DEMA

Double Exponential Moving Average Indicator​

Description​

The DEMA (Double Exponential Moving Average) worker calculates the double exponential moving average based on a list of prices. This indicator is commonly used in financial markets to analyze trends and make informed trading decisions.

What does this worker do?​

This worker takes a list of prices and a time period as input, and returns the double exponential moving average of the prices over the specified time period. The DEMA indicator helps to smooth out price fluctuations and provide a clearer picture of the market trend.

How to interpret the results​

The DEMA indicator can be used to:

  • Identify trends: A rising DEMA indicates an uptrend, while a falling DEMA indicates a downtrend.
  • Signal buy and sell opportunities: When the DEMA crosses above or below the price, it can be used as a buy or sell signal.

Parameters​

The following parameters can be passed to the DEMA worker:

{
  "dataExp": {
    "type": "string",
    "description": "List of prices"
  },
  "timeperiod": {
    "type": "number",
    "default": 30
  }
}

Parameters List​

  • dataExp:
    • Type: string
    • Description: List of prices
  • timeperiod:
    • Type: number
    • Description: Time period for the calculation
    • Default: 30

Example Use Case​

To calculate the DEMA for a list of prices with a time period of 30, you can pass the following parameters:

{
  "dataExp": "[10.0, 12.0, 15.0, 13.0, 14.0]",
  "timeperiod": 30
}

This will return the double exponential moving average of the prices over the specified time period.
