## General When backtesting your trading bots and signals on historical data, you can use custom time ranges called **Timeframes**. Timeframes allow you to test your signals on specific time ranges of an asset, such as a bull market, bear market, or sideways market. Another good use case for Timeframes is to test your signals on specific events, such as a stock market crash or a cryptocurrency bubble period. \[PIC] todo

## Groups Timeframe Groups allow you to organize your Timeframes into categories. As an example, you could create a Timeframe Group called "Dip Buy" and add Timeframes for specific market dips of assets that you want to test your signals on. \[PIC] todo
