Here is a look at the 123 bottom chart pattern.
Point #1 is the low of the down move.
Point #2 is the first rally off the low.
Point #3 is the higher low made, after the first low is in.
When you spot a 123 low, that tells you that a market low could be in,
and is very important information when trading.
When a 123 bottom is formed,
the buy point is a move above point #2,
with a stop if wrong below point #3.
