Hello!

I am looking for developers to create a web terminal for traders — focusing on displaying Level 2 market data, with the ability to connect to various data sources and preparing the platform for future integration with trading brokers.

The goal of the project is to build a modular, scalable trading platform that can later be provided to retail and institutional traders. In the future, the project is evolving towards a professional terminal with paid data and trading features.

Stage 1: MVP (working web application on crypto data)

Data sources:

At the first stage — cryptocurrency exchanges with free access to Level 2 data:
Required data:
- Order book (Level 2 order book) — in real-time via WebSocket
- Trade feed
- Historical data (prices, volumes)

What should be implemented in the MVP:

Terminal frontend:
- Clean and user-friendly interface for the trader
- Display of the order book, charts, and control panel
- Display of trading results: P&L and all related charts
- Components: ticker selection, indicator panel, navigation buttons
Charts and analytics:
- Display of prices, volumes, indicators
- Support for calculation and display: SMA, EMA, MACD, RSI, volumes, etc.
- Ability to add custom indicators (by formula)
Multi-ticker mode:
- Ability to switch between tickers
- Ability to display multiple charts simultaneously
Data storage and aggregation:
- Saving order book and trade history on the server or in a database
- Updating market data in real-time for the possibility of trading short sessions (1 minute, 30 seconds, etc.)

Lay the groundwork for future integration:

Connecting data from paid sources (stock market) — it is important that the architecture allows for easy addition of new feeds (NASDAQ TotalView, NYSE OpenBook, etc.)
Ability to connect to broker APIs (e.g., Alpaca, Interactive Brokers, etc.)
Extensibility: adding custom strategies, signals, alerts, and trading modules

Please include in your response:

Experience working with trading platforms, fintech, or WebSocket data
Project examples (if any) and GitHub / portfolio
Proposed tech stack
Estimated timelines for implementing the basic version of the MVP

If you have additional suggestions for improving the architecture or UX — we would be happy to discuss them!

1. Which cryptocurrency exchanges should we support first? (Binance, Coinbase Pro, – each has different API structures and rate limits)_
2. Do you already have accounts or API credentials for the exchanges we’ll use for development?
3. What’s the expected data retention duration for order books and trades?
4. Do you have any references you like in terms of UI/UX?
5. Should we support dark/light themes or any branding from the start?

Hello!
We offer you not just website setup, but a ready-made solution for growth and attracting clients.

Our main advantage is that we not only develop the website but also set up a partner (referral) program integrated into our own platform ailalab.com. This means that after the website is launched, webmasters from our network will start promoting it — you will only pay for results (attracted clients, applications, or purchases).

What you get:
1) A modern, responsive website tailored to your needs;
2) Integration with a tracking system and accounting for partner referrals;
3) Attraction of webmasters and arbitrage specialists who will promote your website for a commission;
4) A free CRM system for processing orders (if necessary);
5) Full support and consultations at all stages.

If you are looking for not just a developer, but a team that will help attract traffic and increase sales — write to us, and we will discuss the details of your project.
