It seems easy to spot a trend after it’s ended. But I still have not seen or heard from books and podcasts a formula to detect the beginning and end of trends. Also, I hear people saying stocks are way too correlated to the overall market to be useful for trend following, making the turtle trading rules obsolete. (I’m assuming turtle trading is identical to TF?) My concern is that I’m an absolute beginner. Arguments from both sides of the aisle sound legit to me.
Where is the argument against that?
