# BigBeluga - Backtester
***
**BigBeluga – Backtester** is a comprehensive backtesting framework that unifies the [**Market Waves Toolkit**](https://docs.bigbeluga.com/toolkits/market-waves-pro-tm), [**Market Core Toolkit**](https://docs.bigbeluga.com/toolkits/market-core-pro-tm), and [**Nautilus**](https://docs.bigbeluga.com/oscillators/nautilus-tm) into a single adaptive environment.
\
It enables traders to simulate and refine a wide range of trading strategies — from **Smart Money Concepts (SMC)** to **trend-following**, **mean-reversion**, and **momentum-based systems** — using real market structure and historical data.
By integrating advanced market-wave detection, structural analysis, liquidity modeling, and oscillator dynamics, the **BigBeluga Backtester** delivers a complete, modular testing ecosystem.
Traders can combine multiple signal layers — including trend signals, order blocks, fair value gaps, SFPs, divergences, and flow-based retests — to design complex confluence logic with full control over entry, exit, and risk-management behavior.
***
This backtesting engine transforms any trading concept into a **data-driven model**, allowing users to validate ideas, measure performance, and optimize strategy parameters with institutional-grade precision and execution consistency.
