The easiest way for beginners to start trading with lower fees. Enter the code once and save on every trade.
Published: March 2026An invitation code is a special text string you enter when creating a new OKX account. Code BUYSTOCK gives you a 20% discount on all trading fees — spot, futures, and margin. This is the maximum discount available through the OKX referral program.
The discount is permanent and automatic. Once registered with code BUYSTOCK, every trade you make costs 20% less in fees. There is no expiration and nothing extra to enable.
Visit okx.com/join/BUYSTOCK. This link automatically fills in the invitation code.
Enter your email or phone number and set a password. Verify that the invitation code field shows BUYSTOCK. If the field is empty, type it manually.
Complete email/phone verification, then upload a government ID for KYC. OKX verification is typically approved within minutes.
Deposit crypto or buy with local currency through OKX P2P (zero fees). Your 20% trading discount from BUYSTOCK is active immediately.
OKX is one of the most beginner-friendly exchanges available. The interface is clean, the mobile app is well-designed, and the P2P marketplace lets you buy crypto with local currency without paying any exchange fees.
Without an invitation code, OKX charges 0.08% maker and 0.10% taker for spot trading. With code BUYSTOCK, these drop to 0.064% maker and 0.08% taker. On a $1,000 trade, you pay $0.64-$0.80 instead of $0.80-$1.00.
P2P trading on OKX is completely free regardless of whether you have an invitation code. This makes OKX an excellent choice for people who need to convert local currency to crypto as a first step.
