A must-read for quantitative traders: Use API to access permanent commission rebates and let your robots earn money!

Brothers, the quantitative veterans have gathered! Doesn’t it hurt every time you see the high-frequency trading fee bill? It’s too troublesome to do rebates manually, and you can’t keep up with the pace of robots, right?

Today, we are not going to fix it, but directly give some guidance to quantitative teams and programmatic traders with development capabilities - how to use exchange APIs to get permanent fee discounts for your robot trading! ** This is no small matter, the savings are real money.

Why does quantitative trading require rebates?

Anyone who plays quantitatively knows that the break-even point of a strategy is often stuck at that fee. Whether it is market making, arbitrage or high-frequency trend following, the cost of each transaction will be infinitely magnified. **Getting a permanent and stable commission rebate is equivalent to directly lowering your transaction costs, and the overall profit margin of the strategy is immediately opened up. ** This is not a small amount of money. It will definitely be a considerable amount of income if accumulated over time.

Core reminder: Be sure to use regular and safe channels to obtain API keys and rebate qualifications. Don't touch those "pheasant" agents or codes with unknown origins. Be careful of API keys being leaked, and your assets will be reduced to zero overnight!

How to bind rebate to your quantitative account?

Below, I’ll take the world’s two major exchanges—Binance and OKX—as examples to give you a clear idea of access. Note, The following process must be based on an account registered through official formal rebate channels (such as CoinRebate), so as to ensure that you enjoy the highest level of rebate discounts from the source.

Prerequisite: First get an exchange account with rebates

This is the most critical step! If your exchange account is registered directly without any referral code, then sorry, your trading will basically not be eligible for rebates. **The correct approach is to use the highest authority permanent rebate referral code directly when creating an exchange account. **

Binance users: Be sure to register through this link, fill in the referral code LULALA, and directly get 20% handling fee discount.

OKX users: Be sure to register through this link and fill in the referral code LULALA to also enjoy the 20% handling fee discount.

**Only accounts registered using the above method and subsequent transactions through the API are eligible for rebates. **

Core steps: Add the rebate tag (Tag) to the API call

After getting an account with rebate qualifications, the next step is to tell the exchange: "This transaction initiated through the API is my fault!"

Create and manage API keys: Go to your Binance or OKX account backend and create an API Key securely (it is recommended to only enable trading permissions and turn off withdrawal permissions to prevent one-handed manipulation).
Get your exclusive rebate identification code: This code (usually called tag, source or referralCode) must be obtained from your rebate service provider (such as CoinRebate). **It is tied to the commission rebate of your account. **
Change your trading program: When calling the exchange’s order interface, remember to insert this rebate identification code into the request parameters of your program.

For OKX API: You have to fill in the unique value we gave you in the tag field of the order request. In this way, the exchange can identify that the transaction comes from your quantitative account and accurately credit the commission rebate to you.
For Binance API: Binance’s spot trading API rebate binding logic may be a little different, and usually relies more on the recommendation relationship of the account itself. But to be on the safe side, it is recommended to add a specific prefix to fields such as newClientOrderId in the program, or read the official documentation in detail and ask your rebate service provider.

Important documents and follow-up actions

OKX API official documentation: This is the authoritative information you must read when developing. Take a closer look at the description of the interface call and tag field. Go to OKX API documentation
Binance API Official Documentation: Again, all parameters and rules are subject to the official documentation. Go to Binance API documentation

After completing the above settings, your programmatic transactions will automatically enjoy commission rebates. You can regularly check the income status in the exchange's rebate records or in the backend of your rebate service provider.

A few words of truth to the quantitative team

Security first: Take good care of your API keys, use security measures such as IP whitelisting and regular key changes to prevent hackers from taking advantage of the loopholes.
Regular channels: For rebates, you must find a long-term and stable platform like CoinRebate that provides the highest discounts from formal exchanges. Don't let the rebate settlement go wrong because of unstable agency channels.
Ask proactively: The API rebate policies of different exchanges and different product lines (spot, contract) may be slightly different. If you get stuck during the access process, the most effective way is to contact your rebate service provider for dedicated support.

I hope this guide can help you open up the "Ren and Du" of quantitative trading to save money. The transaction has become so complicated. If you can save a little on handling fees, keep this part of the profit firmly in your own hands!

**Don’t hesitate, quickly use an account with permanent rebates to start your quantitative journey! **
