Share prices on different exchanges

Running Bing

I was looking for a graph of Bank of Irelands share price movements. I was looking at this page here on Yahoo finance: http://uk.finsearch.yahoo.com/uk/?s=uk_sort&tp=S&nm=BANK+OF+IRELAND

How come its a different price on each exchange.....what exchange do you choose to graph the price? Are the differences in prices just down to the difference in the times of the trade and should I just use the exchange with the highest trading volume to graph the price? Is there anywhere I could get an aggregate of BOI's movements across all exchanges?


And btw, no Im not looking to put any money into BOI;)

I'd imagine the prices are different because all the quote times are different, i.e. the share price is moving throughout the day.

Personally i'd go by whatever price is on the Irish Exchange because it's an Irish company, also going by the exchange with the highest volume would be the best bet for an accurate price.

Also if u check the Dax exchange, Bank of Ireland isn't quoted on it.
