Why amibroker send signal to pi ( for selected chart only )?

Amibroker generate signal to only selected chart. Suppose I have open 5 chart in amibroker but amibroker send signal to active or selected chart only. So whats the problem ?

Ideally Amibroker sends out/generates signal for the all the active symbols which are requested by

a. Manually clicking on the symbols

b. Running a scan on all your selected symbols.

If some signals are not getting generated from your charts which you have not selected, it could be an issue related to your code.

Please share your code in which the signals are getting generated to help you better.
