They were probably looking at these areas:-What about the low on Friday?
Was it obvoiusly gonna make that hard move down?
How did people know to wait for the low? (i'd have jumped in long much earlier if not for people telling me to wait)
For example, this person called this around the market open (when price was 3705):

low ended up being 3677.25 followed by a monster rally...
But with that late day rally catching the low, or close to it, was not even necessary. 5 minute 3:45 bar (engulfing previous 18 candle bodies ignoring bottom 2 slightly!!) was all that needed. 9 out of final 12 5 minute candles were black and most were HH's.
