Algorithmic Trading, Reimagined

The modular synthesis paradigm — proven over 60 years of electronic music — maps to algorithmic trading with startling precision.

Visual Strategy Builder

Drag modules from a palette. Connect them with color-coded cables by signal type. Your strategy's logic is visible at a glance — no code, no compilation, no waiting.

Real-Time Signal Probing

Click any cable to see the data flowing through it — as sparklines, numeric readouts, or gate timelines. The equivalent of an oscilloscope for your trading strategy.

Unlimited Depth

Start with 3 modules for an SMA crossover. Scale to dozens for multi-timeframe, multi-indicator strategies with dynamic position sizing and risk management.

Five Signal Types, One Coherent Language

Every connection is color-coded. Every signal type has a defined range and purpose.

Signal Trading Concept Range Example
Audio Raw market data — price, volume, order book Unbounded Price VCO, Depth Scope, VWAP
CV Normalised indicators — RSI, z-score, conviction [-1, 1] RSI Oscillator, Z-Score, Bollinger
Gate Binary states — trend direction, position on/off 0 or 1 Threshold Gate, Logic AND/OR
Trigger Discrete events — crossovers, fills, breaches Momentary Crossover Detector, Debounce
Clock Timeframe and sampling rate Regular pulse MTF Sampler, Kline Generator
