alert

The alert namespace provides a callable function for triggering alerts during script execution. In PyneCore, alerts print a highlighted message to the terminal rather than sending notifications — the freq parameter is accepted for Pine Script compatibility but has no effect at runtime.

Quick Example 

from pynecore.lib import script, alert, ta, close

@script.indicator(title="Alert Demo", overlay=True)
def main():
    rsi = ta.rsi(close, 14)
    if rsi > 70:
        alert("RSI overbought!", freq=alert.freq_once_per_bar)

Functions

alert()

Prints an alert message to the terminal. Outputs with color and formatting if typer is installed; falls back to a plain print otherwise.

ParameterTypeDescription
messagestrThe alert message to display.
freqAlertEnumAlert frequency. Optional, defaults to alert.freq_once_per_bar. Currently ignored.

Returns: None

alert("Price crossed above SMA!", freq=alert.freq_once_per_bar)

Constants

ConstantDescription
alert.freq_allEvery call to alert() triggers the alert.
alert.freq_once_per_barOnly the first alert() call during a bar triggers the alert. (default)
alert.freq_once_per_bar_closeTriggers only when alert() is called on the bar’s closing execution.

Compatibility Notes

  • The freq parameter is accepted for Pine Script compatibility but is not enforced — all alert() calls produce output regardless of the frequency constant used.
  • There is no support for alert conditions or webhook-based alerts. alert() is terminal output only.
