God Indicator to Predict Start and End of Band Walk Review

This indicator calculates the width of the Bollinger Bands (the deviation between the upper and lower bands) and signals when a Bollinger Band shape (expansion, contraction) occurs.

・Logic of the Start Signal
Signals appear when the Bollinger Band width narrows and reacts to a squeeze.

・Logic of the End Signal
After a persistent “band walk” state occurs, the signal is triggered again when the band narrows once more. (Note: this is not merely a contraction; it involves expansion → contraction.)

Because signals are based on the shape of the Bollinger Bands, if no squeeze occurs and a band walk happens directly due to contraction, there may be an end signal without a start signal.
