About

Built by a structural engineer who has spent his career working with numbers, systems, and risk analysis. When he started investing, he found most portfolio tools were too complex and difficult to navigate - built by finance people for finance people, or by developers who do not understand what a real, regular investing person actually needs.

He built this tool because he wanted something different. A tool that treats portfolio backtesting like what it is: a way to understand your decisions, not a way to predict the future.

This is not a Monte Carlo simulator. It does not lead with complexity or mathematical risk prediction precision. It is a straightforward tool that lets you test your strategy against historical data, see what would have happened, and learn from it, fast.

He built it for people who value simplicity and clarity, backed by real numbers. People who want to understand their investments without needing a PhD in quantitative finance.

The five year testing period is free because simple financial tools should not require a subscription. Longer term projections are only valuable when coupled with great discipline and dedication.

If it helps you make better decisions, that is enough. If you value longer prediction periods and would like to stay in the game for the long run, consider supporting this application.
