Usually when you see algorithms that generate ridiculous returns like yours, the first thought turns to leverage, however when you are buying Apple you can get ridiculous returns with out over leveraging yourself! That being said I did check your leverage and it isn't running away. If you want to reduce drawdown and beta I would suggest moving away from buying and selling AAPL and SPY exclusively. This is why folks diversify their portfolios, to reduce the risk brought on by carrying a few stocks. Check out some other strategies involving multiple securities.

See the sample algorithms for ones that use multiple securities.

You may also want to make sure your max position size is equal to your minimum to avoid directional bias

I think the question should be, what is your goal/strategy here overall. The return looks great, but the real answer is that you have just dampened the actual return of Apple over that time frame (which was about 7500% or so). You certainly got your result with a much lower beta, but think you should consider trying to accentuate your strategy more specifically.

Just a thought, take it or leave it :).

Cheers

What is a good way for an algorithm to know what its beta is?

I like your question André, running beta value in a variable. In Zipline I think Treasuries data is pulled in for the calculation if I'm not mistaken.
