Apologies for not pinpointing the exchange accurately, but many brokers aren't overly concerned about the specific stock exchange. Their primary focus is on my financial well-being, or at least that's the case with some brokers. This morning, TD wouldn't permit me to purchase ROI, so I had to resort to my reliable CenterPoint Securities. Not sure if it was on AMEX, NYSE or NASDAQ 100% profit is 100% profit....Have a nice day..Wish you the best also. The peanut gallery may be calling me BCNN.
