# How to Create a New Backtest?
1. **Go** **to the details page of the strategy you want to backtest and click “Create a New Backtest.”**
2. **Choose the symbol you want to backtest.**
3. **Choose the Test Date Range**
* You can choose to select last 3 months, last 6 months, and last year.
* Or you can select based on crypto and macroeconomic cycles, like “Bitcoin Bullish,” to backtest the strategy during historical Bitcoin bull markets.
* You can also customize your time range:
First, input the new date range name, e.g., “2023 Consolidation Phase.”
Then, click the red tag to select the time interval.
You can add a range from date X to date Y, or choose the last X (hour, day, week, month, year).
4. **Confirm the Interval**
The backtest will be performed using the bar chart interval of your selection, such as 1 hour, 1 day, or 1 week.
5. **Advanced Settings (Optional)**
Click the button in the top right corner for advanced settings where you can modify the strategy's parameters and backtest settings.
6. **Start Backtesting**
After setting up, click “Start Backtest.”
You’ll then see the performance of the strategy for the custom time range you selected.
