# Trend following

> Trend following is a rules-based strategy that enters in the direction of an established move and stays in it until a predefined exit triggers. It makes no forecast about where price is going and no judgement about value; it reacts to what has already happened. Most individual trades lose small amounts, and the strategy depends on a minority of long-held positions paying for all of them, which is why cutting a winner early is more damaging here than taking a loss.

## How it is calculated

```
Trend following is defined by its exit, not its entry:
  · Entry — a breakout, a moving-average cross, or a volatility band
  · Stop — the loss that ends a trade that never trended
  · Trailing exit — what gives back part of a winner to keep the rest

Win rate is typically ~30–40%. The largest handful of trades carries the whole return.
```

## Most trades lose, and that is the design

A typical trend-following system wins on roughly a third of its trades. The distribution is deliberately skewed: many small losses at the stop, and occasional very large gains from a move that keeps going. This is the opposite of a high-win-rate system, and it means the equity curve spends long stretches flat or drifting down between the few trades that matter.

## Choppy markets are the tax

A trend-following rule cannot tell an emerging trend from noise, so it enters both and lets the exit sort them out. In a range-bound market it is repeatedly stopped out, and that sequence of small losses is the cost of being positioned when a real move finally starts. The cost is unavoidable rather than a flaw to be optimised away, and optimising it away is usually how a system gets overfitted.

## How it gets misread

Trend following is often confused with prediction. It forecasts nothing: the entry is a reaction to a move already visible, and the exit is a predefined rule rather than a view about the top. Judging it by win rate rather than by the size of its largest winners misreads the strategy completely, because the whole return comes from a handful of trades.
