Triple Bollinger [SimpleTrade]

Triple Bollinger Bands plot three concentric sets of Bollinger Bands—typically using the same moving average but different standard-deviation multipliers (e.g. ±1σ, ±2σ, ±3σ). This gives you:

Inner Band (±1σ): captures ~68% of price action—good for identifying normal volatility and early trend moves.

Middle Band (±2σ): the classic Bollinger range (~95% of prices)—signals medium-strength breakouts or pullbacks.

Outer Band (±3σ): extreme volatility (~99.7% of prices)—marks overbought/oversold or major exhaustion points.

By watching how price interacts with each band, traders can gauge trend strength, spot gradual reversals at inner bands, and prepare for sharp moves (or reversals) when outer bands are touched.
