SC MTF Bollinger Bands for MT5 with alert

What is Bollinger Bands?

Bollinger Bands is a volatility indicator developed by John Bollinger. It consists of three lines: a middle Simple Moving Average (SMA) and two outer bands placed at a configurable number of standard deviations above and below the middle line. As market volatility increases, the bands widen; as volatility decreases, they contract.

Traders use Bollinger Bands to identify overbought and oversold conditions, detect breakouts, and measure trend strength. Price touching or exiting the upper band may indicate overbought conditions, while touching or exiting the lower band may indicate oversold conditions. A squeeze (narrow bands) often precedes a significant price move.
