Barrier:
"a fence or other obstacle that prevents movement or access".
What is bartier here?
Here there is something on the left that hold price(buyers orders).
How price pass this barrier?
To pass from here it does need to clear all orders standed in this area.
When they concumed all orders and price pass this area we then have a new zone that act in opposite direction.
That time it was buyers station to hold price and stop it but after clearing it is sellers station.
When price break an important sup-res or pass important buy or sell zone creat a flag that contains sevral smaller flag inside it .
Each of this tiny flags runs price toward target.
Each one is for a reason.
Good luck traders
