Sharing algorithms

Clone a strategy, test it yourself, and share what you build.

Members can share their algorithms. A shared algorithm shows its code, its description, its versions and the backtests run on it, so you can read exactly what it does and test it before you trust it.

Browse and clone

• Community Shared Algorithms shows when you open Algorithms from the top menu. Each card shows the author, a short description, and totals from the backtests run on it.
• Open a card to read the description and the code, and to run your own backtests and optimizations on it. These use your compute units.
• Click Clone to copy it into your own algorithms as “Copy of …”. Choose which shared version to copy; the window warns you if it is not the newest. Your first save starts your own version history.

The totals on a card add up every backtest anyone has run on the algorithm, so “months backtested” can be far more than the calendar time covered. They describe past tests, not future results.

Share your own

Click the share icon next to the algorithm in your algorithms list, or the share control in the editor. You can:

• Share the current version only.
• Share the current version and turn on sharing, so every version you save from now on is shared too.
• Turn on sharing only, so the next version you save is the first one shared.

When you share an algorithm, other members can read its description and the code of every shared version, and run backtests on it. The results of their backtests are shared with you.

Before you share

• Sharing cannot be undone. A shared version stays shared. Turn off sharing stops new versions being shared, but does not hide versions already shared. Deleting the algorithm is the only way to withdraw it.
• Keep secrets out of your code. Never put an API key, a password or anything personal in an algorithm you might share.
