Built for different kinds of work
Fast requests, live updates, and heavy calculations each have a home.
Some work needs an answer right away, some runs around the clock, and some needs serious computing power. TradingSDK gives each its own place, so heavy work doesn't slow down the app people are using.
Ongoing tasks
Background services
Data imports, alerts, indicators, and scheduled work continue without slowing down the app.
Trading and research
Engine
Dedicated processing handles live trading, simulated trading, backtests, and optimization.
Realtime updates
Live delivery
Prices, trades, and portfolio changes reach connected apps as soon as they happen.

What happens to an order
Every order follows a clear, controlled path.
From the moment someone taps Buy or Sell, the order is checked, routed to the right place, recorded, and reflected in their portfolio.

Every step has a clear owner. Orders are checked before anything changes, and money movements are recorded in the same step, so nothing is ever left half-recorded.
How it is engineered
Built with the discipline trading software demands.
Our standards aren't just written down. Tests and compiler rules check them automatically, and every service has its own design document.
415
Architecture rule tests
Automated checks make sure every service follows the rules for dependencies, naming, security, and accounting.
20
Custom code-analyzer rules
Our coding rules are built into the compiler, and warnings that have been fixed can't creep back in.
12,000+
Automated tests
Spread across 160 test projects, including tools that simulate failures and replay past market data.
670K+
Lines of C# code
Not counting comments or blank lines. On top of that, 156,000 lines of documentation sit right alongside the code.
137
Documentation pages
334,000 words covering service designs, coding standards, and operations guides.
46
Service design documents
One for every service, describing what it does, the actions it supports, and the business rules it follows.
