How this service works
Maximaler Drawdown. Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.
Output

Example use cases
Backtest risk evaluation for strategy
“I just finished backtesting my momentum strategy and I have the daily portfolio values. Can you calculate the maximum drawdown from this equity curve: [100000, 103000, 107000, 98000, 95000, 99000, 112000, 105000, 108000]?”
Risk reporting for fund investors
“I need to report the maximum drawdown for our fund this quarter. Here are the end-of-week NAV values: [1000000, 1020000, 985000, 960000, 975000, 1010000, 1050000]. What's the max drawdown?”
Comparing trading systems by drawdown
“I want to compare two of my trading systems by their worst drawdowns. For the first system, the equity curve is [50000, 52000, 48000, 45000, 47000, 53000]. Can you tell me the maximum drawdown?”
