A breakout happens when price leaves a range or crosses a level that has contained it. Most large trends begin with one, which is why breakouts attract so many traders. Most breakouts also fail or stall. The rulebook of Clear Tape's 20-Day Breakout preset states it plainly: in ranges and whipsaws, often fewer than 40% of trades win, and a few large trends pay for many small losses. Trading breakouts well therefore means two skills: filtering for the breakouts most likely to continue, and recognising quickly when one has failed, which is itself a trade.
What makes a breakout valid
A breakout should pass three tests on the day it happens:
- A close beyond the level. An intraday move through resistance that closes back below it is not a breakout. Many traders also add a small buffer, such as 0.25 ATR, so that a close a few cents beyond the level does not count.
- Range expansion. The breakout candle should be wider than the recent candles, often at least one ATR, and close in the top quarter of its range. A narrow candle that barely clears the level shows little urgency.
- Volume. Volume should be well above normal, commonly at least 1.5 times the 50-day average. Heavy volume shows that the supply at the level was absorbed by real demand rather than briefly overrun.
What came before the breakout matters as much as the breakout day itself:
- A tight base. Ranges that contract and volume that dries up before the breakout show that sellers are running out. A wide, loose range breaks less cleanly.
- A well-defined level. Resistance tested at least twice is visible to everyone, so its break releases more orders.
- Trend alignment. A breakout in the direction of the higher-timeframe trend (lesson 1) has the larger flow behind it.
- Room to move. The next resistance should be far enough away to offer at least twice the risk.
- A supportive market. Breakouts fail more often when the broad market is correcting.
Retests
After many breakouts, price returns to test the level it broke, the role reversal described in lesson 2. A healthy retest pulls back on lighter volume, holds above the zone on a closing basis and turns up again. A retest that closes back inside the range is a warning that the breakout may be failing.
The choice between the two entries is a trade-off rather than a right answer. Buying the breakout guarantees participation but accepts more failures. Waiting for the retest improves the price and the reward-to-risk ratio but misses the breakouts that run straight away. A common compromise is to buy half the position on the breakout and half on a retest that holds.
Failed breakouts and traps
A failed breakout closes back inside the range soon after breaking out. The reversal tends to be fast for a structural reason. Traders who bought the breakout are now trapped, and most of them placed stops just below the level or below the range. As price falls back, those stops become sell orders, and short sellers who see the failure add to them. A failed move in one direction is often followed by a quick move to the opposite side of the range.
Warning signs that a breakout may fail:
- a close back inside the range within one to three sessions;
- a long upper wick on the breakout day and a weak close;
- volume at or below average;
- a breakout straight into resistance on the weekly chart;
- a breakout after a long, extended advance rather than from a fresh base;
- a weak broad market.
The same logic works in reverse below support: a break of support that quickly closes back inside the range traps sellers and often reverses upward. In the Wyckoff method, a false breakdown below a trading range in accumulation is called a spring, and a false breakout above a range in distribution an upthrust; lessons 6 and 7 cover both in detail.
Measured moves
A measured move projects a target from the pattern itself. For a rectangular range, add the range's height to the breakout level: a $40 to $45 range that breaks out at $45 projects to about $50. For a flag, the length of the pole before the flag is added to the breakout point.
Measured moves are rough guides. Use them to check that a trade offers enough reward before entering, and to plan partial exits, while trailing a stop on the rest of the position. If the nearest resistance on the weekly chart sits below the measured target, the nearer level is the more realistic objective.
How to apply it
| Rule | Breakout long | Failed breakout short |
|---|---|---|
| Setup | Tight base under resistance tested at least twice, trend aligned | Close above resistance, then a close back inside the range within one to three sessions |
| Entry | Breakout close passing all three tests, or a retest that holds | The close back inside the range, or a break of that candle's low |
| Stop | Back inside the range: below the level by about 0.5 to 1 ATR, or below the breakout candle's low | A few cents above the false breakout's high |
| Target | Measured move or the next major resistance; trail the remainder | The middle of the range first, then the range low |
| Invalidation | A daily close back inside the range | A new close above the false high |
Position size follows from the stop. Decide the amount of the account to risk on the trade, then divide it by the distance from entry to stop; see stop-loss and position sizing and risk-reward ratio.
Worked example (illustrative numbers). A stock has traded between $40.00 and $45.00 for seven weeks, and ATR is $1.20. It closes at $45.90 on 2.1 times average volume, near the top of a wide candle. The account is $50,000, and the trader risks 1%, or $500.
| Item | Value | Basis |
|---|---|---|
| Entry | $45.90 | Breakout close |
| Stop | $44.20 | Back inside the range, about 0.7 ATR below the level |
| Risk per share | $1.70 | $45.90 − $44.20 |
| Shares | 294 | $500 ÷ $1.70, rounded down |
| Target | $50.00 | Measured move: $45 + $5 |
The reward is $4.10 per share, about 2.4 times the risk, and the position is worth about $13,500. Now suppose a different outcome. The stock pokes to $45.80 and closes at $45.40, then the next day closes back at $44.40, inside the range, on heavy volume. A failed-breakout short at $44.40 with a stop at $45.95, just above the false high, risks $1.55. A target of $40.20, just above the range low, offers $4.20, about 2.7 times the risk. Short selling carries additional risks, including borrowing costs and gaps against the position; traders who only buy can use the mirror trade, a failed breakdown below support.
Common mistakes
- Buying intraday pokes. Many breakouts that look decisive at noon close back inside the range.
- Chasing extended moves. Buying far above the level puts the stop far away and the reward close. Some systems refuse entries more than a few percent above the breakout point.
- Ignoring volume. A breakout on light volume has not shown that demand overcame the supply at the level.
- Holding a failed breakout. Once price closes back inside the range, the reason for the trade is gone. Lowering the stop turns a small loss into a large one.
- Trading every breakout. In a choppy market, most breakouts fail; filter by trend and by the quality of the base.
- Forgetting scheduled events. An earnings gap can jump straight through a stop.
Breakouts in Clear Tape
The trading systems page includes several breakout presets. All of them are evaluated after the close on daily bars, so each one waits for a close beyond the level as this lesson recommends.
- 20-Day Breakout buys a close above the highest high of the previous 20 sessions, following Richard Donchian's four-week rule and the Turtle traders.
- 52-Week High Breakout buys the first close above the 52-week high on volume of at least 1.5 times the 50-session average. Its stop is the higher of the entry day's low and the entry minus two ATR(14), never more than 10% below the entry.
- Volume Base Breakout buys a close above the pivot of a five- to thirteen-week base no deeper than 15%, on volume of at least 1.4 times average, after a prior advance of at least 30%. The close must be no more than 5% above the pivot, and the target is +20%.
- NR7 / Inside-Day Breakout buys a close above the high of a narrow-range or inside day in an uptrend (lesson 3).
Each preset lists its full rules and the conditions in which it struggles, and the System view in the chart drawer draws its past signals on the daily chart. The drawer's technical analysis also detects chart patterns such as rectangles, triangles and flags, with a breakout level, a measured target and a status of forming or confirmed. Volume is not checked in that pattern detection, so apply the volume test from this lesson yourself. Building systems is free; backtests are available to Tools and Pro members.
Summary
- A valid breakout closes beyond the level, on a wide candle that closes near its extreme, on volume of at least 1.5 times average, ideally from a tight base and in the direction of the larger trend.
- Retests offer a better price but may not come; splitting the entry is a reasonable compromise.
- A close back inside the range turns a breakout into a trap, and the trapped traders' exits fuel a fast move the other way.
- Measured moves give rough targets; size every trade from the stop and require at least twice the risk in reward.
