I make little modification in my post.
I just want to add chart link on my alertcondition. It could be useful for those who trade with many pairs / instruments.

volEMA = ta.ema(volume, emaLength)
alertcondition(condition=volume > volEMA,
 message="Goto EURUSD")

Unfortunately I didn’t find anything related. I’ve tried with single & double cbrakets {{ }} but it doesn’t work.

Thank you in advance for the help
