Edit: For example if I wanted to invest in a business through LTSE today, is cboe how I would do so? What would my order flow look like?
to find out if your preferred broker or market maker is a member of LTSE, you can ask FINRA: https://brokercheck.finra.org/
Edit: Also, he didn't quite answer my question. I asked how one would find out what companies are listed, not for a list of what's currently up.
I might assume that they'll eventually be on their website but I've now asked twice and gotten answers about "preferred brokers" and "market makers" (I honestly don't know what that is) and another saying that this stock exchange has no stock to exchange. Again, I am not savvy in this area but it seems reasonable that "how would I view what's available?" wouldn't be to difficult of a question. If the answer is "those listings aren't 'For you' as a non-professional investor" then I'd be happy being informed.
It's correct that you can't just walk up to NASDAQ and make a trade, but I can find some information about what companies are listed there easily on their website. As far as I can tell, "open for business" kind of looks like "We've finished our copy about our ideals and goals and put it on a webpage" in this case.
I could be wrong or just totally missing the point but I still don't know what is listed or how to engage with it. Is it normal not to provide that information as a stock exchange?
