Yeah, the content almost said it all. Just don't forget, it all ends up on decision making. It must be the main thing to consider since every each of us, or traders have their own decision on when to buy, sell and stop.
You cannot reach a decision to invest without knowledge on how and why and when to invest, that article is great really deserves merit and promotion, I have seen a lot of videos on Youtube with the same guide but I always prefer something that is written like yours, it's easy to understand.
