Thread: MetaTrader 4 programming guide

Thanks Funyoo....Bill

Hello, Funyoo.

I know that you are very busy as Admin but could you please direct me to
how I can compile an MQL4 program so that I can get the .ex4 file. I am
getting a "could not launch the compiler".

Thanks for your help and reference

Hi, I can't open the pdf in the 1st post. My Adobe reader says that the file is corrupt. I have re-downloaded 3 times but same thing every time.
Would it be possible to check that the file is O.K. and re-upload if it is not.

Cheers, Pye

Pye, It downloads for me...(and it is a very good guide)....You may have other troubles. BillR

Cheers, - Yeah it's weird. I normally use Orbit download manager however I think there is a bug with it because if turn it off & download the pdf normally it opens fine. Thanx for your post.

thank you Mr funyoo for this file
it give valuable info.
