Richard, I would expect that most Qchart users would consider themselves traders rather than investors. The EOD emini and S&P 500 futures data provided by Q is not the current industry format because it combines the regular session with the night session. The reason why this is not the common format is several fold but a couple obvious points come to mind. How are gap trading systems possible if all gaps are eliminated by the method of data presentation? With the intraday data the user has the option of selecting regular session or all sessions. I performed tests on both sessions in many time frames. Regular session data were compared on: 1, 5, 10, 15, 30, 45, and 60-minute time frames. All session data were compared on: 1, 5, 15, 30, and 60-minute time frames. The previously described data problems were fairly consistent in all time frames. I performed several hundred tests, which is several times the level necessary for statistical accuracy. Just to make sure that it was not a problem with the TA software program that I was using, I even tested with a second software program with the same results. It is the data, and there are not a million variables, there are only 4: open, high, low, and close. I did not use volume or open interest in any comparison because they do not commonly match from one vendor to another. If you are doing a trade based on last minutes or hours of trading do you believe the errors are so great as to effect trades? Yes, the data problems occur in real time and do effect the actual trade signals. I have had inaccurate signals caused by false information from Q. Buy signals triggered when in fact there was no buy signal with the correct data, and sell signals when there had not been a true sell signal with the correct data. Regards peter
