Wow, I did not know it was a thing, thanks for sharing this. The account doesn't exist anymore, but the problem could be common. I don't trust technical analysis, and I don't believe anyone can systematically make good predictions based on it or anything else, but I know that many people trust this stuff, and photoshopping the trades to look more successful is outrageous in any case. It's funny how the article ends by Canfield promising to stream his future trades, but his Twitter account is deleted.
It's also worth noting that the tweet by King says that this Canfield is a scammer whereas whoever did the TA for him isn't. In a way, isn't all TA a scam, just a more hidden one (kind of like fortune-telling and stuff)?
