Descending triangle: define support and check both breakout directions
A descending triangle has roughly horizontal support below successively lower highs. It is conventionally interpreted as bearish, but price can break above the descending boundary instead of below support.
This page supplies no reproducible recognition test or trading success rate. A 0–100 confidence field is a model assessment, not an accuracy measurement.
AI Detection
Use AI Chart Analysis as a second review
Pineify can help interpret a chart screenshot. Its response may miss context or misread a level, so compare it with your own chart annotations.
Prepare a readable chart
Include the symbol, timeframe and relevant swings. A screenshot can omit price history needed to assess the setup.
Review the structure
Pineify reviews a submitted image using a general vision model. It does not implement a fixed two-low/three-high touch classifier or guarantee a measured-move target. Check the pattern text and any reported levels against the actual chart.
Check the interpretation
Compare the response with the chart. Verify each price level yourself and record confirmation and invalidation rules before considering a trade.
How to Detect It
Step-by-Step Detection Guide
Work through the chart in order. Treat each condition as a check, and record why a setup fails as well as why it qualifies.
Record both boundaries
Mark comparable lows and declining highs with prices and bar positions. State a pivot rule and its right-side confirmation delay.
Fix tolerance and confirmation
Choose support tolerance and a closed-bar breakout condition before reviewing later data. Record an upside break as well as a downside confirmation.
Compare the screenshot response
Use an eligible signed-in account and a readable image. Check prices and uncertainties; do not infer unavailable volume or labels.
Geometry is not a specialized detection pipeline
The conventional structure needs at least two comparable lows and two declining reaction highs. Requiring a third high is a possible study choice, not a universal definition or an implemented Pineify threshold. A descending triangle can be a continuation candidate in a downtrend or a reversal candidate after an advance.
A falling wedge differs because both boundaries fall and converge. For convergence, the upper boundary falls faster than the lower boundary. A flat lower boundary is the distinguishing triangle feature.
Work through a hypothetical descending triangle
Set horizontal support S = 100 with tolerance 0.50. Recorded lows of 100.00, 100.20 and 99.80 are all within 99.50–100.50. Let upper-boundary highs be 110 at bar 4, 106 at bar 12 and 102 at bar 20. The line is R(b) = 110 − 0.5 × (b − 4), reaching 100 at bar 24. Assume the omitted neighboring bars satisfy the selected pivot rule.
If pivots use two bars on each side, the last high is known at bar 22. At that bar R(22) = 101. A custom completed close below 99.50 before bar 24 confirms downward; a close of 99 passes while exactly 99.50 does not. These are demonstration rules and prices, not current data or optimized settings.
Calculate projections and reject contrary outcomes
Using the initial upper boundary of 110 and support of 100 gives a height of 10. A projection anchored at the 100 support reference is 100 − 10 = 90. A close at 99 is a confirmation observation, not the same anchor; using it would instead project 89. State the anchor rather than silently changing it.
At bar 22, an alternative close above R(22) + 0.50 = 101.50 rejects the bearish candidate. A close at 102 therefore represents upside failure. Under this exercise, an unresolved candidate expires at the bar 24 intersection. Neither a confirmed break nor a measured target promises a continued move.
Separate image quality from a performance claim
Keep the full candidate, axes, timeframe and any volume used in the rule visible. Pineify may misread a boundary, return another pattern description or leave a price unknown. There is no validated universal four-indicator limit, best timeframe, crypto accuracy percentage or confidence cutoff here.
If evaluating the pattern, retain failures and negative examples. Score agreement with prewritten geometry separately from subsequent returns and trading costs.
