# Query & Filter Builder
> Learn about the powerful Query & Filter Builder component that allows you to create custom trading signals based on specific conditions.
## Introduction
The Query & Filter Builder allows you to easily create custom trading signals via a **user-friendly drag-and-drop interface - without any code experience**.
You can define and combine criteria based on hundreds of conditions, such as realtime OHLCV data (i.e. price, volume), social media mentions, news feeds, technical indicators, candlestick patterns, and more.
## How it works
Your final query (all the criteria you set) are constantly checked by the bot, and trades are executed automatically when all the conditions are met.
## Example
Let's say you want to create a criteria that triggers a buy signal when Elon Musk tweets about DOGE. All you need to do is to create a new filter criteria that listens to Elon Musk's X account and triggers a buy signal when a tweet is detected.

Now let's say you want to also check the price of DOGE and only trigger the buy signal when the price is above a certain threshold. You can easily add this condition to your query.

* **Custom Variables**: Define custom variables that can be used in your criteria.
* **Custom Functions**: Define custom functions that can be used in your criteria.
**Tip**: In order to use the advanced features, you need to write your own code bot using our [Bot SDK](/sdk-reference/introduction).
