What is the DEMA API?
Double Exponential Moving Average (DEMA) applies two passes of EMA smoothing using Patrick Mulloy's formula: DEMA = 2×EMA - EMA(EMA). The result is a moving average that hugs price more closely than a standard EMA at the same period, giving trend-following bots earlier crossover signals and fewer false lagging entries. Our API delivers the pre-calculated DEMA(20) value so you never need to implement the formula yourself.

Frequently Asked Questions
What is the DEMA formula?
DEMA = 2 × EMA(n) − EMA(EMA(n)), where n is the period. The double-smoothing step cancels out most of the lag in a regular EMA. Our API computes this using broker candle data with n=20.
Is DEMA better than EMA for all strategies?
Not necessarily. DEMA reacts faster, which helps trend-following entries but can produce more whipsaws in ranging markets. It works best combined with a volatility or trend-strength filter like ADX.
Can I use DEMA alongside other indicators in the same strategy?
Yes. Query DEMA_20 and ADX_14 (or RSI_14) in separate requests and combine the signals in your bot. Each indicator call is independent and returns in under 100ms.
Is historical DEMA data available?
Yes — use GET /v1/indicator/history with indicator=DEMA_20. Starter plan provides up to 30 days on H1+; Pro and Enterprise plans extend to 45 days.
