Dual Ulcer Index Indicator

The Dual Ulcer Index Indicator is a unique and powerful risk-analysis tool designed to measure downside volatility in financial markets. Originally developed in 1987 by Peter Martin and Byron McCann, this indicator focuses on tracking drawdowns, helping traders better manage risk—especially in trending markets.

Unlike traditional volatility indicators, the Dual Ulcer Index emphasizes downside risk, making it particularly useful for traders holding long positions.

What is the Dual Ulcer Index?

The Dual Ulcer Index measures the depth and duration of price declines from recent highs. It is based on the principle that upward momentum is profitable, while downward movements represent risk.

This indicator can be applied to:

• Forex markets
• Stocks and indices
• Commodities
• Any timeframe (Scalping to long-term trading)

A key advantage is that it can also be interpreted in reverse, making it flexible for both rising and falling markets.

How Does the Dual Ulcer Index Work?

The indicator evaluates how far price moves away from its recent highs and how long it stays there.

Key Signals:

• Rising Index → Price is falling sharply (increasing risk)
• Falling Index → Price is recovering (decreasing risk)
• Near Zero → Strong uptrend with consistent higher highs

Behavior Summary:

• Spikes during sharp drawdowns
• Declines during recoveries
• Stays low in stable uptrends

How to Use the Dual Ulcer Index Indicator

The Dual Ulcer Index is primarily used for risk management and Trend Confirmation.

When to Exit or Be Cautious

• If the index starts rising while you're in a long trade, it signals increasing downside pressure
• A sharp increase suggests:
  • Consider exiting the trade
  • Tighten stop-loss levels

When to Hold or Add Positions

• If the index is falling, it indicates recovery and strength

Trading Example
