Error Using Add()

[freewind]

Hi,

I'm trying to load automatically a list of instruments to my correlation indicator and I get the following error message for each unrecognized instrument:

The indicator 'zCorrelationScanner' has called the Add() method with an invalid instrument. Either 'EXTR' does not exist in the Instrument Manager or the specified exchange has not been configured.

When I load EXTR ticker to the chart it load with no problem and then when I want to load it again automatically to the indicator the error doesn't repeat itself.

Is there a way to configure many ticker at once, for example all NASDQ stocks?

Thank in advance,
P.s. attached the error log

freewind, have you added EXTR to the instrument manager?

There is an unsupported method for adding many instruments to the instrument manager at once. Please search the forum for "instruments.txt" to see how.
