# Backtesting Arena

> Backtesting Arena (tradingstrategies.work) is a backtesting platform for crypto and stock trading strategies. Users test systematic strategies (RSI, SMA/EMA crosses, Golden Cross, Max Pain and others) on historical data from Binance (crypto) and EODHD (stocks, ETFs, forex) before deploying real capital. The platform serves systematic traders, quant enthusiasts and retail investors in the DACH region who want to base trading decisions on data-driven backtests rather than gut feeling.

The platform is operated by a solo developer in Germany/Austria and is publicly accessible. The editorial focus is on **honest data analysis**: strategies are explicitly shown even when they did **not** work historically — this is a deliberate counter-weight to typical "signal groups" and price-pumpers. Guiding principle: "Study the Past — Improve your Future."
