title: Adding variables to alerts in pinescript
body: <p>I would like to use the same alert condition in a pine script for several stocks in TradingView.  The problem is that I won't know which stock triggered the alert unless I create copies of the script and have a custom message for each script.  I would like to have something like:</p>
  
  <pre><code>alertcondition(someCondition, title='Bullish', message=tickerid)
  </code></pre>
  
  <p>where I use the tickerid variable which is one of pine scripts built in variables.  However, when I attempt this, the message I get is literally tickerid instead of the tickerid of the chart associated with the script.  Is there any way to dynamically generate the tickerid?</p>
