@ niftymover: Thanks niftymover for the help. Actually i am aware of BFD people, but at an indian forum by the name trad..ji dot com the reviews are not good, they are having many problems regarding the data feed, one person there by the name of amarnath is trying to help them but he also cant do much.. demo a/c data feed is not consistent some times its there some times its not there... many problems.. i am ready to pay the money if service is good... anyways thank you once again niftymover.
