Tradestation had to do these, so they can rise the price from
$59 to $99
I was already familiar with Easylanguage, so it took me
few days to read it only, the book has little more deciplinary
approach to teaching than other online materials with
examples then exercises
there is something like a 400 page easy language
learning book in pdf format on the net somewhere
its very complete and for free but i cant remeber the url
anymore sorry
ill search and post it if i had any luck finding it
