Good news for quantitative traders: Can you earn commissions by placing API orders? Lao Jiucai teaches you how to save handling fees

Brothers, those who engage in quantitative trading and write their own programs to run strategies, do you always feel that transaction fees are flowing away like running water? Don’t feel bad, today I’m here to talk to you about how you can enjoy commission rebates when calling the exchange’s API to place orders, keeping costs to a minimum!

Knock on the blackboard and emphasize 10,000 times: To play with quantification and connect to APIs, the first priority is to choose a safe, formal, and in-depth large exchange. Don't try to connect to the APIs of unknown firms just to save some handling fees. When the strategy is running smoothly, the exchange runs away, and you can't even get your principal back, then that will be a real loss. We only promote the world's top, licensed and compliant platforms, which are reliable and reliable.

Core principle: Bind the rebate relationship through the recommendation code (Tag)

For programmatic traders, the core of obtaining rebates is: when you place an order through the API, bring a specific Referral Code or Tag in the request. In this way, the exchange's backend system can identify which referral channel the transaction was brought by, and return part of the handling fee to the recommender (that is, us), and we will share this part of the revenue with you.

This is the same as manually registering on the exchange’s official website or app using the referral code. The effect is the same: you will get a permanent transaction fee discount. To put it bluntly, it is to collect the wool of the exchange to make our strategy run more easily.

How to bind rebates to your quantitative account?

Below, we take two major exchanges—Binance and OKX—as examples to explain the binding ideas. **Please note that the following process is a general logic description. The specific API parameter names may change with exchange updates. Please be sure to refer to the latest official documents. **

1. Preparation: Have an account with a referral code

Before performing any API operations, you need to have an exchange account first, and this account is registered through the official recommendation link, so as to ensure that your account itself is eligible for rebates.

Important: Please be sure to register through the above formal link to ensure that the account is bound to the rebate relationship from the beginning. Do not use links from unknown sources to prevent information leakage - the currency industry is deep and safety comes first.

2. Create and configure API Keys

Log in to your Binance or OKX account, create an API Key for programmatic trading on the account settings or API management page. Usually you need:

  • Set a label for the API Key (such as MyQuantBot).
  • Keep your API Secret strictly, it is only displayed once and is equivalent to a password. If you lose it, you will be in big trouble.
  • According to your strategic needs, check the appropriate permissions (such as reading, trading, withdrawal, etc.). Follow the principle of least privilege and do not open withdrawal permissions easily to guard against black swans.

3. Embed the rebate ID (Tag/Referral Code) in the API request

This is the most critical step. When you write a program to call the exchange's order interface, you need to pass in the specified Tag in the request parameters.

Take OKX as an example: When calling OKX's POST /api/v5/trade/order and other order interfaces, consult its official API documentation, and you will find a field used to identify the agency or recommendation relationship (such as tag, a specific format of clOrdId or a separate referral parameter). You need to set the value of this field to the exclusive Tag we provide.

**Hypothetical example (please check the latest OKX API documentation for specific parameter names): **

{ 
"instId": "BTC-USDT", 
"tdMode": "cash", 
"side": "buy", 
"ordType": "market", 
"sz": "0.001", 
"tag": "YOUR_OKX_REFERRAL_TAG" // The rebate tag bound to your account should be filled in here 
}

For Binance: Binance API's order interface (such as POST /api/v3/order) usually has a similar mechanism, which may implement agent identification through a specific prefix of newClientOrderId or some combination of fields such as recvWindow. The specific implementation method is more complicated, and there may be specific policies for quantitative access. It is recommended to read more documents.

Important tips and suggestions

  1. Policy Priority: Before starting, it is strongly recommended that you directly check the instructions on "Agent", "Recommendation Program" and "API Rebate" in the exchange's official documents. Each exchange may have different policies on whether transactions generated through APIs can be enjoyed and how to enjoy referral commissions, and will be updated - don't be lazy, read the documentation first!
  • OKX API documentation: Please search in the OKX official website help center.
  • Binance API documentation: Please search in the Binance official website help center.

  1. No spot rebates: Please note that the promotion plans of some exchanges may only support rebates for contract transactions but not spot transactions (for example, Binance does not support spot rebates). This means that even if you set the tag correctly, your spot API transactions may not generate commissions. Be sure to confirm clearly before accessing, so as not to waste your time.

  2. Contact official channels: If you are a quantitative team with huge trading volume and want to engage in more in-depth cooperation and customized rebate plans, the best way is to directly find the application portal for "Agents", "Partners" or "Prime Brokerage Business" through the official website of the exchange. As a platform with 8 years of experience, we can also help you connect:

  • Binance Agent: After registering through the registration link we provide, you can apply in the account or contact us for assistance.
  • OKX Agent: You can also register through our link and apply further.

Recommendations for other exchanges that support API rebates

In addition to Binance and OKX, these mainstream exchanges also provide complete API services and potential rebate plans. Quantitative players can pay more attention and contribute more:

Summary

Quantitative trading makes money from strategies, and the handling fees saved are pure profits. Binding rebate tags in API calls in the correct way is an effective way for you to reduce long-term transaction costs. The core operation is three steps:

  1. Register through a formal referral link and obtain an account eligible for rebates.
  2. Read the official API document of the exchange carefully and find the parameters binding the recommendation relationship.
  3. Set this parameter correctly in the order request of the program.

Remember, safety always comes first. From account registration to API management, every step must be completed on the exchange’s official platform. Don’t worry about the handling fee anymore. Make good use of the recommendation code to make your quantitative strategy travel even further!
