1-2-3 Chart Pattern

Updated: Sep 15, 2020

The 1-2-3 pattern is a common chart pattern which occurs very frequently and has a very high success ratio. These 1-2-3 patterns often form at the beginning of new trends and swings, and they are a strong indication of a change in trend. They can also be found within a trading range, and they take place when the directional momentum of a trend is diminishing. 

We call the 1-2-3 pattern the DNA of price action & the formation of a valid 1-2-3 pattern indicates the beginning of definite patterns to follow.

We are thus looking for bigger moves when we identify this pattern & this has a distinct advantage when used for trading currencies, since Forex tends to have strong trends.

In the illustrated example above, we have a typical 123 formation forming at the beginning of a new uptrend.

If we look at the fundamental reason for the forming of this pattern, we can see why it works so well.


  • The existing (down) trend continues with a formation of a new low (pt.1)

  • There is a breach of the previous high (pt.2) indicating a reversal of the existing (down) trend. At this point, everybody would be going long creating the extra momentum for the upwards trend. This is because trader’s, who had anticipated the downtrend to continue, would have placed their stops above point 2 of this formation.

  • When these stops are hit, these breakout traders will tend to cover their positions by going long, driving the price up with thrust.

  • The final confirmation seen, when there is a failure to make a new low (pt.3)
