    Annotation In practice, there are problems for the solution of which it is required to find anomalies in the numerical series. Such tasks are found in various areas: in data science, machine learning, cybersecurity, algorithmic trading, etc. The article shows examples of how to quickly and efficiently find anomalies in numerical series using the modified Hampel method (Hampel F.R.) using sliding windows. To filter a number series for the presence of anomalies in it, it is proposed to use the Python implementation of the HampelFilter() function. The use of the created functions is possible, among other things, using the example of the problem of searching for outliers in stock data.
