See -

Bollinger Band is not the property of a stock, commodity or some other instrument. It is property of the price. The Bollinger Bands we use, uses last 20 candles in the time frame in which we are dealing with.

Theory of probability distribution says there is 99.7% chance of reversal where there is a breach of Bollinger Band of 3 Standard deviation.

We can use that as a metric of our scanner.
