazed by this thread that somebody had to point out to you that blokes in the street are not authorised to input orders into the LSE order book. Did you honestly think Fidessa is a broker or something?
