I found both the wiki and the original mq2 manual earlier on invaluable resources, but I wouldn't of gotten anywhere without looking through other peoples macro code.
If I didn't know how to do something, or couldn't work out how I should do something I would look up similar macros and read through them. As you learn more and more, reading more macros you tend to be reading for how your logic should work as opposed to how the TLO's are used etc.
I credit pretty much everything I know to the people on this site and some others.
I am not a coder/IT guy by profession, I am a nurse... so glad for all the documentation and information sharing here and elsewhere.
