Bollinger Bands Breakout Alert Indicator for MT4 and MT5

The Bollinger Bands indicator is very well known by traders. It is one of the standard indicators available in the MetaTrader 4 platform, however, there is an issue. MetaTrader 4/5 doesn't have any built-in function to alert traders about breakouts of Bollinger bands. This is why we created the Bollinger Bands Breakout Alert Indicator for MT4/MT5.

What is Bollinger Bands Breakout Alert indicator for MetaTrader?

Many traders rely on the Bollinger Bands as a tool to confirm entry and exit signals. Also, quite a few strategies are based on Bollinger Bands breakouts, bounces and so on.

The problem with MetaTrader is that it doesn't have a system to alert the trader when a breakout of the Bollinger Bands happens.

The Bollinger Bands Breakout Alert Indicator for MT4 (and MT5) was created exactly to fill this gap. This indicator is like a plain Bollinger Bands indicator but including a notification system. You can be alerted via alert on screen, email, and mobile app if there is a breakout of the Bollinger Bands.

The Bollinger Bands Alert Indicator can notify you in case of a price break out or when the price returns in the bands after a breakout.

Bollinger Bands Breakout Alert indicator parameters

The Bollinger Bands Breakout Alert Indicator for MT4/MT5 has very few parameters so that it can be useful as well as easy to use.

Most of the parameters that you set concern the basic settings for the Bollinger Bands and how you would like to be notified. Here is a detailed description for some of the parameters:

• Candle To Use For Analysis — which candle to analyze for a breakout. It can be either the Current candle (the right-most on the chart) or the Previous (the latest completed one).
• Ignore Same Candle Crosses — whether to ignore signals when it is just the same candle that opened on the one side of the BB and closed on the other side of it, even if the previous candle closed on the same side of the BB as the current one. Setting this parameter to true will basically require the previous candle to be closed on the opposite side of the signal candle's close.
• Number Of Candles To Analyze — to avoid unnecessary calculations, the indicator will check the Bollinger Bands breakouts only on the latest N candles. You can set this parameter to zero to make the indicator analyze the entire chart.
• Enable Notifications Feature — if true, the indicator will send notifications upon triggering.
• Send Alert Notification — if true, the indicator will issue native on-screen alerts.
• Send Notification Via Email — if true, the indicator will send emails when it detects a breakout. Email alerts should be set up properly in your MetaTrader platform's options for this to work.
• Send Notification To Mobile — if true, the indicator will send push-notifications to your mobile device. Mobile notifications should be set up properly in your MetaTrader platform's options for this to work.
• Output Signals to Buffer #3? — if true, the indicator will output its signal values (1 = Buy, -1 = Sell, 0 = Neutral) into indicator buffer #3. You can use this to read the indicator values via iCustom() in your expert advisors.
