# Weis Wave Volume

The algorithm lets us:

* Look at chains of price bars as alternating waves rising and falling.
* Take the volume of each wave as the total volume of the bars that make it up.

These indicators show up in the lower part of the chart as a histogram of same- (for rising volumes) and different-colored (for falling volumes) waves.

The indicator shows trade intensity over a set period, demonstrating supply and demand for the asset in question and potentially signaling that it is time to activate positions.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.tiger.com/english/windows/chart/main-indicators-in-chart-window/weis-wave-volume.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
