Project Background

Recently developed an overseas exchange system for a client who required support for perpetual contracts, delivery contracts, K-line control and other features. The tech stack is Vue + Java, and I am documenting the development process here.

Exchange Mobile Interface

Exchange Mobile Interface 2

Technical Solution

  • Frontend: Vue 3 + Vue 2 (Dual Version)
  • Backend: Java Spring Boot
  • Database: MySQL + Redis

Vue was chosen for its excellent ecosystem and rich component library, making it ideal for complex exchange interfaces.

Core Features

1. Contract Trading Types

This system supports three types of contract trading:

  1. Perpetual Contracts: No expiration date, can be held indefinitely
  2. Delivery Contracts: Have expiration dates and are settled upon expiry
  3. Spot Trading: Buying and selling digital currencies

2. K-Line Control

This is an essential feature for overseas exchanges. Sometimes manual intervention of K-line trends is needed, such as pumping or dumping.

Implementation approach:

  • Store preset K-line data in the database
  • API returns preset data instead of real exchange data

3. Staking & Wealth Management

Supports earning interest by holding coins, a standard feature for exchanges.

Risk Control Measures

Exchange system risk control is the top priority:

  1. Position Limits: Single user total position cannot exceed a certain amount
  2. Withdrawal Limits: Daily withdrawal count and amount restrictions
  3. Anomaly Detection: Large frequent operations trigger risk control
  4. Liquidation Handling: Force liquidation when losses exceed margin

UI Design

Exchange UI should be professional, referencing mainstream exchanges like Binance and Huobi. Dark color schemes look professional and are eye-friendly.

Summary

Exchange system development challenges mainly include:

  1. Performance: High-frequency trading demands high performance
  2. Risk Control: Various edge cases need proper handling
  3. Fund Security: Involves real money, security cannot be overstated
