Master technical analyst Peter Brandt shares his perspective on what he calls the three dimensions of trading psychology—the interplay of an investor’s emotions, characters traits, and strategic rules and approach—and how self-analysis of these facets can start one on the road to real growth. In the course of any investor’s life, Brandt warns against two of the most dangerous scenarios they could face, both severe drawdowns (whether financial or emotional in nature) or severely profitable periods, and he offers advice on how to accept losses, dispels false notions about “win rates,” and shares how to develop an effective process and metrics to keep both one’s emotions and execution of trades in check.
