I have been absent of this journal for a while because I have been transitioning from global macro to day trading and swing trading. When I started I wanted to learn from other traders to make sure I knew the fundamentals down so I wouldn't struggle but very short-term trading (which I had attempted in the past unsuccessfully).
I decided in 2012 that I wanted to write a book about traders where I would interview a bunch of successful guys and learn as much as I could from them, market wizards style
After a ridiculous amount of working Sundays I finally put it out and it is now listed on Amazon

I can say that after day trading for almost 2 years now (full-time), it helps one trading style tremendously. First because you have to be way more disciplined. In global macro you can frequently get away with lack of discipline because you only make a few decisions a year, if your style will blow up one day you might only find out in 5 years. In day trading if your style is headed towards a blow up it shouldn't take that long for you to turn your account red.
It also teaches to respect the price action more. Michael Markus says the best trades are a combination of fundmentals, technicals and market tone. With my previous style I was too focus on fundamentals, that can work too but its just superior to have a combination of them all because you dramatically can lower your risk/vol.
Day trading is like going to the gym hard while longer-term stuff is more like jogging, You can improve faster and reach new levels of skill. You can also blow up faster, that's why I wanted the right information from other traders on how to do it and wrote the book.
Anyways, just wanted to let you guys know
