## Ulcer Index (UI)

### What is 'Ulcer Index - UI'

A technical indicator that measures downside risk, in terms of both depth and duration of price declines. The Ulcer Index (UI) increases in value as the price moves farther away from a recent high, and falls as the price rises to new highs. The indicator is usually calculated over 14 days, with the UI showing the percentage drawdown a trader can expect from the high over that period.

### Explaining 'Ulcer Index - UI'

Developed by Peter Marin and Byron McCann in 1987 for analyzing mutual funds, the indicator only looks at downside risk, not overall volatility like standard deviation.
