MT5 Historical Data Export Script
Export MetaTrader 5 candle history into clean OHLC CSV files for Python research, EA validation, backtest comparison and machine-learning experiments. This page explains the workflow and the common mistakes that break trading datasets.
What the Export Script Is For
Export candle data from the same broker feed you use for MT5 Strategy Tester comparisons.
Create CSV files that can be loaded into pandas, scikit-learn, notebooks or custom analytics.
Compare your EA entries against exact OHLC candles instead of guessing from a chart screenshot.
Use an append process to extend a dataset without manually merging duplicate rows.
Recommended Export Workflow
- Open the symbol and timeframe in MetaTrader 5, then load enough history from the broker.
- Run the OHLC export script on the chart and save Timestamp, Open, High, Low, Close, TickVolume and Spread.
- For updates, use the append script instead of creating a second file with overlapping candles.
- Run the output through the CSV Data Quality Checker.
- Use one naming convention such as
SYMBOL_TIMEFRAME_OHLC.csvso Python and MT5 workflows stay organized.
Common MT5 CSV Export Mistakes
XAUUSD, XAUUSDm and XAUUSD.pro are not always identical feeds. Store the exact symbol name.
MT5 candles use broker server time. Convert carefully before comparing with TradingView or another broker.
Appending without timestamp checks can double-count bars and distort indicators.
Gold scalpers and pending-order systems can look profitable until realistic spread is included.
Python Validation Snippet
import pandas as pd
df = pd.read_csv("XAUUSDm_PERIOD_M30_OHLC.csv", parse_dates=["Timestamp"])
df = df.sort_values("Timestamp")
duplicates = df["Timestamp"].duplicated().sum()
bad_ohlc = ((df["High"] < df[["Open", "Close"]].max(axis=1)) |
(df["Low"] > df[["Open", "Close"]].min(axis=1))).sum()
print("Rows:", len(df))
print("Duplicate timestamps:", duplicates)
print("Bad OHLC rows:", bad_ohlc)
Need Broker-Specific MT5 Data or an EA Built From It?
I can prepare broker-specific export scripts, automated data appenders, Python research notebooks, Strategy Tester comparison reports, and MT5 EAs that use the same symbol, timeframe and risk model you tested.
