ive been slaughtered many times trying that bottom picking thing .so now a days i try to look for signals and conformation very well said and explained by mushashi .
all the points you mentioned is valid ( bollies not being reliable too lol ) but i try to think i am the dumbest person while trading and not the smartest one ahead of the herd.that way i usually follow the trend :)
BKY - looks good .follow the trendline . and watch out for the resistance area.
WRG- i see the gap straight away .and the bearish engulfing after that big green candle.had a quick look at the company and saw a recent placement @ 0.06. wouldnt hurry buying it imo.
NUP- yesterday's long wick got chopped off today.overall trend looks upeward .keep and eye on the open tomorow .good pick up btw :p
