Alert conditions

The annotation function alertcondition allows you to create custom alert conditions in Pine indicators. One script may have one or more alertcondition calls. The function has the following signature:

alertcondition(condition, title, message)

condition

is a series of boolean (true or false) values that is used for alert. true means that the alert condition is met, alert should trigger. false means that the alert condition is not met, alert should not trigger. It is a required argument.

title

is an optional argument that sets the name of the alert condition.

message

is an optional argument that specifies text message to display when the alert fires.

To create an alert based on an alertcondition, one should apply a Pine indicator with an alertcontidion to the current chart, open the Create Alert dialog, select the applied Pine code as main condition for the alert and choose the specific alert condition (implemented in the code itself).

When alert fires, you’ll see the message:
