Some Questions for experts on historical price Data?

Discussion in 'Data Sets and Feeds' started by Nana Trader, Jun 22, 2005.

  1. I have two questions:

    1-Why Historical data providers charge higher price
    for 1 minute intraday compare to 5 minute intraday?

    we all know that 1minute bar can be converted to
    5 minute bar and higher , So what is wrong with
    breaking 5 min bar down to 1 minute bars? Will
    these cause any inaccuracy when testing?



    2-Which Data feed has longest historical data that
    can be downloaded into products like Qcollector
    from mechtrading.com (www.quotelink.net collects
    realtime data, not historical).
    Problem is Esignal provide 120 days intraday history
    http://www.esignal.com/esignal/features/featureslist/data.asp
    while what tradestation offers is beyond compare to
    Esignal. http://www.tradestation.com/strategy_testing/hist_market_data.shtm
    So is there a way that you can automate hundreds of
    symbols at a time with Historic intraday data to be
    loaded into excell program after market closed each
    night?



    3-HistoryCentre 3.0 for TradeStation/ProSuite 2000i http://www.pcharts.com/hist/hc/
    Does anyone using this product, how long will it take for
    each symbol historic intraday data get loaded directly into
    TS2000i (i mean without having to convert to XPO then
    import into global server)?
    And how does TS2000i can integrate with any ASCII data
    for direct import, because above site seems hasn't mentioned
    anything on this?

    Nana:

    I'll answer the easy one. You must have had a bad morning. Assume a stock trades as follows:

    All are Open, High, Low, Close. Stock trades are reported by minute, not by tick.

    1, 3, 5, 5
    5, 5 ,5, 5
    4, 4, 2, 2
    2, 2, 2, 2
    3, 3, 1, 3

    A 5 minute report would be:

    1, 5, 1, 3

    There is no way to reconstruct the one-minute data from the 5 minute date. Obviously the reason the data provides charge more is that you are get five times the data.
     
  3. Sure, i had a bad morning, :) i was thinking of 5minutes
    worth of tick data which could be break down to 1 minute
    interval.

    Thanks, Question one is answered, please proceed with
    next two questions
