# Noon Barbari

> Noon Barbari is a crypto strategy backtesting platform focused on honest validation: it
> replays trading strategies on real historical data, then stress-tests the result with
> walk-forward analysis, Monte Carlo simulation, and a deflated-Sharpe-based robustness score
> to detect curve-fitting (overfitting) before real money is at risk. A free, no-signup
> backtester is available at https://noonbarbari.xyz/whatif. Noon Barbari does not provide financial
> advice, trading signals, or custody of funds.

Key facts: strategies are defined as transparent rule sets (visual designer or YAML, plus
TradingView Pine Script import), backtests run on real exchange OHLCV data, and every public
result carries a robustness verdict so readers can tell a real edge from a memorized past.
A free tier exists; paid plans are Plus, Pro, and Ultimate. The site is available in English,
German, Italian, French, and Spanish — swap the /en/ prefix below for de, it, fr, or es.
