After releasing the open-source historical trading data record platform for WeiShen, I received some suggestions from traders asking if it could support data from other exchanges. The main reason is that many mainstream exchanges' apps or web platforms can't display historical trading records from too long ago. For those who want to fully review their trades, document their TradeJourney, and identify blind spots in their trading, this can be quite challenging. If there were a platform that could integrate trading records from all exchanges and conduct systematic analysis, it would be incredibly helpful. So, I spent two days restructuring and upgrading the original platform, which previously only recorded WeiShen's (BitMEX) data, and officially named it **TradeVoyage**! ### TradeVoyage Major Update • **Multi-Exchange Support**: Now supports historical trading data dashboards for BitMEX, Binance Futures, OKX, and Bybit. • **Read-Only API Integration**: You can now securely download your historical trading data directly on the platform using read-only APIs—no need to run scripts to download separately. Automatic update functionality will be supported in the future. • **AI Trading Analysis**: Integrated the latest AI models (including GPT-5.2, Claude Sonnet 4, Gemini 3 Pro, etc.) to analyze past trading records from multiple dimensions. You can also design custom prompts for personalized analysis (gotta say, GPT-5.2’s analysis is pretty solid…). • **Comprehensive Optimization**: More precise position and PnL calculations tailored to different exchanges, improved candlestick charts, and trade marker displays. You can now click on a specific position to quickly jump to that time period for reviewing entry and exit logic. **TraderVoyage** is completely free and open-source! While there’s TraderSync on the market, it’s a paid tool. I hope to create a product that better meets the needs of crypto traders through a free and open-source approach. I’ll continue optimizing and updating it in the future, and I hope everyone can provide valuable feedback and feature suggestions so we can build **TraderVoyage** into the best free open-source trade review tool . The platform is fully open-source on GitHub. Since it’s open-source and self-deployed, everything stays on your own computer, so there’s no need to worry about API or data leaks.
