<<<1.-What do you want to learn about day trading?>>>
It changes as years goes by, beginning you think entry, later is stop loss, then duration to change to defensive attitude (getting out with tick profit), take opposite position of retail, eventually you have developed one heck of knowledgeable Trading Plan.
<<<2.-What are the biggest hassles or challenges you have experience with day trading?>>>
Lying to myself in the beginning, thought I was getting good, "am so close", LOL Perhaps only for me, learn chart reading was not enough to learn scalping, there is timing, click, click, click. Discovering I was one messed up human being-happens from handful of continual losing years-more a challenge to slowly overcome, you evolve-adapt-change your thinking and often other parts of my personality, you really have to think outside the bun.
<<<3.-What do you think would be the most helpful as you are learning about day trading?>>>
When I started I had to call the floor, so I think now it should be easier-but it is not, people are too lazy to learn for few years, you have quicker data and you can back test and paper trade till you triple demo account three different times before you go live. No larger than $5,000, bigger account you will just lose more. Keep it small, makes you keep your focus tight. Read some of the books, then never take the entries they show, find out where retail is getting out and you take other side. Retail often has too tight of protective stops. Back test extremely well.
