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.
