Opening a Deleted Chart in MT5
On the MT5 XAUUSD Software when trading if you get to delete a chart or open one that has been deleted unintentionally, you can use option of 'Open Deleted' located on the file drop down menu as the third option on this list.
For example, if you had opened a XAUUSD and had put a set of indicators on this chart, but you had not saved this set of indicators, then you can just use This MT5 option to open the charts named XAUUSD, note there may be 2 or Three or more of the deleted XAUUSD on the list & you'll have to open each until you get the one that you are looking for.
For examples by clicking open the deleted chart this will open this deleted chart that had been closed previously.
Method of opening a deleted chart from the MetaTrader 5 'File' Drop down navigation menu.
If you have deleted many charts this listing will include all of these charts and they will be arranged from the most recent onwards, and as a trader you might have to scroll either up or down in case there are many deleted ones saved within This MT5 option.
