I’ve deployed quite a few exchange projects for clients before, and honestly, this type of system has its complexities, especially the overseas version where you need to consider multilingual support, K-line control, and contract mechanisms. Last month I helped a client with overseas projects set up a complete exchange system using this new UI version, and the experience was really good. Today I’m sharing the complete process, including pitfalls I encountered and customization options.

Complete Guide to New UI Overseas Exchange System with Perpetual & Delivery Contracts

To be honest, when I first received this requirement, the client specifically asked for perpetual contracts and delivery contracts support, plus K-line control capability. I was initially worried whether this system could handle it well, but after deployment and running for a while, the stability exceeded expectations. Today I’ll walk through the entire process from scratch, including pitfalls and customization options, all practical experience.

I. Core System Features

This overseas exchange system uses a brand new UI design, with both frontend and backend based on VUE framework, and JAVA fully open source on the server side. Deployment is much more flexible than those closed-source systems on the market, and secondary development later is convenient without being controlled by others.

The system supports very comprehensive trading modes, covering mainstream cryptocurrency trading scenarios. Both perpetual contracts and delivery contracts have complete frontend and backend support, and K-line data can be adjusted on demand. Staking finance, mining pools, and lending functions are all in the same system, without needing additional third-party integration.

Frontend Features

Mobile adaptation is well done, working on both phones and computers. Plus, the frontend directly supports black and white theme switching, making it more comfortable for overseas users. Multilingual support is standard, with English interface available by default without additional development.

Contract Trading Module

For perpetual contracts, it supports two-way trading, adjustable leverage multiples, and forced liquidation mechanism. Delivery contracts can be individually controlled for single users or single positions, which is very practical at the operational level. K-line data can be raised and controlled, suitable for operators who need to manipulate the market.

II. Pre-Setup Preparation

Before formal deployment, there are several key aspects to confirm, otherwise it will be troublesome later.

Server Environment Requirements

The JAVA server side has certain requirements for server performance, with CPU no less than 8 cores and RAM 16GB or above recommended. Database can use MySQL 5.7 or 8.0, with SSD hard drive necessary, as IO performance directly affects contract order processing speed. Frontend VUE requires Node.js environment, version 16 or above recommended.

Domain and SSL Configuration

HTTPS is mandatory for overseas business. Certificates recommended: Let’s Encrypt free certificates or paid certificates from Alibaba Cloud/Tencent Cloud. Domain names should be prepared in advance, English domains recommended for easier overseas user access.

Third-Party Service Integration

This system needs to integrate some basic services: market data sources, SMS channels, email services, and payment channels. For overseas projects, payment channels should be investigated in advance, as cross-border fund flow involves compliance issues that need priority consideration.

III. Common Issues and Pitfalls

K-Line Data Not Displaying

This is the most common issue, ninety percent of the time it’s because the backend JAVA service didn’t start properly or market interface configuration has problems. Check method: first look at JAVA logs for errors, then confirm if websocket connection is normal, finally check if market data interface return format is correct.

High Contract Order Latency

High latency generally has two reasons: unstable server network or unoptimized database queries. Recommended to add indexes to order-related tables, and check server-to-market data source network latency. During deployment, it is recommended to choose servers near the user group, Singapore servers for Southeast Asian users, US servers for European and American users.

Multilingual Switching Fails

Frontend VUE multilingual configuration is in the locales directory, with each language having its own JSON file. If switching doesn’t take effect after changes, it’s probably due to language pack loading sequence problems or some key values not being translated.

Important Note: Overseas exchange systems involve financial business. Before deployment, be sure to confirm the laws and regulations requirements of the target country. Some countries have clear licensing requirements for cryptocurrency exchanges. It is recommended to fully understand before launching operations.

IV. Customization Options

The standard version features are already quite comprehensive, but each project’s actual situation is different, so there will always be some customization requirements. Here are several common customization directions for reference.

UI Customization

If you need completely custom brand style, you can modify the style files in VUE source code. Theme colors can be changed by modifying a few variables in assets/theme.scss, without touching business code.

Trading Pair Customization

Adding new trading pairs requires configuring currency pair information in the backend, including trading precision, fee rates, leverage limits and other parameters. Before launching new tokens, it is recommended to run in test environment for a few days first, and switch to production environment only after confirming no issues.

Risk Control Module Customization

If the standard version’s position control and forced liquidation mechanism cannot meet business needs, secondary development can be done based on JAVA source code. Risk control logic is in the service layer’s RiskControlService. Be sure to fully verify in test environment before making changes.

FAQ

Q1: How many languages does the system support?

Currently supports English, Chinese, Vietnamese, and Thai four languages by default. If more languages are needed, you can expand the language pack in the locales directory. The format is standard i18n JSON format.

Q2: What is the maximum leverage for contract trading?

Default maximum is 100x leverage, but this parameter can be freely configured in the backend. It is recommended to adjust according to target market regulatory requirements, as some regions have upper limits on leverage multiples.

Q3: How is system stability?

Among the several projects we’ve deployed, the one with the largest daily trading volume ran thousands of contract orders without any downtime. Of course, this requires server configuration to keep up and database optimization to be done well.

Q4: What is the data storage solution?

Orders and K-line data are stored in MySQL, with Redis used for caching. User sessions and real-time market data go through memory, resulting in faster response speeds.

Q5: How to ensure K-line data accuracy?

The system has built-in data verification mechanism, which can cross-verify from multiple market sources. If an abnormal data source is detected, the system will automatically switch to the backup source, ensuring continuous market data integrity.
