Formula
```
Median = Middle value when data is sorted
- If N is odd: median is the middle value
- If N is even: median is average of two middle values
```Examples
// price above 20-period median
x = median(close, 20); close > x;
// volume above median (outlier-resistant)
volume > median(volume, 50);
// median price rising
median(close, 20) > median(close, 20)[5];Returns
Median value from the period ## Notes - Less sensitive to outliers than mean/SMA - Computationally more expensive than mean - Uses percentile_cont(0.5) for calculation
