dsacco, the reason why eBay of all places is simple, I like to buy cheap stuff on eBay, especially books, so I am always searching for books on the investing subject, so I can get ideas to back test and this is how I first stumble on the data and since the price was so cheap I got it and I tested it to make sure it was OK. If it was not, I would have notify the seller, eBay and PayPal and get my money back... Before this data, I was using Quntopian, but the huge limitation there is that you cannot test on the whole market, you cannot download their data, etc... Anyway, I am trying to give an honest advice here and to prevent people of losing money because they don't know what they are doing...
