Hello Dennis
Ok..say I'm going by the ticks, and that gives me a week worth of data. Now, if I switch over to the hourly chart, that would give me the equivalent of the week worth of data in terms of ticks. In other word, say a week of tick data is 500000. When I switch over to the hourly chart, that would give me 500000 hourly bar? And when I choose the daily chart, that would also give me 500000 daily bars, or however long the data in existence is. Do I understand that correctly? If that's the case, then I'm not getting that much data. When I initially set the database at 500000 on the tick or 1-minute basis, I'm getting a lot of data--which is fine w/ me. However, as soon as I'm switching over to a longer time frame, say hourly or daily, I'm not getting as much. In fact, on the daily chart, I'm getting somewhere between 10 days to 15 days max.
