Hi chunwaihome The way I'd do this is I'd first make an indicator as below. {Median Price} MP(); With this indicator plotted on a chart I'd first change the indicator to my preferred style and colour, and then I'd change the main price plot to the colour of the chart background. My next step would possibly be to save this chart as the Default Template or, alternatively, save as a differently-named Template. If the default template was changed I'd need to delete all charts created by the original template (but obviously would not delete raw market data). This procedure should work for all MS versions up to 11 but I cannot be sure that it will work for versions 12, 13 and 14. Roy
