Double exponential moving average
DEMA combines a SMA-seeded EMA and an EMA of that EMA as 2×EMA − EMA-of-EMA.
Plain-language meaning
DEMA combines a SMA-seeded EMA and an EMA of that EMA as 2×EMA − EMA-of-EMA.
Why it is useful
Double exponential moving average is useful as descriptive evidence when it is compared on the same definition, source, period, unit and exact listing. It is one input to research, not a verdict.
Where it appears in XMarketRadar
Look for Double exponential moving average in Advanced Chart settings, indicator panels, screeners and technical research for the selected listing and bar interval.
How it is calculated or sourced
XMarketRadar calculates DEMA = 2×EMA(price) − EMA(EMA(price)); each EMA stage uses its own SMA seed and restarts after an interior unavailable value.
Inputs, period and unit
Read the disclosed inputs or source, observation period, bar interval, unit, native currency and scale. A value without its source and as-of context is incomplete; unlike units must not be combined.
Worked example
Illustrative only: a user reviews Double exponential moving average over a stated 20-bar or FY2026 period, checks the displayed source, unit and as-of date, and keeps an absent field as — rather than guessing 0.
What high and low mean
A higher or lower Double exponential moving average value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.
Positive, negative and genuine zero
Positive and negative Double exponential moving average values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.
Limitations and common mistakes
Double exponential moving average may differ by provider definition, observation time, instrument and venue. Common mistakes are dropping units or dates, comparing unlike scopes, and treating a missing value as zero.
Market-specific differences
The concept is used across all supported markets, but currency, price scale, session calendar, source field and regulatory definition can differ. XMarketRadar preserves the exact exchange context.
