Old fart that I am I am constantly watching my retirement portfolio. I am wondering why the stock prices are always delayed 15 or 20 minutes. I know it is an exchange rule but don’t seem to be able to find the reason why.
I used to use this fancy widget called the INET bookviewer which gave real time bids and asks for a given security but that has been shut down and requires a subscription.
Is that it? It is so profit can be made by giving real time to only paying customers?
