Trend following uses rules that take exposure in the direction of a defined past price move. The exit responds to a stated change in those conditions. A strategy cannot know in real time exactly when a trend begins or ends.

Choose One Definition

Higher confirmed highs and lows can define an uptrend; lower highs and lows can define a downtrend. A moving-average rule or a breakout above a prior range is an alternative. These definitions can disagree because their lookbacks and timing differ.

For example, “close above the 50-bar moving average” is an observable condition, not proof that the next bar will rise. Keep the bar interval and session fixed. If a swing requires two later bars for confirmation, record it only after those bars exist.

ADX measures a form of directional-movement strength, but a threshold such as 25 is a chosen filter rather than a certification that a profitable trend exists. Check your platform's implementation before using its readings.

Breakout and Pullback Entries Differ

A breakout rule enters after price crosses a prior boundary. A pullback rule waits for a retracement and a specified recovery signal. The pullback may offer a lower long-entry price but never arrive; it can also become a reversal. Neither entry is automatically safer or more profitable.

If you add to a position, calculate combined exposure. The first entry's unrealised gain does not make an addition free. See scaling calculations.

Define an Exit That Can Be Followed

A trailing price distance, a multiple of ATR or a moving-average condition can be an exit rule. Specify when it updates and whether decisions use closed bars. Distinguish an actual working protective order from an alert that still requires action.

Partial exits change the average payoff and remaining quantity. They do not guarantee that the complete position finishes in profit. Monitoring frequency must fit the instrument and account obligations; a weekly check is not suitable for every intraday or leveraged position.

Evaluate the Entire Sequence

A market can repeatedly cross a signal without continuing. Record those losses and the occasional large winner using the same rules. There is no universal 40–50% loss rate, and a few historical winners do not prove they will recur.

Include transaction costs, carrying costs where applicable, drawdown and missed fills. Compare separate market periods and keep a period aside from rule selection. Retrospectively labelling every successful trade a trend and every failure a range makes the test circular.

The moving-average crossover guide gives a more specific rule family to study. Treat any chosen variant as a hypothesis to evaluate, not a guarantee that following price will pay.
