Cross Over Stock Trading Algorithm

Sometimes I wonder if or when I should buy a stock, and I'll get a stock trading algorithm in my head. Would it beat holding the stock? How risky is it?

One way to access that is testing the algorithm on past market data. Here, I do just that.

• Use API to pull stock data
• Methods to analyze stock data
• Crossover trading concept

Crossover algorithm trading periods

While this Notebook follows another blog post, I made significant changes to the code and added better visualizations.

Stock Trading Algorithm Testing

• Test the Crossover trading algorithm on all the stocks in the S&P 500
• Analyze results
