I think the ‘Texas’ part in the TXSE is mainly from a business procurement pov. They’re hoping to capitalize on the recent growth in the area, which is possibly ripe for a lot of new listings. The actual electronic trading might still originate in NJ.

I don’t believe they’ll have a floor. I think they are going the NASDAQ route, unless I’m confusing them with Long Term Stock Exchange (I was researching both around the same time).

Take the above with a heap of salt. It’s part my intuition and part things I might have read on the internet (including their corporate site).
