By default, the real-time data for securities is from the German Lang&Schwarz Börse (L&S Exchange) or the Stuttgart Stock Exchange and all other time periods are automatically retrieved from the respective home exchange if possible and as well as converted into your default currency.
Contributing Factors
Several factors contribute to differences in the display of data between platforms:
Spreads: Variance in buy and sell prices between different exchanges can impact calculations.
Currency Conversion: Fluctuations in exchange rates and differences in conversion methods can create discrepancies.
Rounding Differences: Inconsistencies in rounding algorithms can cause minor deviations.
Data Delays: Different update frequencies and delays in data sources may reflect as inconsistencies.
Therefore, it is possible that some difference exists with your broker's data if they use a different exchange or currency conversion.
Typical scenarios include divergences with broker data due to different sources or calculation methods and exaggerated differences during intraday fluctuations caused by real-time market movements.
