CapNav MetaTrader Signal Copier

Hybrid trading solution that parses signals from Telegram and executes them on MetaTrader (MT4/MT5) using FXBlue infrastructure. Zero-VPS web-based setup with intuitive dashboard for trade management and basic affiliate tracking.

Built a complete signal processing pipeline: Telegram bot monitors channels for trade signals, parses them using regex patterns, validates against risk parameters, and executes via FXBlue's REST API.

How I Work

I don't do discovery calls or elaborate proposals. You tell me what you need, I tell you if I can build it and how much it costs. If we agree, I start immediately.

Step 1

Email me your requirements

Describe your strategy, what platforms you're targeting, and what success looks like. The more specific you are, the better. I'll respond within 24 hours with whether I can build it, timeline estimate, and fixed price.

Step 2

Build and deliver

Once we agree on scope and price, I start building immediately. You get regular updates and can review progress. I deliver the working system with documentation and source code, provide support during initial deployment, and fix any bugs.
