.CSV Files Editing and Reading

Hi there.

I was wondering if anyone knows how I can Read/Write to a .csv file but to a specific column and row for example E5 , C7 , A1 ...

I have attached the document that I use to calculate my strategy and I want to automate the process. The EA needs to post certain values like High , low , Extry , Exit ... Attached I have the document I use to Calculate everything and hilighted in red are the fields that I want to edit with an EA.

Thank you so much.

MQL4 (EA) is meant to work with the MT4 platform and not as a general purpose programming language. There are lots of other programming languages for that purpose. For your purposes, Excel has its own built in macro programming language which could probably do what you want and is easy to learn.

Except as described in my next paragraph, I don't know how to get MQL4 to read/write Excel files directly, but it can output values to a .CSV file (like you describe). Then, as CodeMeister points out, you'd need a Excel/Visual Basic macro to import the data from the CSV to Excel. Excel falls outside of my area of knowledge.

The attached XLS uses formulae like
=MT4|BID!EURUSD
to gather, and automatically update values from MT4, in real time. I'm not sure exactly how it works, but I believe you need to first press Ctrl-O in MT4, and check ON Allow DLL imports on the Expert Advisors tab.

If your goal is to write an EA, why not operate the other way around, i.e. code your Excel trading rules directly into the EA, and have the latter perform the necessary calculations/decisions, and place the trades for you?
