As someone mentioned earlier in the thread, the first bottom (or first top) is usually not the lowest bottom (or highest top). A slightly higher bottom after what then becomes the low of the day is generally a strong buy signal; set your stop just below the LOD. (Opposite for shorting - a slightly lower high is a strong short signal.)
anyone can do this after the fact. there is no secret to learn here you either have the talent and vision or you dont. Sure you can gain the talent,may be lots of screen time.
