📈 Bollinger Bands in Forex Trading

Bollinger Bands are a popular technical analysis tool used by forex traders to measure market volatility and identify potential buy and sell opportunities. Created by John Bollinger in the 1980s, this indicator is especially useful for spotting price breakouts and reversals.

🔧 What Are Bollinger Bands?

Bollinger Bands consist of three lines plotted on a price chart:

Middle Band (SMA):

A 20-period Simple Moving Average (SMA) of the price.

Upper Band:

SMA + (2 × standard deviation)

Lower Band:

SMA − (2 × standard deviation)

The standard deviation measures volatility, so when the market is volatile, the bands widen; when the market is calm, the bands contract.

💡 How to Use Bollinger Bands in Forex

1. Identifying Overbought and Oversold Conditions

Price near the upper band: Market may be overbought → Possible sell opportunity.

Price near the lower band: Market may be oversold → Possible buy opportunity.

⚠️ Don't rely on Bollinger Bands alone — confirm with other indicators like RSI or MACD.

2. Breakout Signals

When price breaks above the upper band, it can signal a strong bullish breakout.

When price breaks below the lower band, it may suggest a strong bearish breakout.

⚠️ Bollinger Bands do not predict direction — they highlight volatility spikes.

3. The Squeeze

When the bands contract tightly, it signals a low-volatility period.

This often precedes a sharp breakout, either up or down.

🔍 Traders watch for squeezes as potential setups for major price moves.

📊 Example Strategy

Bollinger Band + RSI Strategy

Wait for price to touch lower band.

Check if RSI < 30 → Confirms oversold.

Look for reversal candle pattern → Enter buy trade.

Place stop-loss below recent low, target middle band or upper band.
