Hi, I found a few links with free historical end-of-day price data for futures containing open, high, low, close, volume and open interest. PI Trading http://pitrading.com/free_market_data.htm Trading Blox (10 years of data) http://www.tradingblox.com/tradingblox/free-historical-data.htm Turtle Trader http://www.turtletrader.com/hpd.html I'm specifically looking for end-of-day data for corn, wheat and soybeans that goes back to 1985. My problem is that none of these sources can give me exactly what I need. PI Trading has continuous data, but it doesn't specify where the contract rollovers are occurring. Trading Blox only contains 10 years of data. Turtle Trader contains individual contract data, but every file has missing dates. OpenTick doesn't seem to be taking new members. IB only supplies 1 year of data. Does anyone know of any other good sources of end-of-day futures data at a reasonable price?
