Convert past data
Download PeriodConverter_rcm.※One-Click FX Seriesis included, so downloading is not necessary.
1.Close all charts, restart MT4then open File -> Offline Charts from the menu. From the list, select the 1-minute chart and click Open. The image shows the 1-minute offline chart for USDJPY. (In the latest version, the normal 1-minute chart also works, but offline charts are more reliable.)
2. On the opened offline chart, right-click => Template Chart, then click “Convert past data.”
3. PeriodConverter_rcm displays the start date for converting the 1-minute data. If you want to begin, please answer Yes.
4. When you press Yes, the 1-minute data will be converted to 5-minute, 15-minute, 30-minute, 1-hour, 4-hour, daily, weekly, and monthly bars.
5. When the conversion finishes, the above message appears. Restart MT4 and check the chart historical data.
If you restart now, you will see a prompt asking “Generate data?” or similar; press No, or close the chart if past data has been generated correctly.
If past charts cannot be generated correctly, restart MT4 and repeat the same process. Since MT4 saves data on exit, data may be overwritten at shutdown. Therefore, the procedure requires restarting MT4 to ensure data is reliably saved.
We have developed various methods in the past to reliably reflect past data, but this method is simpler, and if uncertainty remains, it shows a message to reduce effort significantly.
