## **What is backtesting in Lunar?**

Lunar backtesting allows traders to assess how a strategy might have performed historically, offering crucial insights for refining strategies before actual implementation.

**Key Components**

* **Historical Data Analysis**: Simulate trades by applying defined strategies to the past price data of coins.
* **Strategy Development**: Develop trading strategies using patterns, settings, and custom timeframes aligned with your usual trading habits.
* **Performance Assessment**: Lunar provides a custom CSV file detailing the performance of all coins, facilitating a thorough review of the strategy's outcomes.

By leveraging these components, Lunar enables traders to evaluate the potential profitability of their strategies using comprehensive historical data analysis.

## How to run backtesting

Ensure you have a task with your preferred settings ready for backtesting. Once prepared, click the rewind button next to the copy of the task you want to test.

Clicking will open a custom timeframe panel, allowing you to select the desired timeframe for backtesting. Click at the top of a column or at the start of a row to select the entire row or column.

When you're ready, click "Start Backtesting". You can backtest up to 5 times per hour (we will increase the limit if everything will be fine). The landing simulation will occur within a range of 0 to 1.
