Hello,
I would like to add a few lines on this.
I'm not an experienced programmer but I have to say that I picked up
AFL very quickly. Being an array processing language is very easy for
someone that uses Excel, for example.
The user guide with all the tutorials makes the learning task easier.
The only thing that I would like to see more examples of, is the
Custom Backtester to allow unexperienced programmers like me to code
more advanced stuff. I hope that the users knowledgebase can help on
this....
I'd glad that there are books like QTS (which I already own) and
the new one which is coming in 2008, to build a more stronger
community of users.
