title: [pine-script], how can i create ALERT, of multiple "alertcondition" , on MULTIPLE security ()
body: <p>in pine-script (trading view).
  how can i create an Alert. where Multiple &quot;alertcondition&quot; are activated on <strong>multiple</strong> securities.
  for example:</p>
  <p>// Code for alert with price above 250
  priceAlert = (close &gt; 250)</p>
  <p>alertcondition(condition=priceAlert,
  message=&quot;Price is above $250&quot;)</p>
  <p>AND</p>
  <p>// Code an alert with price below 75
  priceAlert = (close &lt; 75)</p>
  <p>alertcondition(condition=priceAlert,
  message=&quot;Price is below $75&quot;)</p>
  <hr />
  <p>will be applied to <strong>multiple</strong> security():</p>
  <p>SMN() <strong>AND</strong> VXX() <strong>AND</strong> spxs() etc.</p>
  <hr />
  <p>***alerting, only when all alertconditions, applied on <em>all</em> securities().</p>
  <p>Thanks</p>
