By the way they are both getting data from the same source so I dont think that's it.

It's hard to tell specifically what's causing the difference in this case, as I don't know the logic & details behind the other program/chart, but there can be a few reasons. Since both charts are being fed by the same data feed, that rules out the fact that some data feeds package multiple trades together into one tick, while others don't.

With tick-based (tikcbars), volume-based (volume bars), or price range-based (range bars) periodicities, the formation of the bars is highly on the date/time where the bars begin. Investor/RT has an option for "Continuous Tick & Volume Bars" in setup: prefs: charts: general window. When checked, tickbars can cross session boundaries. When unchecked, tickbars will begin fresh at the beginning of each session. If using the former, the view period of the chart determines where the bars begin. If using the later, the bars always begin at the start of session. And in turn, you can setup your charts on the day session (sess 2) or the globex sess (sess 2).

Regardless, the underlying data is the same, but when you change the starting point of when you begin packaging that data into groups of ticks....then the bars will form differently. Hope that makes sense.

Slowly picking up the full functionality of IRT. I also use CQG but IRT has most of the features available at tremendously lower costs.

Heres a snapshot of my charts to show what IRT can do for you. Pretty neat. The horizontal lines are automatic mp levels.

Hi Chad,

If I already have a datafeed that isn't compatible with investor/rt, but I can export the database into a text file, is it possible to use this data? I think the backfill service is great, but it just seems a bit needless if I already have the data...

[LS_Chad]

Yes. As long as you can export the data to a text file or csv file, you can import it into Investor/RT. That includes tick data, daily data, monthly data, etc. You can even schedule periodic imports of data from specific files if needed.

To import data, choose "file: import: data". Once import window appears, hit the F1 key for help on importing.
