Preprocessing recommendations

  1. Verify and normalize timestamps to UTC.
  2. Remove or flag duplicate ticks and outliers.
  3. Resample ticks to desired bar size with OHLCV logic (use bid/ask rules consistently).
  4. Handle weekends/holidays by filling or excluding ranges per strategy.
  5. Adjust for spread when using bid/ask vs last price.

Part 7: Common Pitfalls (Don't Ruin Your Backtest)

I have mentored dozens of traders who blamed the market for their losses, but they actually just used bad data. Avoid these mistakes with Dukascopy Historical Data:

  1. Ignoring the Ask Price: Many amateurs only download "Last" or "Bid" price. In Forex, you are always selling the Bid and buying the Ask. Ignoring the spread means your backtest thinks you buy and sell at the same price (infinite profit). This is deadly.
  2. Look-Ahead Bias: When you download data from Dukascopy's server, it is the final, closed candle. In live trading, the candle changes. Ensure your backtest engine processes ticks sequentially.
  3. Timezone Hell: Dukascopy uses server time. If your strategy uses London or NY open, you must convert timestamps to UTC or EST.
  4. Survivorship Bias: Dukascopy still provides data for dead instruments (like EURCHF before the peg was dropped). Be careful analyzing historical pairs that no longer exist.
