In productionTrinity
A trading system that runs on our own capital.
Trinity is NSi4's high-frequency arbitrage system. It trades the studio's own money around the clock, so every engineering decision in it has a price.
01 Problem
In arbitrage, a late decision is a loss.
An arbitrage window opens when the same asset is priced differently in two places, and it closes as soon as someone else acts on it. A system that decides slowly, or decides wrongly, pays for it in real money.
02 Constraints
No client funds, no maintenance window.
- Capital
- NSi4's own money, never a client's
- Hours
- 24/7/365; the market sets no maintenance window
- Risk
- Risk checks run before every order, not after
- Audit
- Every decision recorded with full telemetry
03 What We Built
An arbitrage system built risk-first.
Three parts, each with one job: act inside the window, stop any order that breaks a limit, record every decision.
Execution
High-frequency arbitrage that acts on a price difference before the window closes.
Risk controls
Every order passes its risk checks before it leaves the system.
Telemetry
Every decision is recorded, so any trade can be traced and reviewed.
