I want to know is there any connection between Nse/Bse and other Stock exchanges like Delhi/jaipur/vadodara stock exchanges. If Yes,then how do they work together???
In one word, your answer is NO.
Delhi doesnt have a stock exchange of its own.It had one, but its not operational.
Next, NSE & BSE are two different entities. They are like two different companies operating independantly of each other. Moreover, NSE & BSE are electronic exhnages and thus work very efficiently.
i dont know much about regional exchanges like jaipur etc,but they surely are not liquid.
