Actually, for the education of forex trading, the available books must be published on the open market in the world so that educated people can know to buy this book. It is difficult to collect forex trading information from online. So, these books must be published in print. and I think it's not so fierce if a merchant downloads many e-books on a computer, and finally, they are afraid to read so many books. In my opinion, try searching for disks online, and save e-books there, read one by one, before reading the e-book, try searching on the internet, there are several reviews, read and decide whether we should read or not.
