Hi Oba,

You really the first one said Thanks and I appreciate that very much.
About the email forwarding of my lessons, I promise you I'll tell the administrators about your good hint.

Did you read the "welcome" lesson? do you have any quesiotns?
I welcome any questions and suggestion, that's the only way the COURSE going wider.

Coder's Guru

Great Thanks

I wish to thank you for your work.

I have not taken the time to learn because I was not sure where to start and felt alittle intimidated by programming in general.

But having it handed to me on a silver platter like this mean I no longer have a excuse.

This is a valueable resource.

Thanks, Stephen

Hi audio,

"MetaEditor.exe" is a program enables you to write MQL4 programs(Indicator,Expert Advisors..etc) and compile them.
You will find "MetaEditor" at the same path of MetaTrader 4 installed path, which usually "C:\Program Files\MetaTrader 4\MetaEditor.exe"

Please read the lessons and you be able to write and modify MQL4 programs.

Any question do not hesitate to ask me.

Thanks for making all those lessons. I was really bangin my head on the preprocesssor directives, but you smoothed it all out for me.

THANK YOU, CODERSGURU !!!

Coders guru,
I add my thanks to the others. What a wonderful act of generosity this is!

I have picked up a tiny error for you: in Q2 part 3, and in it's answer, there is a typo- metalang.exe vs metalnag.exe.
