CMT is arguably useless. If you really want to be a master at technicals, my recommendation is to pick up python or r so you can run tests. A few years ago, I was working at a fund that was testing momentum strategies. Some of the team (led by phd's) built an AI model that would find patterns in the market and define the probabilities of profit from each one. While the analysis looked amazing using historical data, out of sample and live testing revealed that there was little to no returns when using pattern recognition from charts (candle sticks). However, during their analysis they were able to find new insights into the momentum factor, and they now run a CTA using their research (which constant modifications/tweaks). The tools they used were mostly all free (outside of a bloomberg terminal, which wasn't very helpful for their analysis). Python + t&s data.
