Bollinger Band Alerts for Price Breaks and Email Notifications
Summary
The document describes an update to a MetaTrader 5 Bollinger Bands indicator that alerts users when price moves beyond either outer band. It can play a WAV sound while price remains outside the bands, optionally send an email alert, and display arrows when price touches or crosses a band. An alert flag limits email notifications to one per excursion: reaching the middle band resets the flag so a later band crossing can trigger another message.
The post explains configuration needs, including SMTP setup and placing sound files in MetaTrader’s sound folder. It also notes that users can substitute sound files and adjust the indicator’s deviation when arrows are enabled. The evidence is a feature description, not a trading evaluation: no performance results, signal quality analysis, or guidance on whether band crossings predict reversals or continuation is provided. The author presents the changes as a hobby programming contribution for learning, so users should treat it as an alerting utility rather than a validated strategy.
Key ideas
- The indicator can play a sound when price moves beyond an upper or lower Bollinger Band.
- Email alerts are sent once per band excursion and re-enabled after price reaches the middle band.
- Optional arrows mark touches or crossings of the outer bands.
- Sound and email features require local MetaTrader configuration.
- The document provides no evidence that band crossings produce profitable trades.
