Yes, I certainly have to agree with everyone's thoughts on MetaQuotes documentation as well as support.
A great many cries for help go left unanswered on their own forums, their staff often border on being rude (I guess that's the issue with poor English skills on their part), they seem resistant to implementing new features despite continual user feedback and they have never replied to any emails I've ever sent.
I really like Metatrader as a stable platform with a strong scripting backend but there'll come a day soon when a better one will come along by a company who listens to users. MetaQuotes will pay the price unfortunately.
Learning to program MQL? Yeah, join the club on the slow road to picking it up. It certainly isn't easy. The last time I coded was Assembly back in the Z80 days - it's taking me a while but I'm getting there slowly.
Cheers
