Using Probability and Discipline When Trading Technical Signals
Summary
The article argues that markets are uncertain and that technical indicators cannot deliver dependable forecasts by themselves. It makes the broad claim that trend-following indicators may have accuracy below 50%, attributing this to lag and uncertainty, but it supplies no dataset, test design, or performance results to establish that claim. Its discussion of subjective chart interpretation, including divergent readings of wave patterns, illustrates how analysts can reach different conclusions from the same market.
The practical emphasis is on treating trading outcomes as probabilistic and maintaining consistent execution despite losing streaks or tempting early profits. The article describes a trader using dice to choose among alternatives and practicing card games to become more comfortable with random outcomes. These anecdotes illustrate the argument, but do not demonstrate a profitable strategy or a measurable forecasting edge. The article also does not distinguish signal hit rate from expectancy, so its headline accuracy claim should not be taken as a general result for all indicators.
Key ideas
- The article presents markets as probabilistic rather than precisely predictable.
- It claims trend indicators can have sub-50% accuracy but gives no supporting tests.
- Subjective interpretation can produce different readings of the same chart.
- It emphasizes discipline in following a trading process through uncertain outcomes.
- Dice and card games are offered as anecdotes for practicing acceptance of randomness.
