MyBOLsAlert - MetaTrader 5 Script | Trading Script Download - MT4/MT5 Resources

The original code you can find here comes from bb.mq5 ( Bollinger Bands® indicator) from MetaQuotes Software Corp. Added some simple code to generate sound and email alerts. This latest version also introduces an arrow display as a shared idea inspired by Luis Gomez's comments.

The attachment you see now is the updated version 3.2 of this indicator (bugs and issues of the previous version have been fixed in this version).

Whenever the current price crosses the outer upper or lower Bollinger Bands, it plays a WAV sound that can be used as an audio alert indicator. The WAV will continue to play as long as the current price is outside the range. If you would like to receive alerts via email, you can select the add-on option that will send a message notification when the price exceeds the range.

It is also possible to set arrows in the indicator to display when the price touches or exceeds the upper/lower limits.

The sound time delay of the first version has been removed and replaced by a better routine that can handle the full playback time of any 3 second WAV file without slowing down or hindering the graphical drawing of the indicator on the chart.

For email notifications, by setting the correct SMTP email in MetaTrader 5 settings and using this indicator, you will be able to receive email message alerts. A command that sends a one-time email alert is triggered every time the price exceeds the upper or lower limit. It will not send another trade until the price hits the middle range of the indicator. The middle band will reset the flag or flag for the "ready to send" command, allowing the indicator to send a message alert.

These are just simple codes that are added to the job metrics to achieve the goal. I am not a professional programmer but a hobbyist and this is one of my MQL5 beginner programming. Someone asked for the same thing, so I thought I'd share this for those who might be interested for learning purposes.
