Thanks, this is useful. I wish there was a possibility to upload some data, I'd be interested in intraday data (possibly use some free upload service). I have EOD delisted stock data for the big cap NASDAQ listed ones, I'm sure someone would find that useful.
Thank you for sharing! Does anyone know where to find free implied volatility data/graphs on the Futures markets? Thanks in advance.
One nitpick: the stock market was open on Saturdays up to the fifties. The dataset at MeasuringWorth.com besides going further back on the daily Dow, also includes Saturdays. I looked, none of those others do (nor does Yahoo Finance's data).
