The Moving Window processors calculate a statistic, such as the average, maximum, or minimum, over a sliding window of a single input's values.

## Why use the Moving Window processors

Use one of the Moving Window processors when you need a continuously updating statistic over the most recent values of a single input, rather than a one-time calculation across a fixed range.

## How it works

Choose the processor that matches the statistic you need:

- **Moving Average** calculates the average of the input's values within the window.
- **Moving Maximum** returns the maximum value within the window.
- **Moving Minimum** returns the minimum value within the window.

Connect the input to the processor using an **events** connection, and connect the processor to the output using an **events** connection as well.

By default, the processor operates on each input's `value` field. Use **Field Name** only if your input uses a message-type payload or a field name other than `value`, for example `deviceID` or `success`.

## Parameters

| **Parameter**   | **Details**                                                                                                                                    |
| --------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| Processing Type | The data type of the value being processed: `float`, `signed integer`, or `unsigned integer`.                                                  |
| Window Size     | The window (in seconds) over which the processor calculates its statistic.                                                                     |
| Field Name      | The field the processor operates on. Leave this unchanged unless your input is a message-type payload or uses a field name other than `value`. |
