NxCore starts at $500 per month. The benefit is it is a full broadcast feed (you don't set a watch list of symbols) of every trade and every quote for the exchanges you subscribe to. The key advantage of this feed is the compression/efficiency of the delivery. For example, the entire US equities feed can be sent on a standard broadband connection with high reliability and low latency. It is build for the institutional market, and thus there are no retail 3rd party applications that currently support it (most retail users aren't willing to pay for it). Jay
$500/mo sounds quite reasonable for a professional quality feed and would certainly be within reach of semi-pro traders. Although the majority will not pay this much there is a small percentage of serious independent traders that realise the benefits of having good data who will. Unfortunately, you do not have the market coverage I require. Would like to see a middle tier revendor taking a Comstock or Reuters wholesale feed and providing something aimed at pro/semi-pro users. Needs to allow broad market coverage and support 1000s of symbols to allow research databases to be populated.
