Why couldn't you just look at a daily chart, decide what time of the day you want for the open and close, and at the same time see the high and the low? Each candle on a daily chart represents one day, so is that what you're looking for?
here, try these guys: http://www.forexdata.biz/index.php?action=freethe quotes are free and are indicative, but that should be fine for end of day analysis. If I was looking at intraday action I'd look for real broker quotes vs indicative.
