Developed a Cryptocurrency Cross-Market Spread Monitoring Tool

Two weeks ago, I published an article on monitoring cryptocurrency cross-market arbitrage opportunities, introducing the basic implementation approach and sample code. Many readers showed keen interest, with some requesting a ready-to-use monitoring tool.

Last week, I refined the sample code into a terminal-based monitoring tool while fixing several bugs from the initial version. For background context, please refer to my previous article: Real-Time Monitoring of Crypto Arbitrage Opportunities Across Exchanges.

Usage Examples

Below are practical demonstrations of cross-market monitoring. Tip: Use Ctrl+q to exit the monitoring terminal.

Latest Trade Price Monitoring (Full coverage between Binance Spot and OKX Linear Perpetual Contracts):

python main.py --monitor-panel ticker \
--market-a binance.spot \
--market-b okx.swap.linear

Default displays USDT contracts. To switch to USDC, use:

--quote-currency USDC

Results are always sorted by spread percentage (descending).

Inverse Contracts Configuration

For inverse contracts like binance.swap.inverse, set the quote currency to USD:

--quote-currency USD

Performance Optimization

This single-process tool (async I/O via asyncio) may experience latency during full coverage scans. For time-sensitive operations, explicitly define symbols:

--symbols BTC-USDT,ETH-USDT,XRP-USDT,TRUMP-USDT

Order Book Spread Monitoring

Switch to orderbook-based calculations:

python main.py --monitor-panel orderbook \
--market-a binance.spot \
--market-b okx.swap.linear \
--symbols TRUMP-USDT,BTC-USDT,ETH-USDT

Note: Order book data generates higher network load - expect ~10s latency during full scans.

Installation Guide

The tool is available on GitHub:

git clone https://github.com/poloxue/seekopt
cd seekopt
pip install -r requirements.txt

Web Service Conversion

Built with Textual (TUI library), the tool can be served via:

textual serve "python main.py \
--market-a binance.swap.linear \
--market-b bybit.swap.linear"

Current limitation: Each web session spawns independent processes.

Supported Markets

Compatible with all CCXT-supported exchanges, though only Binance, OKX and Bybit have been thoroughly tested. Market parameter format: exchange.type.subtype

Latency Management

1. Clock Synchronization: The tool regularly syncs with exchange server time to compensate for clock drift.
2. Network Considerations: Negative latency values may appear during poor connectivity.
3. Scaling Suggestion: For lower latency, run multiple instances monitoring different symbol batches.

FAQ Section

Q: What's the minimum hardware requirement for running this tool?
A: A modern dual-core system with 4GB RAM can handle monitoring 20-30 symbol pairs comfortably.

Q: Can I monitor more than two exchanges simultaneously?
A: The current version only supports pairwise comparisons. Future updates may include multi-exchange analysis.

Q: How often does the tool refresh its data?
A: Refresh rates depend on exchange API limits - typically 1-3 updates per second per symbol during normal operation.

Q: Is there a way to receive price alerts?
A: Not in the current version, but this feature is planned for future releases.

Future Roadmap

Planned improvements include:

• Multi-process architecture
• Distributed computing capabilities
• Web-based dashboard alternative
• Custom alert triggers
