Exponential Moving Average (EMA)

The Exponential Moving Average (EMA) is a widely used technical indicator in financial markets that helps to smooth price data and identify trends more effectively.

The EMA, a type of moving average, places greater weight on the most recent price data, making it more responsive to new information compared to the Simple Moving Average (SMA). This characteristic allows traders and analysts to better capture short-term price movements and trends. The Exponential Moving Average is calculated by applying a multiplier to the most recent closing price, adding it to the previous period’s EMA, and then dividing by the total number of periods. Commonly used periods for EMA calculations include 12, 20, and 50 days. Traders utilize this indicator to identify trend direction, potential entry and exit points, and to generate trading signals.

Customize EMA Length / Period / Sensitivity

When using the EMA technical indicator, you can fine-tune its responsiveness by adjusting the period parameter through our API. This parameter allows you to customize the number of candles considered in the EMA calculation. Choosing a shorter period makes the EMA more sensitive to recent price changes, offering a quick reaction to market movements. Conversely, selecting a longer period smoothens the EMA’s output, providing a more stable view of long-term trends. This feature enables you to tailor the Exponential Moving Average to align with your specific trading strategies and timeframes, thereby enhancing its effectiveness in various market conditions.

API parameters

Required String
The secret which is emailed to you when you request an API key.
Required String
The exchange you want to calculate the indicator from: binance, binancefutures or one of our supported exchanges. For other crypto / stock exchanges, please refer to our Client or Manual integration methods.
Required String
Symbol names are always uppercase, with the coin separated by a forward slash and the market: COIN/MARKET. For example: BTC/USDT Bitcoin to Tether, or LTC/BTC Litecoin to Bitcoin...
Required String
Interval or time frame: We support the following time frames: 1m, 5m, 15m, 30m, 1h, 2h, 4h, 12h, 1d, 1w. So if you're interested in values on hourly candles, use interval=1h, for daily values use interval=1d, etc.
Optional Integer
The backtrack parameter removes candles from the data set and calculates the ema value X amount of candles back. So, if you are fetching the ema on the hourly and you want to know what the ema was 5 hours ago, set backtrack=5. The default is 0.
Optional String
The chart parameter accepts one of two values: candles or heikinashi. candles is the default, but if you set this to heikinashi, the indicator values will be calculated using Heikin Ashi candles. Note: Pro & Expert Plans only.
Optional Boolean
true or false. Defaults to false. By setting to true the API will return a timestamp with every result (real-time and backtracked) to which candle the value corresponds. This is especially helpful when requesting a series of historical values using the results parameter.
New Optional Boolean
true or false. Defaults to true. By setting to false, the API will ensure that there are no candles missing. This often happens on lower timeframes in thin markets. Gaps will be filled by a new candle with 0 volume, and OHLC set the the close price of the latest candle with volume.
New Optional String
number or max. Use this parameter to access historical values on the past X candles until the most recent candle. Use max to return all available historical values. Returns an array with the oldest value on top and most recent value returned the last.
Optional Integer

Specify the EMA length – number of candles, from which the EMA will be calculated. Maximum is 350.

Please note that there might not be enough existing candles on a timeframe like the weekly if the symbol has not been trading for a very long time.

Default: 30

More examples

Let's say you want to know the ema value on the last closed candle on the 30m timeframe. You are not interest in the real-time value, so you use the backtrack=1 optional parameter to go back 1 candle in history to the last closed candle.
