Welcome. Come in and take a look around.
I'm Zhendong. I spent years building trading systems, and along the way I made tools for the things that got in my way, and for the things I wanted to do. They live here now, for anyone who finds them useful.
On the bench
MTS
The HFT trading and research system I've run since 2018, and the toolbox that checks it.Feed handlers, order gateways and drop copies for 28 venues across five asset classes, simulators to run them against, and a live demo you can watch.
Memory
The memory and journal my AI tools share, fast and local.One local memory and research journal for every assistant on your machine. What one session learns, the next remembers. Open source.
Palmtop pre-release
Build and share apps on your phone, using a few sentences.Describe an app and it gets built. Use it, improve it, or share it with others through Palmtop's own Circles or any social network or messaging app.
Desk pre-release
Desktop tools, each built for my own need.Reader, a nice document viewer for your workspace. Resume Writer, AI-supported but in your control. Docs, an AI companion to Google Docs. In your browser, or on your computer with the hub.
