Finance Strategy Backtester

Most traders test strategies with gut feel or cherry-picked charts. This backtesting platform changes that. It lets you define entry and exit conditions, run them against years of historical price data, and then layer ML models on top to surface hidden patterns, regime shifts, and the conditions under which each strategy actually performs. Built in Python with a clean analytical interface, it's the difference between thinking your strategy works and knowing it does.

Problem and Solution

The Problem

Retail and semi-professional traders have no rigorous way to validate their strategies before deploying real capital. Backtesting tools that exist are either too simplistic (ignoring slippage, fees, and regime changes) or too complex for non-quants. Worse, most don't explain *why* a strategy worked — just that it did, in the past.

Our Solution

A backtesting engine that simulates realistic trade execution with configurable slippage, commission, and position sizing — then runs ML models to identify which market conditions favoured each strategy. Feature importance analysis shows which indicators actually drove returns. Rolling performance windows reveal whether a strategy is robust or just overfit to a specific bull run.
