Programmer needed to alter an indicator.

Hi,

I need the inclusion of a sound alert and pop up screen (if possible) in the attached indicator (Didi_Index) for MT4.

The alarm will need to sound every time the moving averages of 3 and 20 periods crosses the 0 line on the same location (please refer to the attached picture).

I also would like to have two different alarms, one to sound when the 3 periods moving average crosses the 0 up, and the 20 periods moving average crosses the 0 down (buy signal); and the second to sound when the 20 periods moving average crosses the 0 up, and the 3 periods moving average crosses the 0 down (sell signal). It would be nice to have the option to change the sound of the signals.

If possible, I would like that every time the alarm rings it opens a text box with the following information:

(1) The stock, currency, etc. where the alarm sounded;

(2) The time frame (15, 30, 1h, Day, etc.); and

(3) If it was a buy or sell signal.

Finally, this indicator has a minor glitch that I would like you to fix. Every time I change the timeframe of the chart the indicator lines disappear, and I have to load the template again for the lines to reappear. I don’t know if this information will help you, but the MT5 version of this indicator does not have this glitch.

Please let me know if you need any further information.

Thanking you in advance,

Rodrigo
