Does anyone know of any good free sites that provide historical price data? I am looking to try out a few things and need some good accurate information on various futures prices going back a couple of years. Can anyone help.
i assume by historical price you mean equities only right? then even yahoo has csv/Excel free for download.
Thomson QAI and S&P PIT ...etc are top dogs in this area providing far more than just historical stocks prices (for example historical GICS classification, bps/eps...etc) which is used by less than most gifted portfolio managers and quant analysts to build strategies that consistently fail to beat the market!
