Drawdown over Window (in percentage)

Unlike other scripts, which compare against the all time high, this allows you to specify the window over which the high should be searched.
If you want to compare against the all time high, just choose a long enough window.

In true TradingView spirit, the author of this script has published it open-source, so traders can understand and verify it. Cheers to the author! You may use it for free, but reuse of this code in a publication is governed by House Rules. You can favorite it to use it on a chart.
