range(max_source, min_source, period)
Parameters
| Name | Type | Description |
|---|---|---|

```
Examples
// 14-period high-low range expanding (increasing volatility)
x = range(high, low, 14); x > x[1];
// narrow 20-period close range (consolidation)
range(close, close, 20) < 5;
// range compressed to 50% of average
range(high, low, 14) < sma(range(high, low, 14), 50) * 0.5;
Returns
Difference between maximum and minimum over the specified period ## References - TradingView: Calculate as `ta.highest() - ta.lowest()` ## Notes - Used in Stochastic, Williams %R, and other oscillators - Measures volatility/spread over period - Always non-negative (max - min ≥ 0)
