What changes did you have to make to the futures? It was not related to our latest addition through which we started offering the daily bars for the sake of yearly charts, was it? Thanks very much.
The problem was QT specific, not IB. It had to do with how much data was being returned, and futures tend to have more data for 5 day backfill than stocks. As for offering daily bars, I tried requesting more than 5 days of data with 1 day frequency using the beta TWS and still got an error that historical requests do not allow more than 5 days. What gives?
Which quote source do you recommend for Medved QuoteTracker, that displays pre-market NYSE & NASDAQ trading? Doesn't matter if its delayed. Thanks
Usually delayed sources do not bother with pre/after market data. We recommend Marketfeed and IQFeed for that. Your broker may also work well, depending on who you trade through.
Your original question was who has free data. Scottrade has free real time data for stocks and options that works with Quotetracker.
scottrade data is full of errors and ommissions...........i would mot advise anyone using real $$$ to trade to utilize this data source.
