SmartDataExportEa – Your Ultimate Data Export Tool for MetaTrader 4 |
---|
EA Description
SmartDataExportEaMT4 is a data export tool designed exclusively for MetaTrader 4. This EA does not perform trading operations; instead, it specializes in exporting market data and key indicator values in CSV format. It is the perfect solution for traders and developers looking to streamline data analysis and strategy development.
Integration with Real-Time Analysis
When you export data in real-time, the CSV file can become locked, making it difficult to run the EA and analyze data simultaneously. To address this,
this tool intentionally uses a mechanism that “acquires historical data in a manner close to real-time”, so that the CSV file is not locked. As a result, it enables pseudo-real-time analysis.

Feature Details
-
Comprehensive Data Analysis
Generates CSV data combining various indicators and market data, making it an ideal tool for traders, algorithm developers, and data analysts. -
Flexible Configuration Options
Freely configure any timeframe, number of bars to export, and export intervals. You can customize it to match individual needs. -
Manually Calculated Bollinger Bands
Computes Bollinger Bands (Upper/Mid/Lower) using a high-precision custom logic. -
Simple CSV Output
Exports data in CSV format, easily usable in external tools such as Excel or Python. -
No Interference with Trading
Since this EA does not execute trades, it supports data analysis without interfering with existing trading strategies. -
Integration with Real-Time Analysis
To avoid file locking issues when exporting data in real-time, this EA deliberately employs a system that “acquires historical data in a near-real-time manner”. Because the CSV file does not become locked, pseudo-real-time analysis is possible.
Usage Guide
Step 1: EA Installation
- Open MetaTrader 4.
- Click [File] → [Open Data Folder].
- In the opened folder, locate the MQL4/Experts folder.
- Copy the SmartDataExportEaMT4.mq4 file into the Experts folder.
- Go back to MetaTrader 4, right-click [Expert Advisors] in the [Navigator] window, and select “Refresh.”
Step 2: Configuring and Starting the EA
-
From the [Navigator] window, drag “SmartDataExportEaMT4” onto your chosen chart.
-
The parameter setting screen appears. Configure the following:
Parameter Description Default Timeframe Select the timeframe to export (e.g., M1, H1). PERIOD_M1 NumberOfBarsToExport Specify the number of bars to go back for export. 3000000 ExportIntervalSeconds Interval in seconds at which data will be exported. 900 (15 minutes) -
After configuration, click “OK” to enable the EA.
Step 3: Checking the Exported Data
- Once the EA is running, it will export data in CSV format at the specified intervals (e.g., every 15 minutes).
- The generated CSV file is saved in the MQL4/Files folder under MetaTrader 4’s “Data Folder.”
- File Name: The exported file name is fixed as SmartDataExport.csv.
- Overwrite Specification: If a file with the same name already exists, it will be overwritten with new data. If you wish to keep the old data, rename or back it up during the export interval.
Step 4: Utilizing the CSV Data
The exported CSV data can be used as follows:
- Open in Excel: Visualize and analyze the data easily in a spreadsheet.
- Analyze with Python or R: Integrate into statistical or machine learning models.
- Strategy Development: Use it for backtesting or verifying trading strategies.
Step 5: Stopping or Removing the EA
- If you want to stop the EA, click the “Smile icon” at the top-right corner of the chart, or right-click on the chart, select [Expert Advisors] → [Remove].
- Even if you remove the EA, the CSV data that has been exported remains intact.
Test Mode
This EA includes a customizable Test Mode (UseTestMode).
When Test Mode is enabled, the number of bars retrieved may be reduced and the export interval extended to reduce load in the Strategy Tester. This helps prevent timeouts or performance issues during backtests.
When UseTestMode is set to false, it will export a larger number of bars and update data at shorter intervals, providing full functionality.
Important Notes
- Stable Network Connection: A stable internet connection is essential.
- VPS Recommended: For long-term operation, running on a VPS helps prevent export interruptions.
- Check MetaTrader 4 Settings: Ensure automated trading is enabled. If it’s disabled, the EA won’t run.
- Overwrite Behavior: Since the CSV file is automatically overwritten, back it up if you need to keep past data.
- Broker and Local Limitations: Due to certain broker or local settings, you may only be able to retrieve about 2100 bars. If you need more data, please use our MetaTrader 5 version, which often allows acquiring over 100,000 bars, depending on the broker.
FAQ
Q: No CSV data is generated. What should I do?
A: Check the following:
- Is the EA properly applied to the chart?
- Do you have the proper write permissions for the data folder?
- If the export interval is too short, try lengthening it.
Q: Can I retrieve data for other timeframes or symbols?
A: Yes, you can change charts or settings to adapt to any timeframe or symbol.
Q: Can I change the output file name?
A: Currently, the file name is fixed as SmartDataExport.csv. Please rename it manually if needed.
Q: How can I save the overwritten data?
A: Back up or rename the file during the export interval if you need to keep old data.
Q: Why are the first 20 Bollinger Band bars output as 0?
A:
Bollinger Bands require the previous 20 close prices for calculation. Therefore, for the first 20 bars, the required historical data is lacking, resulting in 0 output. This is normal operation; from the 21st bar onward, valid values are output. If Bollinger Band values are needed for all bars, it is recommended to set the number of bars to be exported at least 20 more than you need.
