I started trading only 2012 but i took stock trading courses as well as spend over 13 hours a day researching trends and companies financials, charts, etc. Trading stocks is most addictive yet rewarding job i have ever done!
Dan has been active in finance, strategy & business building for more than two decades. He has focused on technology & media for most of that time. His notes are here & in his book, "Tools for a New Trade"
Interested in trading systems since 1996... in early to mid 2016, I completely stopped trading individual stocks barring a few small trades in long term accounts. After much research & backtesting, I now trade a SPY option spread system. Good luck!
