Multi-leg (Level 3) options are officially LIVE in our Trading API and dashboard 🎉

You can now trade advanced options trading strategies including: straddles, strangles, iron butterflies, iron condors, and various spreads (like credit, debit, and calendar).

These advanced strategies may help investors:

1. Capitalize on market volatility, range-bound price movements, and directional trends.
2. Increase efficiency by combining multiple options contracts into one single trade.
3. Improve risk management by ensuring all legs are executed simultaneously– shielding them from partial fills and unexpected market shifts.

And with multiple paper accounts, you can test various strategies at the same time before taking them live.

Orders that would execute at an invalid price will be automatically canceled.

Added a sentence “ On all orders (regardless of commission type), the commission charged will be prorated on each execution if the order has multiple executions. For instance, if 10% of the order is filled on one execution then the commission on that execution will be 10% of the total commission.”

The old announcements endpoint has been deprecated in favour of the more recent corporate actions endpoint. The new endpoint offers more structured response (different schema for each corporate action type) and better overall data quality.

The version of the new endpoint has been increased from v1beta1 to v1. This means that we now promise backward compatibility guarantee for the endpoint: we will not introduce breaking changes. The previous v1beta1 version can still be used, so no migration is required if you've already been using the endpoint.
