Backtesting

If you followed the previous section of the guide on using AI to create a trading strategy, you would have used the testing strategy template. This guide will help you understand how to effectively backtest your strategy to ensure it works well under various market conditions.

Introduction to Backtesting

Backtesting involves running your trading strategy on historical data to evaluate its performance. It helps you identify periods when the strategy works best and adjust it accordingly. For example, your strategy might perform exceptionally well during bullish Bitcoin trends.

Step-by-Step Guide to Backtesting Your Trading Strategy

Step 1: Understanding the Date Range in Your Strategy

In your trading strategy code, you will find parameters that define the date range for backtesting. These parameters are critical for setting the start and end dates of your backtest.

1. Locate Date Parameters:

• Find the lines in your Pine Script code that include fromDay, fromMonth, fromYear, toDay, toMonth, and toYear.

• These parameters define the start and end dates for your backtest.

Example Code:

// BACKTESTING RANGE

// Start of back testing (Change defval numbers for day, month and year. This is when back testing starts)
fromDay = input.int(defval=1, title="From Day", minval=1, maxval=31)
fromMonth = input.int(defval = 12, title = "From Month", minval = 1, maxval = 12)
fromYear = input.int(defval = 2023, title = "From Year", minval = 1970)

// End of back testing (Change defval numbers for day, month and year. This is when back testing ends)
toDay = input.int(defval = 7, title = "To Day", minval = 1, maxval = 31)
toMonth = input.int(defval = 12, title = "To Month", minval = 1, maxval = 12)
toYear = input.int(defval = 2024, title = "To Year", minval = 1970)

1. Set the Date Range:

• Adjust the defval (default value) numbers to set your desired start and end dates for the backtest.

• Ensure the toDay, toMonth, and toYear are set to the current date to get the most recent data if that is what you'd like to do.

Step 2: Viewing Backtest Results

1. Check the Strategy Tester Tab:

• In TradingView, click on the "Strategy Tester" tab, located at the bottom of the screen next to the "Pine Editor" tab.

• This tab displays the performance of your strategy over the specified date range.

1. Analyze Different Timeframes:

• Test your strategy across different chart timeframes. To change the timeframe, click on the timeframe dropdown menu at the top left of the TradingView screen (e.g., 1D for one day, 1H for one hour, 15 for fifteen minutes).

• Select a different timeframe to see how it affects the strategy’s performance.

• Note that higher frequency trading (e.g., on a 15-minute chart) may incur higher transaction costs, especially with Ethereum due to gas fees.

Step 3: Troubleshooting Backtest Issues

1. No Trades Generated:

• If your strategy doesn't generate any trades, there might be an issue with the strategy's criteria or the date range.

• Double-check the backtest date range to ensure it encompasses a period when the token was actively traded.

Example Issue:

• If the toYear is set before the token's creation date, no trades will be generated.

1. Adjusting the Date Range:

• If no trades are being generated, try extending the toMonth and toYear to the current date.

• Save the changes and rerun the backtest.

Example Fix:

toMonth = input.int(defval = 12, title = "To Month", minval = 1, maxval = 12)
toYear = input.int(defval = 2024, title = "To Year", minval = 1970)

Edit "toMonth" to 12 by editing Defval

Step 4: Interpreting Backtest Results

1. Evaluate Profitability:

• Look at key metrics such as net profit, maximum drawdown, and win rate in the Strategy Tester tab.

• Note that the strategy backtest figures the metrics if $1000 is entered into each trade.

• Compare results across different timeframes to determine the most profitable settings.

1. Example Analysis:

• If a strategy used $1,000 per trade and resulted in a $6,000 profit, it indicates a 6X return.
