Aaron,

1) Your algorithm purchases 60 shares of Apple stock, every minute the market is open, for several years.
2) Apple stock increased in price during that time period.

Quantopian doesn't stop you from ordering more stock than you have money to purchase. So you likely owned billions of dollars in stock, most of that bought with money your account didn't have.

Keep reading the documentation and experimenting. That is the same way we are learning! :)

Cheers,

Tristan

Actually, I am also pretty sure you will also run out of Apple stocks to buy ... :D

Okay, thanks for the feedback. :D

Is there a code that prevents the algorithm from leveraging?

You can use order_target functions to seek to target positions, instead of mechanically ordering X shares each bar.

Also, you can use context.account.leverage to track your algo's leverage. Here's an example:
