Lets go over the steps to plot Chart and Grid once
again:
Once you copy the new code* at the end of the message
You need to perform the following:
Set Blank bars in right margin to 10 .
Preferences
Window
Right click on chart select Parameters and press "YES" on
"PlotGrid" option.
Parameters
Window
Note that:
Grid is plotted for the chart area in the right of Vertical
Selection Line. Chart
and Grid
* The following code includes the option to choose form 3 ways of calculating
the box size:
1. Traditional (Box size default
value = 1 with increments of 10 points)
2. Percentage (Box size default value 1%
of last value close with increments of 0.1%).
3. Average True Range (Box size default value last value ATR
(20) with increments of 10 % of ATR (20) ).
You can choose to apply this from "Scaling Method" drop down
menu in Parameters
Don't forget to
check the code in formula editor before you apply
