The Logic of Trend Following
Why Turtle-style systems try to capture large trends while accepting frequent small losses.
Trend following starts from a simple observation: large market moves are hard to predict in advance, but they can sometimes persist after they begin. A Turtle-style system does not need to identify the reason for a move. It needs a repeatable way to participate when price behavior shows strength or weakness.
Asymmetric outcomes
Many breakout attempts fail. Some fail immediately. Others move a little and reverse. The system accepts this because the downside of each attempt is designed to be limited.
The payoff profile aims for asymmetry:
| Trade type | Typical role |
|---|---|
| Small loss | The cost of testing whether a trend is starting. |
| Scratch or small win | A trade that did not develop into a major trend. |
| Large winner | The rare move that pays for many failed attempts. |
Why it feels uncomfortable
The system may be wrong often, then give back part of open profit before exiting a winning trend. Both experiences feel bad. That is why the edge is not only in the entry rule. It is in the ability to keep applying the complete process.
Trend following is a long-series game. It asks the trader to think in distributions rather than single trades.
