Hello,
I've gone through the NT8 @VolumeUpDown.cs Indicator but can't see how to add an alert for specific condition.
The specific condition is very simple:
Fire an audio alert every time the current Volume Bar value on each tick is Greater or equal to the average volume of the past x number of bars.
The Number of bars to look back should be customisable as user input.
The logic should look something like that for the past 10 bars average (pseudo code as I'm new to C#):
How do you get that result?
Thanks for your help.
Here's the copied @VolumeUpDown.cs code for quick reference

Code:
IF
ON EACH TICK CALCULATION
CURRENTBAR[0] >= AVERAGE(Bar[-10] to Bar[-1])
THEN
FIRE SOUNDFILE.wav
Thanks for your help.
