See "Setup: Preferences: Import/Export".
Here you can specify whether you wish to be prompted for a comment or
not. If you elect NOT be to prompted, you have the further option of
specifying "no comment" or a fixed comment of your choosing, e.g. "This
RTL object compliments of Charles Dow".
The comment exported with the RTL object is displayed to the recipient
when someone imports your scan, signal, or custom indicator.
If you wish to add comments to a specific RTL object, add text anywhere
you like inside the formula area of the RTL setup. e.g.
CL > MA; /* find instruments
trading above their 100 day moving average */
Any text in the syntax area that is preceded with /* and
terminated by */ is ignored by the parser.
/* this is a comment */ CL > MA;
/* and more comments */
does the same as:
CL > MA
