Pie chart fractional

Fractional shares - invest with $1

Fractional shares allow you to invest in a portion, rather than a whole share, of a company. Our API is flexible: you can complete a fractional trade using a quantity or dollar-based amount and we’ll convert it to parts of a full share.

Code sandbox

Test in a sandbox environment

Our sandbox environment (paper trading feature) simulates a real-time market where you can test your strategies before you invest your money. Alpaca’s paper trading feature has also become popular for schools and clubs around the world to host trading competitions.

Margin trading and short selling

Trading on margin allows you to trade and hold securities with a value up to 4X intraday and up to 2X overnight of your account equity. Alpaca currently has thousands of easy-to-borrow (ETB) securities that are available for short selling.
