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 minimize 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.
