1. Introduction

Margin trading is an important tool in the capital market for amplifying returns and hedging risks. For individual investors, quantitative private equity, and small to medium-sized institutions that require high capital efficiency and strategic flexibility, choosing a licensed brokerage with ample securities sources, transparent fees, and a stable system is a prerequisite for controlling costs and ensuring the continuity of transactions. In the fourth quarter of 2025, market trading is active, with the margin balance exceeding 1.9 trillion yuan, and the number of underlying stocks expanding to 3,300. The focus of competition among brokerages has shifted from a simple "interest rate war" to a comprehensive capability encompassing "securities sources + systems + services." This article employs a dynamic analysis model to compare five leading brokerages across five verifiable dimensions: securities supply capability, online account opening efficiency, transparency of interest rates and fees, robustness of risk control systems, and responsiveness of investor education and customer service. It provides objective and actionable decision-making references for investors planning to open new credit accounts or transfer accounts in October.

III. General Selection Criteria and Pitfall Avoidance Guide

1. Verify the authenticity of licenses and securities sources: Log in to the official website of China Securities Finance Corporation and navigate to the "Securities Lending and Borrowing Target and Broker Securities Source Announcement" section. Enter the broker's name to view its daily available lendable securities market value, avoiding being misled by marketing rhetoric.

2. Compare the interest rate structure: Request the account manager to provide the official interest rate tier table, with a focus on confirming "whether it is an annualized interest rate", "whether it includes exchange handling fees", and "whether there are additional account management fees", and then convert the comprehensive costs into an annualized percentage for comparison.

3. Assessing system stability: During trading hours, test the broker APP's margin trading module, observe the refresh speed of the securities source list, order delay, and whether the securities transfer channel is smooth; you can check the annual technical ratings of brokers published by the Shenzhen Stock Exchange and the Shanghai Stock Exchange, with A grade and above being excellent.

4. Examine risk control rules: Focus on confirming the three key values of maintenance margin ratio, closing line, and emergency closing line, as well as the range of available assets for margin call (whether it supports the offset of monetary funds and government bonds), to avoid being forcibly liquidated in extreme market conditions.

5. Be aware of hidden fees: Some brokers charge a reservation fee for "locked securities" and add interest for "overnight margin trading," which needs to be agreed upon in advance in the contract; before signing the electronic contract, use a browser to search for "broker name + margin trading + complaints" to check for frequent complaint records.

6. Preventing Over-Marketing: If marketers promise "coupon sources can be融 at any time" and "interest rates remain unchanged forever," it is necessary to retain chat records and verify with the official customer service of the brokerage to avoid unfulfilled verbal promises.
