Charts with certain periodicities require tick data in order to form properly. These include Volume Bars, Tick Bars, Renko, Point and Figure, Range Bars, and Change Bars. These periodicities can also be formed from 1-minute data but generally they will not be as accurate. For periods where there is tick data, Investor/RT will use the tick data to form the accurate bars. Using a proprietary algorithm that simulate a full tick by tick trade distribution from a 1 min bar data, it will then use the information derived from this 1-minute data set before that to form those bars as best possible. By default, Investor/RT will form bars from 1-minute data for up to 50 days back. For periods before that, Investor/RT will create a single bar per session. The 50 days setting can be increased by the user by setting a configuration variable. To adjust this value....
- Choose Setup > Preferences > Configuration from the main menu
- Choose the configuration variable SimulateTickDataDaysBack and set it to 100 or whatever value you wish, and press OK.
- Now close and reopen the chart.
