Common Misconceptions
Common misunderstandings about trend following and the Turtle Trading method.
Many problems with Turtle-style systems come from expecting them to behave like something else.
Misconception: a breakout predicts a trend
A breakout is only a trigger. It says that price has moved beyond a recent boundary. It does not prove that a trend will continue. The system survives false breakouts through position sizing and stops.
Misconception: a good system should win most trades
Trend following can be profitable with a modest win rate if winners are much larger than losers. The psychological difficulty is that the trader must sit through many ordinary failures without abandoning the rules.
Misconception: parameters are the edge
The exact window length matters less than the robustness of the rule family. A trader who changes parameters after every losing period usually creates curve fitting rather than improvement.
Misconception: profit giveback means the exit is bad
Trend exits usually give back part of open profit because they wait for evidence that the move has weakened. Exiting at the perfect top is not the goal. Capturing a meaningful part of a large trend is.
Misconception: automation removes discipline problems
Automation can remind, calculate and record. It cannot replace risk limits, market selection, data checks or the decision to follow the plan during drawdowns.
