How to Access Dukascopy Historical Data

Despite its high standing, the use of Dukascopy historical data is not without challenges. The sheer volume of tick data creates significant technical hurdles. Processing years of tick data for a single currency pair requires substantial computing power and efficient database management. Furthermore, like all historical data, it is susceptible to "survivorship bias"—the data set typically only includes currency pairs or assets that are currently active, ignoring those that may have been delisted or became irrelevant. Additionally, while Dukascopy’s spreads are generally tight, historical data does not always perfectly capture the "tick volume" in the same way centralized exchanges like the NYSE do, as Forex is an over-the-counter (OTC) market.
