Hi - what's the best possibility to trade based on levels given in a spreadsheet with the following information;
I want the flow to be like this;
Is this something that would be even remotely possible to do?
I basically just want to feed my levels into a sheet and have the EA do all the work for me.
Spreadsheets can save in CSV format.
So have your EA read the CSV format.
It's possible to both read and write to files using MQL4 file functions.
Here are the File Functions available for MQL4:https://docs.mql4.com/files
If you are reading the whole file and writing the whole file, you won't have any difficulties.
If you want to update specific cells of a spreadsheet, that gets trickier. In that case, perhaps a DDE solution is preferred. I haven't done DDE with MT4, so I have nothing to offer there.
