median
Statistical Median
median(source, period)
Parameters
| Name | Type | Description |
|---|---|---|
source |
field | Data series to calculate median of |
period |
int | Number of periods for median calculation |
Formula
Median = Middle value when data is sortedExamples
// 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
float
Range
period must be 2-400
Notes
Less sensitive to outliers than mean/SMA and computationally more expensive; uses PERCENTILE_CONT(0.5) for calculation
