Compared to Endless Mode, support more complete save data (funds, holdings, stock data, etc.)

Note: Multiplayer mode is still in Beta. Thank you for your patience and feedback; we will continue improving the experience for smoother and more stable online play.

Single-player mode was just the beginning— 👉 Multiplayer Beta is now live!

In each match, you will perform strategy operations with other players, using different techniques to compete in strategy. Each match is an independent experience, and players do not affect each other.

⚠️ Note

Each match = independent room; data resets after the match
Not a global unified market; not a continuously running exchange
Beta may experience connection instability or delays

💡 Tip

For stable play → wait for the official version
Want to help improve → join the Beta now

Fixed an issue where, after failing a level mode challenge and continuing in "Open Mode", meeting the conditions would not trigger a successful clearance.

1. Continue to optimize the logic for NPCs (Institutional Investors, Retail Investors) and fix the issue of endless decline after selling. 2. Change the unit for total shares and tradable shares from "share" to "lot", where 1 lot = 100 shares. 3. When price tracking is enabled, manually editing the price will automatically cancel price tracking. 4. Fixed the issue where quantity could not be manually edited after enabling price tracking.

1. Optimized the logic for NPCs (Institutional Investors, Retail Investors). 2. Fixed the issue where scrolling the mouse wheel could penetrate through other opened windows.

1. Added shortcut key functionality. You can now view or customize shortcut keys in the settings. 2. Fixed an issue where the level occasionally failed to clear even when the clearance conditions were met. 3. Optimized order placement by clicking on the market depth display. Removed price locking and automatic order submission.

Focus optimized the settlement UI for "Endless Mode". 1. Changed "Settlement" to "Save". 2. In the save interface, the savable content is now displayed more intuitively. (In Endless Mode, saving only preserves funds, not holdings.) 3. In the save interface, if holdings exist, an anti-misoperation feature has been added. You must first click "Abandon Holdings" before you can return to the title screen or exit the game. 4. Clicking "Save" will immediately save the data. 5. Data is automatically saved after each market close. Regarding the mechanics of Endless Mode: 1. Saving only preserves funds. 2. Holdings and the market reset at the start of each round. A "Free Mode" will be launched subsequently, which differs from the "Endless Mode" mechanics. It will allow saving not only funds but also holdings and the market. "Endless Mode" will continue to be adjusted and optimized in the future to increase its challenge and playability.

1. Fixed the issue where left-clicking to view intraday minute K-lines displayed incorrect content. 2. Fixed the issue of text overlapping when multiple indicators were displayed simultaneously.

1. Added intraday minute-level K-line charts, including 1-minute, 5-minute, 10-minute, 15-minute, and 30-minute intervals. 2. Added filter options for news/information. 3. Increased the auto-order submission time interval to 0.05s. 4. Fixed the issue where the KDJ indicator occasionally displayed errors.

1. Added the RSI technical indicator. 2. Added the BOLL technical indicator.

1. Added the KDJ technical indicator. 2. Optimized the display of the market depth window (order book). 3. Fixed the issue where the colors of moving averages (MA) were displayed incorrectly during filtering. 4. Performance optimization: fixed lagging issues that occurred during the late trading phase.

1. Added the MACD technical indicator. 2. Added star rating filtering for news. 3. Fixed the stuttering issue when using time fast-forward while holding multiple stocks. 4. The holdings list will prioritize displaying the currently selected stock. 5. Optimized automatic order submission: orders will be paused when time is paused, and no orders will be submitted during the morning and late auction sessions. 6. Optimized order submission: added a price tracking feature that can track the highest price, lowest price, and latest price (via the button next to the stock name).

1. Added K-line zoom in and zoom out functionality. 2. Added the ability to adjust values by scrolling the mouse wheel when hovering over a price or quantity in the trading interface. 3. Added the functionality that a left-click on the order book automatically opens the trading interface and pre-fills the order price and quantity. 4.
