Looks like with this statement you reject a whole trading theory combined with financial analysis and statistics
And what if I wandered to the part of the park where it's not raining with money and I'm trying to get out of here to more rainy areas?
actually it wasn't my saying. It was a quote from a long standing member (not me). and it was more out of irony however in its simplicity the quote is very true
we don't know what's going to happen..but that doesn't make it gambling (unless you stick your finger in the air and think, i'll go long today). we don't know what's going to happen, but we use whatever probability that something that may have happened in the past is going to happen again. which is the philosophy behind technical analysis.
whatever method you subscribe to, be that gann, fibonacci, random straight lines etc etc we use that method because it represents a possible explanation as to what is happening in the market. do we know why? of course not, because everything that happens is a culmination of thousands of different participants and we could never try to know, but we just try to rationalise and make sense out of it and we do that based on statistical probability
do we care whats going to happen next, again no we shouldn't care. if we care, we're probably placing too much emphasis on trying to predict and we shouldn't be trying to predict
we should just be trying to trade whatever methodology you or i or anybody else (and it really doesn't matter what that is) believe in, that works for us and gives us that edge (statistical probability of an edge) that hopefully has been backtested and that you rely on.
it doesn't make one method better than another, how late it is getting in and out of the position, what matters is that it works for you and gives you an edge.
so, is it going to rebound? we don't know and we don't care we are just going to follow our method.
so i would say, look to find a method. a method that works for you and a method that statistically gives you an edge and don't worry what the market is going to do tomorrow, just focus on what its doing now, and what that means to your methodology
anyway, when you say "rebound" all this depends on the timeframe. some would say its an uptrend so is your rebound back down? or is it back up, which is a longer term perspective and all this depends on your method
hope this all makes sense
