referencing a third party indicator in my code

Hi,

I am quite new in using MT4 and started learning MQL4 and it is relatively easy as I come from programming background.

I have an indicator which is developed by a third party company therefore naturally no access to the source code.

my aim is to create some level of automation when the 3rd party indicator is triggered. is there a way I can reference the 3rd party indicator  in my code and specify criteria.

if possible would appreciate a sample code 

Regards
