Programming Alert for Indicators

Despite the fact that some indicators have already been reprogrammed to have alerts, I am yet to see any Awesome Oscillator indicator with alert.

Can somebody programme this or send the source code please?

I also built a custom indicator which I would want to add alert to. I am not much of a programmer but I try in my own little way.

If anyone is willing to assist please let me know so I can attach the indicator here or send it through PM which ever way is preferred.

If you think you cannot do it for free I might as well pay you in that case but you would have to consider that you are dealing with a student and as such reasonable charges must apply.

Here's a simple alert function I use.


DelayBetweenAlarm and SoundFile are external variables. If you want to have a sound play rather than an pop up jut comment out Alert() function and remove comments before PlaySound function.

Obviously to call the function is as simple as Alerts(1) or Alerts(2)

Enjoy

Hello Lux,

I am still findinf it hard fixing the codes. Here is the source code. Can you fix the alert to signal only if the current AO value is greater than 0 and the previous is below then vice versa?

Thank you.
