What fun would the markets be without ensuring there's always an information asymmetry at play?

Besides, nothing excites me more than looking through a bunch of third-party data provider websites that look like they were made in 2002, half of which don't even list their prices—but instead rely on sales teams to bilk the customer out of whatever they can pay.

Of course, that isn't to say you can't get your data directly from the exchange:

The only caveat is that you might need someone versed in Microsoft or Oracle enterprise licensing hell to actually decipher what's going on there.

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 ?

Grief, you any idea how much time I've spent _at banks_ trying to knock information into shape? There are _no_ good sources of this information. You take a feed from NYSE and I guarantee you'll find errors _on NYSE information_. The more complex the product, the more data points, the worse it gets.

And I've only talked about static data. If you want to actually trade, it gets much, much, harder.

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 )

true unless NYSE or other exchanges expose data in this modern world in all possible means for potential buyer. Is this not a fair ask ?
