Basic Chart Pattern is very effective

Hello Traders !

I ussually use basic chart pattern on my technical analysis. I think it's very useful for traders. Many trader still use it and CMT book still write and train it for many student in the world.
Some chart pattern which I appreciate like as :
1/ Head and Shoulder
2/ 2 Top -2 Bottom
3/ Flag pattern
4/ Wedge

Example, Gold chart (h1) as bellow, I use only 2 top-2 bottom to trade and you can see that it is very effective.
