I am looking for a source for intraday historical candlestick data. For example, I am interested in downloading the first 1 hour candlestick data (open,high,low,close,) for each trading day for the last 6 months to year, for selected stocks. Can anyone recommend a good website, or software package that can accomodate this requirement? I would prefer a free data source; however, I am willing to pay a reasonable subscription if necessary. Thanks.
