Description

Market scanner resets on every 80th bar of real-time data. It will also reset the indicator that is applied to it.
Tested on 2 different computers,
Tested on x32 and x64 bit computers,
Tested on 32-bit and 64-bit trials,
Tried from 2sec to 3min resolutions,
Tried to use single or multiple symbols in one scanner,
Tried to adjust MaxBarsBack and number of preloaded historical bars,
Tried to use Symbol_CurrentBar or CurrentBar or BarNumber.
Always the same outcome with the scanner.
The same indicator works well on charts.
Tested with IQFeed.

There is another important issue that might be related to the same bug:
When indicator gets reset by the scanner then PowerLanguage statement Once (and everything that's within it) gets skipped by MultiCharts.

Steps to reproduce this issue

If LastBarOnChart And BarStatus = 2 Then Print(Symbol_CurrentBar);
When it reaches 80th print it resets itself back to initial values, also resets the indicator that is applied to it.

When you have Bars Back set up in the Scanner, after new 80 bars received in real-time the starting point of the price data series is shifted to 80 bars (old 80 bars are put aside) and the indicator is re-calculated.
 
It's not a bug, this is the current implementation that has been developed in order to save memory.

The workaround is to use Days Back; in this case the indicator won't be re-calculated every 80 bars.

For some users it may be important to save on memory use, I agree. This is great that when set to Daysnot Barsback it stops resetting.
Could you make a warning message appear or pop up when Use Custom Data Range is set to default (this resets it too, btw) or Bars Backso users are aware of this.
Thank you.
