When you're managing multiple positions and expiration dates simultaneously, it's easy to lose track of the real picture. Early in my trading career I got a margin call — not because the market moved against me, but because my mental model of my leverage and open positions was simply wrong. That's why sTraderZ.com exists: a tool that shows me exactly where I stand, instantly.

📈 For Traders 💻 By a Developer 🎯 From Real Need
Three reasons why sTraderZ.com was built
🚨
Never a margin call from a calculation error again
All positions, all risks, one glance — sTraderZ.com shows you exactly where you stand before your broker does.
💸
No monthly fee for a trade log
A professional journal doesn't need a subscription. It belongs to the trader — fully, with no lock-in.
Time-intensive strategies need signals, not manual monitoring
The signal engine turns hours of manual monitoring into a single notification.
How the tool grew

sTraderZ.com has been running in my own daily trading for months — I was the sole user, tester, and developer all at once. Every feature was built because I needed it myself.

During the closed beta, community testers contributed further ideas that were implemented directly. Today the platform includes 110+ service classes, broker integrations, full options strategy recognition, and a tax reporting module for 19 languages.

The guiding principle remains: everything I wish for as a trader, I build in step by step.

⌨️ 30+ years of code & entrepreneurship 🏛️ Foundation founder 🎓 Graduate in business information systems 📜 PMP · Scrum Master · Product Owner 🏢 Projects for Siemens, Mercedes-Benz, Infineon & co.

sTraderZ.com is not an anonymous startup or a venture-capital project. The platform is run by the owner-operated Matthias Sax GmbH, based in Fürth, Germany — with a clear imprint, a reachable contact, and a founder who trades himself.

Matthias Sax has been an entrepreneur, technologist — and above all a developer — for over three decades. He wrote his first code at the age of 14, and building software has never let go of him since. Curiosity became a craft — and the craft became a company.

📈 From the Commodore C64 to a trading platform
1990 Learned to program at age 14 at summer camp — BASIC and assembly on the Amiga.
1991 Ran his own bulletin board system, "El Dorado BBS", at age 15 — including a Usenet uplink, long before the internet became part of everyday life.
1997 Ran his own internet point of presence on SuSE Linux — with a leased ISDN line and six dial-in numbers.
1999 First client project in his early twenties: a B2B online shop. The start of his commercial software development.
2001–2014 His own internet platforms for students (including pruefungsgeil.de) — self-built and scaled to up to 4 million visits per month: MySQL cluster, weighted search, ranking #1 on Google.
2004–2006 Advised the United Nations (CEPAL) and the government of Chile on open-source software in the public sector — officially published by the UN (thesis graded 1.0, top mark).
2005 → Over 20 years of IT and digitalization projects as a project lead and systems architect — for companies such as Siemens, Mercedes-Benz, Infineon, DATEV, Trumpf, Leonhard Kurz, medi and UVEX. Certified Project Management Professional (PMP), Scrum Master and Product Owner.

⚖️

Matthias is also the founder of his own family foundation and has organized and co-hosted a tax seminar together with tax advisor Daniel Diemar.

🎯

And above all: Matthias is an active options trader himself and the organizer of an options trading camp. sTraderZ.com grew out of his own need — built by a trader for traders, not on the drawing board of a marketing department.

On his YouTube channel, Daniel Diemar covers various tax strategies. On the topic of stock trading, he has created a four-part video series. He is available for bookings via his contact details published on YouTube.
