DMI Difference Oscillator: Direction from Plus DI Minus Minus DI

Summary

The DMI Difference oscillator represents directional movement by subtracting the minus directional indicator from the plus directional indicator. A positive difference indicates that plus DI is larger, while a negative difference indicates that minus DI is larger; the description colors upward movement blue and downward movement red. The only stated input is the ADX calculation period, which determines the period used for the directional indicators.

The document gives the core calculation but does not explain signal thresholds, smoothing beyond the ADX period, trade entries or exits, or risk management. It contains no examples, backtests, or performance evidence, so it teaches the indicator’s construction and visual interpretation rather than establishing a complete strategy. Its use as a trading signal would require separate testing and context.

Key ideas

• The oscillator is calculated as plus DI minus minus DI.
• Positive and negative values distinguish which directional indicator is larger.
• The display uses blue for upward movement and red for downward movement.
• The ADX period is the indicator’s only stated input, and no strategy validation is provided.
