Dukascopy historical data is an invaluable resource for the retail algo-trading community. The data quality rivals paid services, but the user experience is stuck in the early 2000s. If you are willing to tolerate the clunky download process (or write a script to bypass it), it is the best free data source available.

Most free historical data sources only provide the "Bid" price or a "Mid" price, forcing traders to simulate or guess the spread. Dukascopy saves both the Bid and Ask prices for every tick. This feature is critical for understanding the true cost of trading during high-volatility events, such as news releases or market opens. Massive Asset Coverage
