STDDEV

Overview​

The STDDEV worker calculates the Standard Deviation, a widely used indicator in financial markets to measure the volatility of a security's price.

Description​

The Standard Deviation is a statistical measure that represents the dispersion of a set of data points from their mean value. In the context of financial markets, it is used to gauge the volatility of a security's price over a given period.

What does this worker do?​

The STDDEV worker takes a list of prices and calculates the standard deviation over a specified period, providing a measure of volatility. This can be useful for:

  • Identifying potential trading opportunities
  • Setting stop-loss levels
  • Evaluating the risk associated with a security

How to interpret the results​

The standard deviation value returned by the worker represents the volatility of the security's price over the specified period. A higher value indicates greater volatility, while a lower value indicates lower volatility.

Parameters​

The STDDEV worker accepts the following parameters:
