# How to Compare Exchange Prices with Copilot

Copilot fetches multi-exchange prices and helps you build arbitrage detection tools. Generate comparison data structures, create spread calculation functions, and build alert logic triggering when price gaps exceed configurable thresholds -- developing your cross-exchange monitoring application with real market data.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Get BTC prices from multiple exchanges and compare them"
3. Copilot returns prices with spread calculations
4. Ask: "Build an arbitrage monitor that checks these spreads every minute"

## Example Prompt

```
Fetch ETH prices from different exchanges so I can build a price comparison widget.
```

## Tips

- Use the multi-exchange data to build arbitrage detection algorithms
- Copilot can generate alert logic when spreads exceed a threshold
- Great for building exchange comparison features in trading apps
