why main sequence

Main Sequence Is a Data Driven Platform

Whether the outcome is a new prediction, a risk factor, model signals, a presentation, or a dashboard, every result begins with collecting, transforming, and delivering data—and at Main Sequence, that orchestration isn’t an afterthought, it’s the core of our platform. By mastering, unifying, and scaling data workflows through the Main Sequence Data Engine, we give enterprises the foundation for both efficient financial operations and true artificial intelligence.

Step 1

Define a Data Node

Define a process by simply creating a class. Each node is uniquely identified by hashing its code and configuration, and it automatically links to the Data Engine for persistence.

class RawTrades(DataNode):
def update(self): ...

Step 2

Build your Data Graph

Construct complex workflows by simply declaring dependencies. The system automatically builds the graph structure, ensuring inputs flow correctly to outputs in the Compute Engine.

def dependencies(self):
return ["RawTrades"]

Step 3

Deep Logic & Workflows

Orchestrate deep dependency chains. AlphaSignal recalculates automatically whenever VolumeBasedBars or Volatility updates, maintaining data integrity.

return ["VolumeBasedBars", "Volatility"]

Artificial Intelligence

Interact with natural language

The Main Sequence SDK, combined with the platform’s unified framework, allows any function or method to be automatically exposed as an agentic tool — with no extra setup or maintenance.
Because workflows, data, and infrastructure are abstracted and standardized, LLM-assisted agents can execute complex operations or surface insights to business users in seconds.

Risk becomes a real-time engine, delivering live risk insights directly to trading and portfolio management.

Equity Research

An equity research team transformed scattered Excel spreadsheet insights into a centralized source of knowledge

Custom metrics, results, and analyses are now accessible through a unified API, and the clear separation between metrics and analytics has significantly improved the maintainability of their models. This shift opened the door to deeper insights and greater coverage at scale.

Investor Solutions

An investor solutions quantitative team transformed all their calculators and pricing models into institutional-grade dashboards and LLM-powered assistants for their sales force.
