I don't think that you should be as worried about finding the next big winner. Pick one or two and work with them. If you want to hold a little back so that you can average down then so be it.
And I don't think you should worry as much about how fast things move on the board here. Understand that some folks that are leveraging more will get in and out faster because they have already made enough to cover their trade. 6% of 5K is 300 bucks where 6% of 500 is only 30. That is part of the problem with over diversifying. Figure out what is enough for you to make it worth your time. Do the math before you buy it.
I do think that you should study your charts and how to read the indicators. You have to understand what they mean and pick the ones that you rely on. It seems like if you ask 10 different traders which indicators they use then you will likely get 10 different answers. Know why you are buying a stock (and not just because you got an email about it) and know why you are selling it.
I will gladly hold a stock for a week or more if it is still gradually climbing each day. I know that it does add up. Maybe it isn't as glamorous as the 10 baggers but I am making money. I really believe in the pinchers and I think if you apply them properly then you will make money. Of course that is my opinion and should only be taken as such. GLTU.
