Success in trading is a function of talents and skills – Trading, in this sense, is no different from chess, Olympic events, or acting. Inborn abilities (talents) and developed competencies (skills) determine one’s level of success. From rock bands to ballet dancers and golfers, only a small percentage of participants in any performance activity are good enough to sustain a living from their performances. The key to success is finding a seamless fit between one’s talents/skills and the specific opportunities available in a performance field. For traders, this means finding a superior fit between your abilities and the specific markets and strategies you will be trading. Many performance problems are the result of a suboptimal fit between what the trader is good at and how the trader is trading.
 The core skill of trading is pattern recognition – Whether the trader is visually inspecting charts or analyzing signals statistically, pattern recognition lies at the heart of trading. The trader is trying to identify shifts in demand and supply in real time and is responding to patterns that are indicative of such shifts. Most of the different approaches to trading–technical and fundamental analysis, cycles, econometrics, quantitative historical analysis, Market Profile–are simply methods for conceptualizing patterns at different time frames. Traders will benefit most from those methods that fit well with their cognitive styles and strengths. A person adept at visual processing, with superior visual memory, might benefit from the use of charts in framing patterns. Someone who is highly analytical might benefit from statistical studies and mechanical signals. 
Much pattern recognition is based on implicit learning – Implicit learning occurs when people are repeatedly exposed to complex patterns and eventually internalize those, even though they cannot verbalize the rules underlying those patterns. This is how children learn language and grammar, and it is how we learn to navigate our way through complex social interactions. Implicit learning manifests itself as a “feel” for a performance activity and facilitates a rapidity of pattern recognition that would not be possible through ordinary analysis. Even system developers, who rely upon explicit signals for trading, report that their frequent exposure to data gives them a feel for which variables will be promising and which will not during their testing. Research tells us that implicit learning only occurs after we have undergone thousands of learning trials. This is why trading competence–like competence at other performance activities such as piloting a fighter jet and chess–requires considerable practice and exposure to realistic scenarios. Without such immersive exposure, traders never truly internalize the patterns in their markets and time frames.
