It is real, but it's not something that people are good at or can do in today's world. There are hedge funds out there that make money using technical analysis but it's all automated trading. Machine Learning and other software based techniques work a lot better for technical analysis than fundamental analysis because computers can react instantly and analyze vast amounts of data.

Combine technical analysis with risk/reward calculations. I think that is where people go wrong so often. Over leveraging is the primary way everyone destroys their portfolio.
