# Glossary - K
### Kaufman's Adaptive Moving Average (KAMA)
Developed by Perry Kaufman, Kaufman's Adaptive Moving Average (KAMA) is a moving average designed to account for market noise or volatility. This trend-following indicator can identify the overall trend, time turning points, and filter price movements. See our ChartSchool article on [KAMA](/table-of-contents/technical-indicators-and-overlays/technical-overlays/kaufmans-adaptive-moving-average-kama.md).
### Keltner Channels
Similar to Bollinger Bands, Keltner Channels form volatility-based bands above and below an exponential moving average of price. Channel direction and price breakouts above or below the channels can be used to identify trend reversals. See our ChartSchool article on [Keltner Channels](/table-of-contents/technical-indicators-and-overlays/technical-overlays/keltner-channels.md).
### Key Reversal Day
A one-day chart pattern where prices sharply reverse during a trend. In an uptrend, prices open to new highs and then close below the previous day's closing price. In a downtrend, prices open lower and then close higher. The wider the price range on the key reversal day and the heavier the volume, the greater the odds that a reversal is taking place.

## 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://chartschool.stockcharts.com/table-of-contents/glossary/glossary-k.md?ask=&goal=
```
`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.
