alert()

This function is useful for generating scirpt alerts directly on the chart in real time, such as popups, sounds, or sending notifications (via webhook, app) when a condition is met and an alert is triggered once per bar.

                alert(series string message) → void
              

          indicator("RSI Alert", overlay=false)

rsi = talib.rsi(close, 14)

if talib.crossover(rsi, 70) {
    alert("RSI crossed above 70!")
}
