What are offline charts?
In MetaTrader 4, an offline chart lets you continue to refer to a chart, for example for research or analysis, without any updates taking place. To create an offline chart, follow the below steps:
When a chart is open, click File from the main menu, select Save As and save the file to the desired location.
Close the MT4 platform then reopen it – the chart should still be displayed. You can minimise the chart but do not close it.
Click File in the main menu, then ‘Open Offline’ and select the saved chart to view it in offline mode.
