Create Alert from Indicator with No Plot

[nightlights]

Hi,

I have a custom indicator which draws an object (e.g. dot) when certain conditions are met. As such, this is not a Plot and I do not have an AddPlot(). I do have a Series<bool> variable to store "true" values when these conditions are met. I notice that under the Alerts Window, I am not able to create an Alert based on this indicator as it does not use AddPlot() to plot anything on the chart.

I understand that I can use Alert() to hardcode the alert in the script. But if I do this, does this mean that the alert will be permanently on?
I would like a way to manually turn on or turn off the alert, like how I can do so using a manually created alert. How can I do this?

Thanks.

Hi nightlights, thanks for posting.

You can either create a plot and set its brush to Brushes.Transaprent or implement a boolean public property to toggle the alert on or off e.g.

[NinjaScriptProperty]
[Display(Name="Toggle", Order=1, GroupName="Parameters")]
public bool Toggle //this will show up in the indicator settings.
{ get; set; }

Kind regards,
