Agree. But what is the point are we not entitled to get the data using an API from an exchange that is publicly traded. Is trading a private affair ?

  Well why should you be entitled to free data from a private corporation? Just because the exchange is open to the public to purchase on it doesn't mean their data has to be free. (just my 2 cents)

    my perspective was if public traded I need to be exposed information as I see fit. In one form or another should they not disclose their details for a buyer or customer who is going to invest (potentially )

      Because the exchange is not legally obligated to provide the information, and therefore can charge a premium for it.

      Just because something is public doesn't mean you get their services for free.

      a strong point. kind of puts a dent in the efficient market hypothesis, and the glorious dream that traders believe in: that the market is somehow inherently democratic. how are we expected to believe in this if we don't have access to the information? this asymmetry would seem to skewer emh. -- but then again ... checking the prices at "nasdaqtrader" the idea that we don't have access seems like the myth. $14 a month for Nasdaq issues ( I guess that means quite a lot of stocks ), is only slightly more than my Spotify. And if you don't have the money to pay $14 you probably don't have the money to make much of a dent in the market anyway! so what's the reality here? is data you can actually trade on that affordable or is it not?

        case I would then make is spotify is selling private art ( music ) from a private seller to public for a fee. it is like you pay for watching a movie from a private distributor. Trade is like I invest money for their business. I need to be informed buyer is what I would say. But then it is not about affordability or about I would be able to make a dent in the market. i will be fine if i can make a dent in my pocket. it is about information and data which like you say investors believe is democratic in nature ( but which it sounds like is not )

    Apple is publicly traded but surely you don't expect to get a real-time feed of all their transactions and revenue operations
