Red and Green Lines

[[Deleted]]

I just downloaded the Matatrader 4 system. Since I am new I have not found a way to addthe  green indicator line to the chart. The red line is already present. Can anyone take me through the steps?

If you want an "indicator line to the chart" add an indicator to the chart.

[Tjipke de Vries]

double click on the line 

then parameters of that line has to appear

you can change  color red to green

If it is about the color of an indicator than you can right click on the chart, select indicator's list, edit the required indicator and select the color from colors tab.
