# Price Step Filter

The "Price Step" filter allows the algorithm to place orders only if the price step (as an absolute percentage of the current price) is within the specified range.

### How to Use

Specify the price step range in percentages from minimum to maximum value.

**How it works:** The algorithm checks whether the trading pair's price step falls within the specified range. If yes — orders are placed, if no — the pair is excluded from trading.

**Example:** If you set a range from 0% to 0.25%, the algorithm will only work on pairs where the minimum price change is no more than 0.25% of the current price.

### What is Price Step

**Price Step** is the minimum possible price change for an instrument on the exchange. It determines how much the price can change between two orders.

**Why this is important:** To avoid trading on low-volatility coins, use a small price step.

### Application

Enable the filter and set the range. The algorithm will only work with pairs whose price step meets your requirements.

## 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://guide.moontrader.com/en-moontrader-docs/trading/trading-algorithms/general-algorithm-settings/price-step-filter.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.
