Set global variables

If you wish to code in MQL5, you can set a global variable and save it to MetaTrader5 (MT5). Global variables are variables that can be used across multiple programs including Expert Advisor (EA) and indicators. Local variables on the other hand get reset every time MT5 reboots, so use global variables if you wish to save the data for later on. Here we'll take a look at how to set global variables on MT5.

Step 1

Click "Tools" in the menu and select "Global Variables".
