I still got confused on you explanation, meaning all I need to is to set the amount in which I think I will be loss. At least if goes down rapidly I am safe for the huge loss. Is that what you're talking about? Just all I know is there many sellers I will sell then if there many buyers I
will buy coins, just simple as that.
Even not rapidly, once your analysis goes on the other side, or if you do chart, once it becomes invalidated(e.g. broke support/resistance, pattern didn't go on what you expected)
Doesn't mean there are many sellers it will go down, or vice versa with buyers, there are many fake huge sell/buy orders just to fool other traders.
