Key Benefits:

• Confidence Boost: If a strategy worked in the past, it might work in the future.
  
  

• Identify Weaknesses: Spot flaws before real losses.
  
  

• Improve Strategies: Fine-tune for better results.
  
  

How Does Backtesting Work?

Here's the step-by-step idea:

1. Build a Strategy: For example, Buy when the stock price moves above the 50-day average.
   
   

2. Use Historical Data: Get past price movements.
   
   

3. Run the Test: Apply your strategy to that data.
