Bollinger Band MT4 Alert

Hello, 

I am wanting to create an alert for when the Bollinger Bands break a squeeze. My strategy uses the break of the top and bottom bands in the opposite direction as a momentum indicator, then I look for the first candle close above the midline. Is this even possible? I have my standard deviation set to 2 on my Bollinger Bands indicator. I am attaching a picture and have circled the area on the chart of what I am looking for as an example.
