Bollinger Bandwidth - Bulge and squeeze

This is Bollinger bandwidth indicator:

Bandwidth = high-low/main

I have added lowest and highest of N periods to programmatically identify bulge and squeeze. When bandwidth at N periods low, it is in squeeze. If bandwidth at N periods high, it is in bulge.
