1.  Most ppl can't get their head round it. It needs too much experience and analysis. The market moves in waves : each wave sets up the preconditions for the next.

2.  That is the best simple advice.


and 3. See my post just above,  re keeping it simple.


edit :

I just realised that worth adding a note on contrarian logic, for those that dont know :

Bull markets climb a 'Wall of Worry'

Bear markets flow down a 'River of Hope'


Thus sentiment is a contrary indicator.  The majority of sentiment does not change overnight, and a lot of 'work' is need to be done by time and price, before the herd changes its mind.
