A bundle is the primary way to interact with the Likely exchange. It is a package of up to 256 operations that represent your specific trading intent.

The Power of the Bundle

Traditional exchanges force you to manage multiple orders independently. If you want to hedge a position across two different markets, you have to send two orders and pray they both fill. On Likely, you put both trades in one bundle. If one of them can’t be filled, the entire bundle can be canceled automatically. You are never left holding “half” of a strategy.

What’s inside?


Smart Execution (Policies)

You are in total control of how the exchange handles surprises. For every operation in your bundle, you can set a Failure Policy:
  • Atomic (Revert Bundle): If this step fails, undo everything. Perfect for arbitrage.
  • Flexible (Ignore): If this step fails, just keep going.
  • Conditional (Revert Backward): If this step fails, undo what you just did and try the next part of your strategy.
  • Partial (Revert Forward): If this step fails, stop the bundle and cancel all future steps, but keep the ones that already succeeded.

Life of a Bundle

The journey from your screen to the exchange takes about 500ms:

Why Traders Love Bundles

  • Privacy: Your bundle details are private until they are matched. Bots can’t “sniff” your strategy.
  • Risk Protection: No partial fills means no “accidental” positions.
  • Priority Control: Tips allow you to prioritize value over speed.
  • Scalability: High-frequency traders can pack 256 actions into a single atomic update.
