median

Parameters

Statistical Median - median(source, period)

Calculates the median (middle value) over a period. More robust to outliers than mean.

• source (source): Data series to calculate median of
• period (int): Number of periods for median calculation
• Common values: 14, 20, 50

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
