Bollinger Bands Strategy and Formula in Trading


Bollinger Bands, a creation of John Bollinger in the 1980s, is an adaptable technical analysis tool applicable to various financial instruments such as indices, currencies, and stocks. As indicators of overbought or oversold conditions and a measure of volatility, Bollinger Bands play a crucial role in market analysis.

What are Bollinger Bands?


Bollinger Bands consist of three lines on a trading chart. The middle line is the 20-day Simple Moving Average (SMA), surrounded by an upper band (SMA + 2 standard deviations) and a lower band (SMA – 2 standard deviations). These bands act as an envelope around the instrument’s price, with widths determined by the standard deviation, representing price volatility.

Bollinger Band Calculation Formula:

The calculation involves a 20-day SMA and 2 standard deviations. The upper band is calculated as (20-day SMA + 2 * 20-day standard deviation), and the lower band as (20-day SMA – 2 * 20-day standard deviation).

How to Use Bollinger Bands:

Traders use Bollinger Bands on different timeframes to spot overbought or oversold conditions. When the price gets close to the upper band, it indicates overbought, suggesting a chance to sell. On the flip side, if it heads to the lower band, it hints at oversold conditions, suggesting a potential buying opportunity.

Complementary Tools: Moving Averages, Stochastic Indicator, ATR, and Keltner Channels:

While Bollinger Bands are powerful, combining them with other indicators enhances precision. Moving averages, Stochastic indicators, Average True Range (ATR), and Keltner Channels are valuable additions. Our new platform easily combines tools, helping traders make smart decisions.

Bollinger Bands Strategy:


Traders use Bollinger Bands in different ways. One strategy is “riding the bands,” but be cautious and don’t mistake band penetrations for signals. Another strategy, the “Bollinger Band squeeze,” predicts higher volatility when the bandwidth hits a six-month low. When using these strategies, it’s important to know when to buy and sell. Consider buying when prices touch the lower band, indicating a potential buying opportunity. On the other hand, think about selling when prices touch the upper band, suggesting a possible reversal. Understanding these strategies and their signals helps traders navigate the markets more accurately.

Best Bollinger Bands Settings:


Tailoring Bollinger Bands to different timeframes and trading strategies is essential. Long-term traders may prefer monthly charts, while day traders opt for shorter timeframes. There’s no universal timeframe; it depends on the trader’s strategy.

Bollinger Band Patterns:


Traders gain insights by spotting patterns like double bottoms and reversals. Double bottoms show a switch from sellers to buyers, often leading to upward movements. Reversal patterns, breaking upper or lower bands, may indicate trend changes.
