nope never.
Trend analysis for me is:
is the last high, higher than the previous high?
-check
is the last low, higher than the previous low?
-check
....therefore we are in an uptrend.
direct opposite for downtrend.
actually draw lines on your chart along the tops and bottoms (print out the chart and use a pencil, it's great practice)...
that's about it.
and if you have overnight exposure in a stock, you have to know fundamentals, (IMO)- at least a general understanding of what the possibilities of where the price can go
... that's just my opinion though
