OptionIncome

OptionIncome is a powerful SaaS platform designed to revolutionize how options traders track and analyze their strategies. It automatically syncs with your broker to provide a comprehensive journal and real-time tracker, moving beyond individual trades to show the true profitability of complex options strategies like covered calls, spreads, and the wheel. This essential tool targets serious options income traders and investors who want to manage their portfolio like a business, gaining deep insights into their performance and optimizing their trading decisions. Key Features Automatic Broker Sync: Connects once to major brokers (Robinhood, Schwab, Fidelity, E-Trade, Tastytrade, Webull, IBKR, Moomoo coming soon) for seamless import of full history and live positions. Strategy-Based P&L: Links individual trades into cohesive strategies, providing true running profit and loss for rolls, spreads, and multi-leg positions. True Cost Basis for Wheel Strategy: Factors in all premiums collected for cash-secured puts and covered calls to calculate an accurate adjusted cost basis. Real-time Data & Analytics: Displays live Greeks, IV, and TradingView charts for open contracts, helping identify roll candidates and profit targets. Comprehensive Trading Journal: Automatically logs all closed trades, allowing search by ticker or strategy, and revealing cumulative P&L curves. Performance Insights: Identifies which strategies are most profitable and which need adjustment, verifying consistent income generation. Use Cases OptionIncome is invaluable for traders who find their broker's statements insufficient for strategic analysis. For instance, a trader employing the wheel strategy can finally see the true adjusted cost basis across an entire cycle, from the initial cash-secured put through assignment and subsequent covered calls. This clarity helps determine the exact strike price needed for covered calls to remain profitable, even if the stock moves unfavorably. For those who frequently roll positions, OptionIncome transforms what brokers see as "realized losses" into a continuous strategy in motion, tracking the cumulative P&L from the first open to the final close. This allows for better decision-making on when and how to roll for optimal outcomes. Furthermore, the platform helps traders identify their most effective strategies by analyzing historical performance, enabling them to refine their approach and stop trading less successful methods. Pricing Information OptionIncome offers a flexible pricing structure, including a 14-day free trial with full access to all features. The Pro Plan is available for $19/month when billed annually ($228/year), offering comprehensive analytics and unlimited broker connections.

Users simply connect their broker once, and OptionIncome handles the rest, keeping live positions and trade history in sync. Support resources include detailed documentation and a changelog for common questions, ensuring users can quickly get started and maximize the platform's capabilities. Technical Details OptionIncome leverages the SnapTrade API for secure and reliable broker connectivity. This integration ensures read-only access to user accounts, with SnapTrade handling the login process to prevent credentials from being shared or visible to OptionIncome. The platform is specifically built for equity options, supporting a wide range of strategies including Cash Secured Puts, Covered Calls, various Spreads, Iron Condors, and Strangles. Pros and Cons Pros: Automated broker syncing; Strategy-level P&L tracking; Accurate adjusted cost basis for Wheel Strategy; Real-time market data and Greeks; Comprehensive, searchable trade journal; Supports major options strategies and brokers. Cons: Does not currently support options on futures or crypto; Auto-sync requires manual trigger (auto-sync "coming soon"); No explicit mention of mobile app (implies web-based only); Limited information on advanced customization options.
