SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Build production-grade backtesting systems that accurately evaluate trading strategies by mitigating look-ahead bias, survivorship bias, and transaction costs.

Core Features & Use Cases

  • Bias-aware backtesting architecture that enforces point-in-time data handling and realistic cost models.
  • Walk-forward analysis and pattern-based backtester implementations for deterministic results.
  • Use Case: Validate a new trading strategy before deployment with transparent performance metrics.

Quick Start

Run a backtest on your historical OHLCV dataset using the framework to generate an equity curve and performance metrics.

FAQPage Schema
How do I prevent look-ahead bias in trading strategy backtesting?▼

To prevent look-ahead bias in backtesting, you must enforce strict point-in-time data handling. This framework mitigates such biases by time-aligning historical data and applying modular execution models to ensure deterministic results.

What is walk-forward analysis and how does it validate trading strategies?▼

Walk-forward analysis is an out-of-sample testing method that validates trading strategies across historical data. It applies modular components to evaluate strategy performance dynamically, ensuring your equity curve reflects realistic market conditions.

How do I include transaction costs when measuring strategy performance?▼

To include transaction costs when measuring strategy performance, this framework applies realistic cost models during execution. It accurately evaluates strategies by combining these costs with bias-aware architecture to generate transparent performance metrics.

Does this backtesting framework handle survivorship bias in historical data?▼

Yes, this backtesting framework handles survivorship bias in historical data. It enforces bias-aware architecture to mitigate survivorship bias alongside look-ahead bias, ensuring reliable results for comparing trading strategies.

How do I run a backtest on historical OHLCV data?▼

To run a backtest on historical OHLCV data, apply the framework to generate an equity curve and performance metrics. It uses pattern-based backtester implementations to provide deterministic results for your dataset.

What are the limitations of pattern-based backtester implementations?▼

Pattern-based backtester implementations rely on explicit time-aligned data and out-of-sample testing to function correctly. Limitations arise if your historical data lacks point-in-time accuracy or if execution models fail to account for realistic transaction costs.
