Bollinger Bands a powerful topic of our share market classes!

Bollinger Bands was introduced by John Bollinger as an effective technical analysis tool in the early 1980s. Consisting of three lines plotted onto price charts, Bollinger Bands allows technical analysts to gauge market activity with greater precision than ever. They feature three bands or lines (BOLLER BAND 1, 2, 3 on price charts). These bands represent:

1. Upper Bollinger Band

2. Middle Bollinger Band

3 Lower Bollinger Bands


The Components of Bollinger Bands

A. Simple Moving Average (SMA)

The Middle Bollinger Band acts as an SMA that serves as the center line, typically being calculated over 20-day periods.

B. Standard Deviation (SD)

Bollinger Bands’ Upper and Lower bands are calculated based on the standard deviation of price movements; their boundaries typically lie two standard deviations away from the Middle Bollinger Band.

These bands are used to demonstrate volatility and price levels visually and intuitively. Here’s how they work in technical analysis:

1. Volatility Measurement

To measure price volatility, traders can use it as a barometer – when volatility is high they widens, while when it falls they tightens – to identify periods of potential breakout or consolidation in price movements.

With the help of Bollinger Band traders always identify overbought and oversold conditions in the market. When the price touches or crosses the upper band, this may indicate overbuying; conversely, when the price crosses or touches the lower band it could indicate overselling and potentially an upward correction in price.

3. Price Trends

Traders often utilize Bollinger Bands to analyze price trends. When the price consistently travels above or below its respective band, this could signal an uptrend or a downtrend respectively.

Now that we understand what Bollinger Bands are and how they operate, let’s look at how to implement them into our trading strategies effectively.

Bollinger Bands Squeeze

A. Bollinger Bands Squeeze

When the Bands contract, this indicates low volatility – something traders often take as a signal for an upcoming price breakout. Be on alert as when these bands contract they could cause major market shifts!

B. Bollinger Bands Divergence

Divergences between price and Bollinger Bands can indicate potential trend reversals. For instance, if the price makes a lower low while the lower band makes a higher low, this could indicate a bullish trend change.

C. Confirmation with Other Indicators

To increase the accuracy of your trading decisions, Bollinger Bands should be used with other technical indicators like Relative Strength Index (RSI) or Moving Average Convergence Divergence (MACD). This approach may give additional support when making trading decisions.
