i just downloaded it but it's a clusterfuck of formulas and i dont think its focused on trading, just financial engineering. Also the pdf i downloaded looks like shit and cant find it in high-res anywhere.

Most of it is about trading! Though a lot is focused on derivatives. And he does a good job of explaining practical applications for most everything he presents. It's my opinion that this is the preferable way to approach the market. But it's certainly not the only way!
Also, for a fun read, I'd recommend Jack schwager's book where he interviews successful traders and hedge managers about their lives and methods. Most of the interviews(i liked Part 3 the best) are super interesting and actually have good information to think about. Here;s a PDF if your interested. https://www.forexfactory.com/attachment.php?attachmentid=1901698&d=1460287011
