The "ExScript" indicator passes data to an external program and then plots the output that is returned.
See the example CUS indicator at
Copy the companion Perl program ExScript.pl to somewhere in your home directory. Now edit the indicator example to refer to that pathname.
# That example indicator outputs just the "date,volume" for each bar, as well # as the commandline argument scaleFactor, and calls this Perl script. # The script calculates the average of all bars, gets the difference # from average and scales it. The script then passes the data back to the # indicator which plots it as a "Histogram Bar". It is a silly example which # could be done directly as a CUS script, but it gives an idea of the power. # # For example, it could also be enhanced to access the xml summary which # is exported using the "Tools => IndicatorSummary".
