I will do a live presentation and demonstration of my current work to integrate the Quotes and Lightwing projects on December 10, 2026, at the regular meeting of the D/FW Unix User Group.
Come hear the story of a local embedded Linux developer, turned self-taught option trader’s 10 year journey doing just that!
I will explain and demonstrate how I leveraged open-source software and hardware (Yocto Linux, curl, OpenSSL, OAuth, PNG, PowerVR and OpenGL), running on ARM (like Raspberry Pis), to build the custom platform I use daily for genuine trading edge in my investments.
What began as automation scripts for Excel, became a stand-alone, touch-driven GUI that charts entire stock and option portfolios with real-time quotes and animated risk visualizations on an open-source 3D game engine.
It’s called Lightwing Quotes and it may become a commercial product someday. But right now, it’s about the journey!
The rapid rise of stock option trading has enabled many new fintech start-ups to offer increasingly powerful APIs for developers and retail investors to exploit. Even big option trading firms, like Citadel, Susquehanna and Jane Street, are increasingly returning to C++ for the custom software they develop internally for their option market making and arbitrage teams.
But, problems still abound for independent developers and retail traders. AI agents are a serious threat to open-source projects and App Stores continue to lock-down many into controlled ecosystems, dominated by an elite few. New compliance mandates for NIST’s CMVP (Cryptographic Module Validation Program) are taking over OpenSSL and even threaten the curl project.
Despite the issues, Yocto Linux continues to be one of the best tools for building new autonomous systems that are ready to deploy commercially, without requiring App Stores, advertising monetization or a resident Linux kernel guru.
The established brokerage trading platforms are powerful and beautiful, but emphasize day-trading, social networking, gaming, and AI agents to boost commission revenues for the banks. But, frequent trading is not appropriate for most investors and the new trading APIs can be exploited in much better ways, like automating the visualization of markets for better option selection and trading edge.
Lightwing Quotes continuously streams real-time market quotes and account data from multiple fintech API’s into Excel and/or custom GUIs, built for what is important to retail investors. It moves the burden of continuous charting from heavy, browser-dependent platforms to a dedicated, always-on, touch-enabled display, optimized for what retail traders actually need. Lightwing overlays portfolio positions, market order entry and status, transactions and alerts, all with just a single, daily, two-factor, authenticated login through OAuth protocols, OpenSSL and curl.
Very small development teams can still build new, competitive, commercial applications to meet new opportunities today, not dependent on AI, OS, hardware or web platforms. Come join us and see for yourself!
This talk will be at the monthly meeting of the D/FW Unix Users Group on Thursday, December 10, 2026, at 7:00 pm at the office of Improving, in Plano. This is a free event, open to the public and pizza is usually provided by Improving. Check their website for more information. I hope to see you there!
