My trading style is medium term and long term, but for me the real challenge is short term trading, which is what I am learning now, because I see that the results are much faster and that caught my attention, so when I see that things could go more in that direction, I think one should do it, but it should be more focused on technical analysis than on fundamental analysis. The tools used the most are lines, and a lot of technical theory is used. I have not found a book that talks about short term trading.
