The entry decides which trends you join; the exit decides how much of them you keep. A trend follower uses two different exits for two different jobs: the initial stop from lesson 5 cuts losing trades quickly, and a trailing exit stays out of the way of winning trades until the trend turns. This lesson compares the main trailing exits, the cost they carry, and the extras traders add: time stops, partial profits and rules for managing the open trade.
Three ways to trail a trend
Each trailing exit defines "the trend has ended" differently:
| Exit | Rule | Strength | Weakness |
|---|---|---|---|
| Channel | Close below the lowest low of the prior n sessions (the Turtles used 10 and 20) | Follows structure; simple | Short channels exit on normal pullbacks |
| Moving average | Close below the 50-day average | Gives a strong trend room; widely watched | Lags; can give back a large share of the gain |
| ATR trail | Highest high of n sessions − k × ATR, only moving up (the chandelier exit, popularised by Chuck LeBeau) | Adapts to volatility; hangs from the high | Widens after volatility has already risen |
The figure applies all three to the same trade. The ATR trail, tightest on this quiet path, is shaken out in a mid-trend pullback; the 10-day channel holds until near the top; the 50-day average leaves last and gives back a little more. Change the path and the order changes. The useful question is not which exit is best but which one matches the holding period you want: tighter exits produce more, shorter trades and smaller winners; looser ones fewer, longer trades with larger winners and larger givebacks. The averages themselves are explained in moving averages, the chandelier formula in ATR stop.
The cost of letting winners run
A trailing exit can only fire after price has turned, so every winning trade ends below its peak. That giveback is not a mistake to be fixed; it is the price of staying in the trade until the trend is confirmed over.
Traders who cannot accept the giveback often tighten the trail after a large gain. That can be reasonable, for example switching from a 20-day to a 10-day channel once a stock is extended far above its 50-day average after a steep run, but only if the rule is written in advance and tested. Tightening by feel, after a scary day, is the same error as taking profits early.
Time stops
Breakouts that work tend to work quickly. A position that has gone nowhere for weeks ties up capital and risk budget that a fresh signal could use. A time stop closes a trade that has not made progress after a set number of sessions, for example if it is not at least 1R in profit after 10 to 15 sessions. The cost is that some slow starters become large winners after the time stop has closed them. As with every exit rule, the answer comes from testing the system's own trades, not from intuition.
Partial profits: a trade-off, not a free lunch
Selling part of a position at a fixed gain, such as half at +2R or the whole at +20%, raises the win rate and smooths the equity curve. It also lowers the payoff of exactly the trades that pay for a trend-following system.
The figure makes the trade-off concrete for trades that first reached +2R. If the trend then fails, selling half at +2R is better: a trade that exits at 0R earns +1R instead of nothing. If the trend keeps going, holding everything is better: a trade that exits at +10R earns 10R instead of 6R. Since lesson 1 showed that a handful of large winners can produce more than the entire net profit, partial profits can reduce expectancy even while they make the system feel better. Some traders accept that cost for a smoother curve; the point is to choose it knowingly.
Managing the open trade
- Never lower a stop. Stops move only in the direction of the trade.
- Be careful with break-even stops. Moving the stop to the entry price too soon turns many trades that would have recovered into scratches, and removes some of the eventual large winners.
- Decide about earnings in advance. Holding through a report can mean a gap far beyond the stop. Common rules are to hold only with a cushion of profit, to reduce size before the report, or to exit.
- Record the exit reason. Stop, trailing exit, rule exit, target or time stop: the mix tells you later whether the exit is doing its job.
How to apply it
Entry
Choose the exit before the entry. The trailing method, any time stop and any partial-profit rule are part of the system and are not changed during the trade.
Stop
Keep the initial stop until the trailing exit is higher; from then on the higher of the two applies, and it only moves up.
Target
For the core position, none: exit when the trailing rule fires. If you use a target or a partial sale, define it in R or percent and test its effect on expectancy.
Invalidation
The trade ends on the first of: the stop, the trailing exit, the time stop if used, or the target if used. A gap through any level exits at the open.
In Clear Tape
The presets on the Trading systems page use the exits described here. The 20-Day Breakout exits on a close below the prior 10-day low. The Leader Trend Filter exits when any of its eight checks fails at a close or at the ATR trailing stop (22-day high − 3 × ATR(22)). The 52-Week High Breakout exits on a close below the 50-day average or at the same ATR trail. The Volume Base Breakout takes its +20% target when a day's high reaches it, or exits on a close below the 50-day average on above-average volume. The Volume Pivot exits on any close below the 50-day average, and the NR7 / Inside-Day Breakout at a 2R target, its stop or the ATR trail. Stops are checked against each day's low, targets against each day's high, rule exits on the close, and a gap through a level fills at the open. Each backtest lists every trade with its exit reason (stop, target or exit rule), the average days held and the average win and loss, so the effect of an exit can be compared between systems. In the rules builder, exits are conditions such as "close below the lowest low of 20 sessions" or "close crosses below the 50-day SMA", plus an optional target in R or percent; it has no trailing or time stop of its own. Screening and backtests are available to Tools and Pro members.
Common mistakes
- Searching for the exit that never gives anything back; every trailing exit does.
- Tightening stops after a frightening day rather than by a tested rule.
- Adding partial profits without checking their effect on expectancy.
- Moving stops to break-even by reflex at the first small gain.
- Holding through earnings without a plan for a gap.
Summary
Trend followers cut losers with a fixed initial stop and let winners run with a trailing exit: a channel low, a moving average or an ATR trail. Every trailing exit gives back part of the gain, which is the price of staying in until the trend ends. Time stops free capital from dead trades, and partial profits smooth results at the cost of the largest winners; both are trade-offs to test, not defaults. The final lesson shows how to test the complete rule set and run it week after week.
