Data Sources (Free / Cheap)


“Data are the most valuable commodity to any investor. Before anyone can make a statement like "The market went past its 200-day moving average, and this is a bullish sign," one must examine the data and test the statement to see if the results”

Have at it:

Daily market data

Yahoo! Finance

Daily open, high, low, close and volume data on any stock in the U.S. Markets

For “slightly cleaner data at a slight expense,” James recommends Qcharts — which also includes the Tick indicator, and the Arms Index, as well as an indicator that tracks the premium between futures and cash (symbol: $prem).
