Descending Triangle

The descending triangle is one of the most recognizable bearish continuation patterns in technical analysis. It forms when price repeatedly tests a flat horizontal support level while making progressively lower highs, creating a descending resistance trendline that compresses price into a narrowing range. This pattern signals that sellers are becoming more aggressive with each rally attempt, while buyers defend a fixed level with diminishing strength. The descending triangle is the mirror image of the ascending triangle and appears most reliably on daily and hourly charts across equities, futures, and forex.

How to Identify the Descending Triangle

1. Flat horizontal support — Identify a price level where the asset has bounced at least twice, forming a clear floor. Each touch should occur within a tight range (within 0.5% of the same price). The more touches, the more significant the level — but also the weaker it becomes with each test.

2. Descending resistance trendline — Connect two or more lower highs that form after each bounce off support. The trendline should slope downward at a consistent angle. Each rally fails at a lower price than the previous one, showing sellers stepping in earlier.

3. Declining volume during formation — As price compresses between support and the descending trendline, volume should contract. This reflects decreasing participation and a coiling effect. A pattern with rising volume during consolidation is less reliable.

4. Narrowing price range — The distance between support and each successive lower high shrinks over time. The pattern typically resolves when price has been squeezed into the final 25-30% of the triangle’s width. At this point, a decisive move is imminent.

Volume is the critical confirmation tool. A valid descending triangle shows declining volume during formation and a sharp volume increase on the breakdown candle.

Entry Rules

1. Breakdown close below support — Enter a short position when a candle closes below horizontal support with volume at least 1.5x the 20-bar average. A wick below support that closes back inside the triangle does not count as a valid breakdown.

2. Confirmation signal — For higher-probability entries, wait for a second consecutive close below support or a retest of the broken support level from below. The retest entry offers a tighter stop and better risk-to-reward but occurs in roughly 50-60% of breakdowns.

3. Filter low-quality breaks — Avoid entries when the breakdown occurs on below-average volume, during illiquid trading hours, or when the broader market is moving sharply in the opposite direction. Context matters — a descending triangle breaking down into a strong market-wide rally is lower probability.

Exit Rules & Targets

1. Primary target — Use the measured move technique: subtract the triangle’s height from the breakdown point. This gives the minimum expected move and is reached in approximately 60-65% of valid breakdowns.

2. Secondary target — Identify the next significant support level on a higher timeframe chart. If the measured move target aligns with a higher-timeframe support zone, consider taking partial profits there.

3. Trailing stop — Once price moves 1R in your favor (where R equals the distance from entry to initial stop), move your stop to the most recent lower high or the broken support level, whichever is closer to current price.

4. Time-based exit — If the trade has not reached 50% of the measured move target within a timeframe equal to half the pattern’s formation duration, consider reducing position size. Stalling breakdowns frequently reverse.

Target Calculation: Measure the vertical distance from horizontal support to the first (highest) high of the triangle. If support is at $100 and the first high is at $112, the triangle height is $12. Subtract $12 from the breakdown point ($100) to get a minimum target of $88.

Stop Loss Placement

Place the stop above the most recent lower high within the triangle formation. This is the last point where selling pressure overwhelmed buyers, and a close above it signals the pattern has failed. For example, if the last lower high before breakdown was $105, set the stop at $105.50-$106.00 to allow for minor noise. This placement typically yields a risk-to-reward ratio of 2:1 to 3:1 when targeting the full measured move. Avoid placing stops above the very first high of the triangle — this creates an unnecessarily wide stop that destroys the trade’s R:R profile.

Practical Example

On the daily chart of MSFT, a descending triangle forms over 5 weeks during a broader market pullback. Price establishes horizontal support at $390, bouncing off this level three times. Meanwhile, rally attempts create lower highs at $412, $405, and $399, forming a clear descending trendline. Volume declines steadily from 35 million shares per day to 18 million during the consolidation.

On day 26, MSFT closes at $387.50 — below the $390 support — on volume of 42 million shares (2.3x the 20-bar average of 18 million). The triangle height is $22 ($412 minus $390). Subtracting $22 from the $390 breakdown point gives a target of $368.

A trader with a $25,000 account risks 2% ($500) per trade. With a stop at $399.50 (above the last lower high) and entry at $387.50, the risk per share is $12.00. Position size: 41 shares ($500 / $12.00). The measured move target at $368 represents $19.50 per share profit, or $799.50 — a 1.6:1 reward-to-risk ratio. MSFT reaches the $368 target 11 trading days after the breakdown.

Best Timeframes for the Descending Triangle

The descending triangle performs best on the daily chart, where the 64-68% breakdown success rate is most consistently documented. Patterns forming over 3-8 weeks on the daily timeframe give the clearest signals because they reflect genuine shifts in supply and demand rather than intraday noise.

On the 1-hour chart, the pattern is useful for swing traders looking for 2-5 day holds, though success rates drop slightly due to increased noise. The 15-minute timeframe works for day traders, particularly on high-liquidity names like SPY and AAPL, where the pattern can form and resolve within a single session. Weekly chart triangles are the most powerful but rare — when they break down, the moves tend to be substantial and sustained.

Common Mistakes

1. Entering before confirmation — Many traders short at support anticipating the breakdown instead of waiting for a decisive close below. Support exists because buyers defend it, and premature entries get stopped out on bounces. Wait for the close below support with volume confirmation.

2. Ignoring volume on the breakdown — A breakdown on declining or average volume is a trap more often than not. Price dips below support, triggers stops, then reverses sharply back into the triangle. Require volume expansion of at least 1.5x the recent average before committing.

3. Miscalculating the measured move — The triangle height should be measured from the widest point (first high to horizontal support), not from a mid-pattern swing high. Using a shorter measurement underestimates the target and causes premature exits.

4. Ignoring the broader trend — Descending triangles are continuation patterns and work best within an existing downtrend. A descending triangle forming after a sustained uptrend may resolve as a reversal, but the odds are less favorable and the pattern may break upward instead.

5. Overtrading failed patterns — If a descending triangle breaks upward, do not immediately look for another short entry. An upside resolution often signals a trend change. Step aside and reassess.

How to Journal Descending Triangle Trades

Journal Field	What to Record	Why It Matters
Pattern Type	Descending Triangle	Filter and review all triangle trades separately
Setup Quality	Rate 1-5 based on clarity of support and trendline	Correlate quality ratings with win rates over time
Support Touches	Number of times price tested horizontal support	More touches may weaken support — track if 2-touch vs 4-touch patterns perform differently
Volume Confirmation	Breakdown volume as multiple of 20-bar average	Establish your minimum volume threshold based on results
Entry Method	Initial break vs. retest entry	Determine which approach yields better R:R for your style
Measured Move Accuracy	Target price vs. actual low reached	Calibrate whether full or partial measured moves are more realistic
Market Context	Trend direction on higher timeframe	Track whether your triangle trades work better with-trend or counter-trend

After tracking 50 or more descending triangle trades, patterns in your data will reveal which variations produce the best results. You may find that 3-touch support triangles on the daily chart with 2x volume breakdowns are your highest-probability setup, while intraday triangles underperform. JournalPlus’s tagging system lets you filter by pattern type, setup quality, and timeframe to surface these insights without manual spreadsheet work. Use the notes field to capture the visual quality of each triangle — the data alone does not tell the full story.
