Alerts from Indicators or Expert Advisors

 
Can anyone tell me if the alerts generated by indicators or expert  advisors that appear in a pop up box saved somewhere so that I can go and look at what alerts were generated  historically?
 

No. You can't read them, and you can't read the file because of the caching.

Figure out what buffer(s) values trigger the alert and use that.
