Thanks dude.

Please download the new lesson and tell me what do you think?

 

This is agreat course. I went through the lessons until the first custom indicator. I have some understanding, but not thorogh. I hope in due course I will get the hang of it. THANK YOU CODEGURU for putting together this course.

I tried to convert one of my simple indicator from mql2, but there is something wrong. Can you check it?

Thanks Codesguru, it is working now. I realize my mistake. Looking forward to your future lessons on Indicators.

 

Thank You!

Coders' guru,

I am very new to metatrader and know very little about programing. I was looking for info on programming in metatrader. And came across your course (which made me decide to join). I look forward to learning from your course and your posts!!! Thanks again!

 

You're welcome.
