🔍 What Are Bollinger Bands?

Created by John Bollinger in the 1980s, Bollinger Bands are a volatility indicator that forms a dynamic “envelope” around price. They consist of:

1. Middle Band: 20-period Simple Moving Average (SMA)
2. Upper Band: SMA + (2 × Standard Deviation)
3. Lower Band: SMA – (2 × Standard Deviation)

📌 Key Features:

• Adjust automatically to market volatility
• Work on any timeframe (1min to monthly)
• Effective for stocks, forex, and crypto

Why Traders Love Them:

✔ Visualize volatility (bands widen/narrow)
✔ Spot overextended prices (touches upper/lower bands)
✔ Identify trend strength (price riding a band)

🧮 How Bollinger Bands Are Calculated

Let’s break down the math (don’t worry – it’s simpler than it looks!):

1️⃣Calculate 20-day SMA

• Add last 20 closing prices ÷ 20

2️⃣Find Standard Deviation

• Measures how spread out prices are from average

3️⃣Plot Upper/Lower Bands

• Upper: SMA + (2 × SD)
• Lower: SMA – (2 × SD)

📊 Example: If SMA = $100 and SD = $5:

• Upper Band = $100 + (2 × $5) = $110
• Lower Band = $100 – (2 × $5) = $90

💡 Pro Tip: Most platforms calculate this automatically. Focus on interpretation, not calculation!
