dear vishal,
suppose u start looking at chart from 1st june...
on 1st june u see no box on 1st june bar..
then 2nd june price going up.. still no box sign
3rd june up again.. still no box sign
on 4th june suddenly we will see BLUE BOX SIGN ON 1ST JUNE BAR
so on 4th june u recognize that the uptrend strated from 1st june...
thats how it work.
but in FEW cases u can face problems....
how is that?
now from 4th june u know trend is up...
so u buy..
on 5th june u see price going down... and still blue box in 1st june bar..
6th june.. price going down more... and still blue box in 1st june bar..
7th june more down.. and still blue box in 1st june bar..
on 8th june u suddenly watch PINK BOX ON 4TH JUNE BAR!
i think its now clear what i mean by "it only comes after3/4 bars "
