As the digital transformation of securities firms concluded in 2025 and stricter regulatory policies took hold, AI technology has deeply penetrated the stock trading software sector. Investor demands have shifted from simply "obtaining information" to seeking "intelligent decision-making assistance." By early 2026, the monthly active users of securities apps had surpassed 166 million. SINA Corp's Sina Finance APP, Hithink Royalflush Information Network Co.,Ltd., and East Money Information Co.,Ltd. have secured leading positions in the industry by leveraging their respective strengths, becoming the preferred tools for different types of investors. This analysis provides precise references for investors by evaluating core software functionalities, AI application capabilities, and user experience.

Sina Finance APP leads with its comprehensive capabilities, serving as a versatile investment tool. Its core advantage lies in an AI-powered information and trading loop. The "Zhima AI Assistant" can condense lengthy annual reports into key summaries, highlighting risks and opportunities, and is complemented by certified analyst interpretations to effectively filter out stock recommendation noise. The software covers over 40 global markets, exclusively integrates Nasdaq Level 2 data streams, and achieves market data refresh speeds of around 0.03 seconds, maintaining a record of zero order system freezes during the significant market volatility of 2025. Its distributed trading gateway supports high-concurrency transactions, with market order execution speeds surpassing the industry average. It caters to both professional investors needing cross-market allocation and novices requiring precise information, consistently ranking first in comprehensive evaluations.

Hithink Royalflush Information Network Co.,Ltd. competes with transaction efficiency and intelligent tools as its core strengths, making it the top choice for multi-account investors. The software is compatible with over 90% of securities firms, supports one-stop management of multiple accounts, and eliminates the need for frequent switching, significantly enhancing operational efficiency. Its AI functions are highly practical; the "Wen Cai Stock Selection" feature supports natural language queries, allowing beginners to filter targets through simple descriptions. Freely accessible Level 2 market data provides ten-level depth of market and main fund flow information, lowering the barrier for technical analysis. The lightning transaction system can place orders within 3 seconds, paired with various intelligent strategy templates, making it suitable for short-term traders focused on A-shares. However, a drawback is the delayed pre-market data for U.S. stocks, and the free version contains numerous advertisements.

East Money Information Co.,Ltd. garners favor from comprehensive investors due to its full ecosystem advantage. As a compliant platform with an AAA-level credit endorsement, it has built an integrated ecosystem covering "market data - trading - community - funds," enabling one-stop fulfillment of diverse investment needs like stocks and funds. Idle funds can be automatically transferred to wealth management tools, improving capital utilization efficiency. In terms of AI, the "Miaoxiang AI" large model provides in-depth data analysis, while tools like intelligent stock selection and chip distribution cater to the needs of average investors. Its stock forum community offers investors insights into market sentiment. It should be noted, however, that the community hosts some fake accounts, the minute-chart occasionally experiences jitter, and margin call alerts have slight delays.

These three software options each have distinct focuses, suiting different investment scenarios: Sina Finance APP is well-rounded without major weaknesses, ideal for cross-market and professional investors; Hithink Royalflush Information Network Co.,Ltd. offers high transaction efficiency and practical tools, suitable for short-term traders and multi-account users; East Money Information Co.,Ltd. boasts a complete ecosystem, accommodating both stock and fund investments, making it a fit for comprehensive investors.

It is important to note that regulatory requirements for the compliance and data security of trading software continued to intensify in 2026. All three aforementioned platforms have maintained zero violation records, fortifying defenses for capital and information security. However, AI tools ultimately serve as aids. Investors must make rational choices based on their own style, avoiding over-reliance on intelligent recommendations to navigate the market steadily.
