Skip to main content
The Symphony Quantitative Vector (SQV) owns reusable framework contracts for quantitative research, trading-system construction, execution support, and later quantitative engines. Strategy logic always belongs to you. SQV supplies framework surfaces and exact compatibility evidence, but it never determines your instruments, feeds, subscriptions, order logic, or execution model.

​
User strategy boundary

You retain complete ownership of strategy logic. SQV does not:
  • Select your instruments or data feeds
  • Define subscription fields or market depth
  • Determine failure behavior or normalization rules
  • Write order logic or execution models
  • Design your internal modular structure
Symphony gives compatibility evidence and supported operations. It never ranks strategies or imposes platform law on your trading decisions.

​
SOOV: Symphony Orchestra Omega Vector

SOOV is the first named subvector under SQV. It represents a future high-performance, C++-only FIX architecture informed by historic QuanuX work. SOOV is planned as a bounded, deterministic messaging layer for trading communication. Detailed FIX behavior is not yet canonical; no FIX session, feed adapter, or broker integration is currently implemented.

​
Future scope

SQV is the planned home for ratified quantitative framework components across later delivery phases. Expected areas include:
  • Backtesting engines
  • Broker C++ APIs
  • Indicator libraries
  • Quantitative mathematics
  • Data-stream architecture
None of these are implemented until their respective contracts are ratified.

​
Current status

SQV is a canonical architecture contract only. No SQV or SOOV engine, FIX session, feed adapter, strategy runtime, broker integration, backtester, indicator library, or data-stream component is currently implemented.

​
How SQV relates to other vectors

SHV

Supplies hardware capability evidence that constrains quantitative engine design.

SNV

Records the Nodes where quantitative workloads execute.

SKV

Governs SQV contracts, evolution, and official publication relationships.
