Why TickAtlas

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.

Pre-Calculated, Redis-Cached

Indicator values are computed server-side on every new candle. Your app queries the result — no TA library, no candle history needed.

7 Timeframes

M1, M5, M15, M30, H1, H4, D1 — the same endpoint serves scalpers and position traders alike.

Forex, Crypto, Commodities

EURUSD, GBPUSD, XAUUSD, BTCUSD, USDJPY — data available for every symbol in our data.

One Request. Instant Data.

Frequently asked questions

What developers ask first.

Straight answers on limits, coverage and how the endpoint behaves in production.

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 our 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 (or RSI_14) in separate requests and combine the signals in your bot. Each indicator call is independent and returns cached data.

Is historical DEMA data available?

Yes — use GET /v1/indicator/history with indicator=DEMA_20. Depth is set per timeframe and is the same on every plan — 45 days on D1, 30 days on H4, 14 days on H1.
