Finmiti

This project is developed for my personal use. I am developing this to keep the documentation, architecture and pipeline consistent so that I can focus more on developing strategies instead of developing pipelines.

This project is solely developed for my personal use. I am publishing this only to keep myself updated and to remove the headache of setting up the framework again and again.

Finmiti is a research-first quantitative trading framework designed to keep strategy logic, execution logic, and accounting logic strictly separated.

It exists to eliminate repeated reinvention of trading pipelines, so you can focus on researching strategies, not rebuilding infrastructure.

What Finmiti Is (and Is Not)

Finmiti is:

• a framework for systematic trading research
• equally suited for backtesting and live trading
• opinionated by design
• built around explicit, auditable abstractions

Finmiti is not:

• a strategy library
• a signal generator
• a black-box trading system

If you want flexibility at the cost of correctness, this framework will feel restrictive. That restriction is intentional.

The Core Trading Loop

Every strategy in finmiti follows the same explicit loop:

Market Data → Strategy → Orders → Portfolio → Execution → Accounting

Each stage is implemented as a separate module with strict responsibilities.

This guarantees that:

• strategies remain stateless
• execution assumptions are explicit
• accounting is consistent
• backtests can be trusted
• live trading reuses the same abstractions

Major Modules

Finmiti is organized into the following conceptual modules:

Client Handling

Handles interaction with external systems such as broker APIs and live data feeds. Keeps the rest of the framework broker-agnostic.

Stocks

Manages symbols, historical data, and OHLCV storage. Acts as the foundation for all market data access.

Strategy

Consumes immutable market snapshots and emits order intent only. Strategies never manage cash, positions, or execution details.

Orders

Orders are the contract between strategy, portfolio, and execution. They represent intent, not outcome.

Executioners

Simulate (or connect to) market reality: slippage, brokerage, partial fills, or live execution.

Portfolio

The single source of truth for positions, cash, and PnL. All state mutation happens here.

Backtesting

Pure orchestration. Iterates over time and wires everything together without adding logic.

Final Note

I have built this for my personal use in mind.
