DAX (GER40) Lot Size Calculator
The DAX 40 (GER40) is known among traders as "The Beast" for its speed and volatility during the European session. It tracks 40 major German blue-chip companies and requires precise risk management.
GER40 is unlike US indices because its main volume occurs during the European morning (8am-11am London). It often trends strongly before US markets even open. Its tick value is typically in EUR, meaning you must account for EUR/USD exchange rate risk in your sizing if your account is in USD. A 100-point move in minutes is common at the open.
