Your complaint has to do with Technical Analysis in general rather than Hive account@haejin's application of it. All the analyst does is apply the principles as they see fit.

Even if TA has little merit in the practical sense, it provides the user a calmer appreciation of price movements - and in this sense it gives the investor a better starting point from which to invest. So from a purely psychological standpoint, I understand how it helps people cope with the stress of investing. I'm not totally convinced that TA really has some basis, but the point of watching these videos is not to follow them blindly, but trying to find value and disagree/agree as you see them.

To me at least, whether or not he is accurate is besides the point of these videos.
