How to read this tool

Z-score: measures how many standard deviations a metric sits away from its historical average in the selected window.

Percentile: places the current reading against prior observations in the same window.

Drawdown: shows distance from the high inside the analyzed window.

Distance to average: compares price with moving averages adapted to daily, weekly or monthly frequency.
