Comparing Charts to Scanner
Comparing instrument values on charts and in scanner
When you have one and the same symbol used in the scanner and on a chart it is natural to start comparing the data values in both windows. This is when you can spot slight differences. As a rule they are caused by the difference in the symbol settings in these windows. Cross-check that the following settings are identical:
- Data source and symbol;
- Chart type - regular or non-standard;
- Resolution;
- Quote Field;
- Sessions;
- Build volume on;
- Data Range* - should be specified as Bars/Days Back on the chart because there’s no From-To data range in the scanner; make sure that the pin position is identical in both cases;
- Time Zone*.
The easiest way to guarantee that the settings are similar is to create a chart for a symbol used in the scanner! [[Working_with_Grid#Creating_Chart_Directly_from_a_Scanner_Window|See here}.
Comparing indicator values on charts and in scanner
If there’s a discrepancy in the chart and scanner indicator’s calculations, then it may be related to:
- different symbol settings (see point 1 of this article);
- different indicator settings. In this case compare and adjust:
- the input values;
- the Max Bars Back setting;
- the Update on every tick option state;
- the Skip identical ticks option state.
