ESB can log everything from actions, errors, warnings and even indicators data. You can use ESB as a data logger by simply using these options. ESB is the simplest and fastest method for creating a complicated forex data logger.
Log Actions into Journal: This option logs everything in the journal. Every time an error or failure will happen or new action is done, just check the journal to find its complete information about that.
Log Actions into File: This is like the previous option but logs everything in a log file named “<your robot name>_<type>_<symbol>_<timeframe>_<magicnumber>_ actions.log” that can be found in MQL data folder. Go to the “File > Open Data Folder” menu. If you are in strategy tester go to the “Tester > Files” folder and if you are in live mode (real or demo) go to the “MQL4 > Files” folder.
