Hi,
In my web site I am using "http://finance.yahoo.com/d/quotes.csv?{0}&f=sl1d1t1ba&e=.csv"; as a web service to connect and get the rate exchange. but it returns the real time rate.
I was wondering that is there any way that I can get the max rate of the day before instead of the current date.
Thanks in advance
