# Commodity Channel Index

## What is CCI?

A versatile indicator that measures the current price level relative to an average price level over a given period.

## Think of it like this

Like measuring how far a runner has strayed from the average pace - too far ahead or behind may signal a return to normal.

## Formula

```
CCI = (Typical Price - SMA of TP) ÷ (0.015 × Mean Deviation)
```

- **Typical Price**: (High + Low + Close) ÷ 3
- **SMA of TP**: Simple moving average of typical price
- **Mean Deviation**: Average absolute deviation from SMA

## Why it matters

- Identifies cyclical turns in commodities and stocks
- Measures price deviation from statistical mean
- Works on any timeframe
- Good for identifying new trends

## What's a good value?

| Range | Rating | What it means |
|---|---|---|
| > +100 | Overbought | Strong uptrend or overextended |
| 0 to +100 | Bullish | Positive momentum |
| -100 to 0 | Bearish | Negative momentum |
| < -100 | Oversold | Strong downtrend or overextended |

## Real-world example

CCI crossing above +100 from below suggests a new uptrend may be starting.
