The landscape of retail investing has been fundamentally reshaped by two powerful forces: commission-free trading platforms and sophisticated automation tools. In this era of rapid technological advancement, staying ahead means ensuring that the tools you use are connected by the most robust and functional infrastructure available. 

That is why the StockHero team is thrilled to announce a significant leap forward in our partnership with one of the most popular and dynamic brokerages in the market. On November 12, 2025, we officially rolled out the new Webull 2.0 API connection, an infrastructure designed from the ground up to deliver improved functionality, expanded trading capabilities, and a more resilient experience for every user. 

This update is more than just a minor revision; it’s a commitment to supporting the ambitious strategies of our traders, ensuring they have access to the full spectrum of Webull’s offerings directly through the StockHero bots.

Let’s dive into the exciting features of the 2.0 API.

Webull: Democratizing Financial Markets

Webull is a leading, globally recognized financial technology company known for its state-of-the-art, commission-free trading platform. Catering to both novice and experienced investors, Webull offers trading in stocks, options, ETFs, and cryptocurrencies, often featuring extended trading hours and powerful analytical tools. Its appeal lies in democratizing access to complex financial markets through a highly mobile and feature-rich application. For an automated trader, Webull provides the liquidity and the infrastructure necessary to execute strategies at speed. Its commitment to advanced technology makes it a natural partner for an innovative automation platform.

Key Enhancements in Webull 2.0

The Webull 2.0 API is a major upgrade that directly addresses the needs of our most sophisticated users, introducing features that provide greater flexibility and access to more capital types. This is about allowing your automated strategies to operate with fewer constraints and across a wider range of investment goals.

Expanded Account and Trading Capabilities

The most significant enhancements in the Webull 2.0 API center on account access and execution timing:

  1. Support for Cash, Margin, and Roth Accounts: Prior limitations on account types are now history. With 2.0, traders can connect and manage bots across all three major account types. The inclusion of Roth accounts is particularly impactful, enabling users to deploy automated strategies within a tax-advantaged retirement structure—a major strategic advantage for long-term automated investing. Furthermore, the enhanced support for Margin accounts allows for more complex, leverage-based strategies to be accurately executed by your bots.
  2. Extended-Hours Trading Order Execution: The Webull platform is well-known for offering trading outside of standard market hours. The new 2.0 API ensures that your StockHero bots can now fully capitalize on this feature. This capability provides a competitive edge, allowing bots to react instantly to overnight news, post-market earnings reports, and pre-market price action, which often dictates the trend for the trading day. This feature alone drastically expands the operational window and potential profitability for many strategies.

The Strategic Transition: Minimizing Disruption

The transition to a new infrastructure can often be disruptive, but the StockHero team has taken steps to ensure users can move at their own pace.

The Webull 2.0 API is introduced as a completely new brokerage connection. This means you are not required to disconnect from the existing Webull 1.0 API to begin testing the new one. This strategic decision allows for a smooth, self-paced transition. Users can connect to 2.0, keep their existing 1.0 connection active, and gradually migrate their bots and capital.

However, users should be aware that the Webull 1.0 API will eventually be phased out once the 2.0 version is fully stable and exits its beta period. Therefore, while the move is voluntary now, it will become mandatory in the near future to maintain connectivity. In preparation for this, users will need to perform a one-time connection to the new 2.0 API to link their Webull account again under the new infrastructure.

The Beta Phase: A Call for Community Partnership

To ensure the long-term reliability and robustness of the new API, the Webull 2.0 API is currently in its BETA phase.

What does this mean for the user? While the API has undergone extensive internal integration and testing by the StockHero team, real-world usage is the critical next step in validating its performance under diverse market conditions and bot strategies. As a result, users may experience occasional issues or unexpected behavior during this initial period.

We strongly encourage our community to participate in this validation process. Our team’s priority is to squash any bugs related to this new API as quickly as possible. We ask users who test the 2.0 connection to:

  1. Test with Limited Capital: Start by deploying only a few bots and limiting the capital allocated to the 2.0 connection.
  2. Report Issues Promptly: Email our support team immediately with any bugs or issues encountered. Priority is given to reports related to the Webull 2.0 API.

The expected beta period is projected to last between one to six months, depending directly on the volume and frequency of incidents reported by the community. Your participation is what accelerates the process of making the 2.0 API the stable, reliable powerhouse it is designed to be.

Wrapping Up

The release of the Webull 2.0 API is a landmark moment for StockHero users. It significantly enhances the capabilities of our platform, offering crucial support for Cash, Margin, and Roth accounts, alongside the strategic benefit of extended-hours trading. This new infrastructure promises greater stability, expanded flexibility, and a more comprehensive set of tools for automated trading success.

While we are in the beta phase, we urge all users to start the transition now. Connect the new Webull 2.0 API today, test its capabilities with a portion of your strategy, and help us finalize this essential upgrade.
