Thanos

The project

Thanos is a complete environment for prototyping, testing and comparing trading strategies across several exchanges and timeframes. The goal isn't to trade: it's to have an honest test bed for the question "would this idea have worked, and at what cost in risk".

Strategies implemented

They all share the same interface, which makes it possible to evaluate them on identical ground — same data, same fees, same metrics.

Modules

• Data Manager — fetching and caching historical series per exchange and timeframe
• Custom Indicators — technical indicators implemented by hand rather than imported
• Backtest Analysis — performance and risk metrics
• Plot Analysis — visualising entries, exits and equity curves

The real lesson

The hard part of a backtest isn't making it run: it's stopping it from lying. Biases slip in easily — using data that wasn't yet available at decision time, ignoring fees and slippage, or tuning parameters on the same period used to validate the strategy.

A strategy that posts a spectacular backtest result is almost always the sign of a data leak somewhere, not of a discovery.
