Price stalls at the same level two or three times, each dip ends a little higher than the last, and the breakout looks only a candle away. A trader buys just under that ceiling, price turns down from it once more, and the stop-loss is hit before the move ever starts.
This guide shows how to confirm that the ascending triangle pattern is really there, where to enter after the breakout, where the stop-loss goes and how to measure the target. It then works one trade through in pips and money and explains what to do when the pattern breaks down instead.
An ascending triangle is a chart pattern formed by a flat resistance line across the highs and a rising trendline under the lows. It shows buyers paying higher prices on each dip while sellers hold one level. It usually breaks upwards, and Thomas Bulkowski's study of more than 1,400 patterns found upward breakouts about 63% of the time.

An ascending triangle is a price pattern in which a horizontal resistance line and a rising support line converge, as buyers lift each low while sellers keep capping the highs at one price.
Inside an uptrend it is usually read as a bullish continuation pattern: the market pauses, the sellers at the ceiling are absorbed, and the trend resumes once price closes above it. When the same shape appears at the end of a downtrend, it can act as a reversal pattern instead, marking the point where buyers start to take control.
It is one of three triangle patterns, together with the descending triangle and the symmetrical triangle. The next section compares the three side by side.
A resistance level is a price at which selling has repeatedly stopped a rise, so the market has turned lower from it more than once.

Triangle pattern trading means trading three related shapes with the same tools, a trendline entry, a stop beyond the opposite line and a measured target, while each shape leans in a different direction.
The table sets out how the three triangles differ in shape, bias and trade plan.
| Pattern | Shape | Usual bias | Entry trigger | Stop-loss | Target |
|---|---|---|---|---|---|
| Ascending triangle | Flat top, rising lows | Bullish | Close above resistance | Below last higher low | Height added to breakout |
| Descending triangle | Flat bottom, falling highs | Bearish | Close below support | Above last lower high | Height subtracted from breakout |
| Symmetrical triangle | Falling highs, rising lows | Follows prior trend | Close outside either line | Inside opposite line | Widest part projected from breakout |
When both lines are flat, the pattern is no longer a triangle but a rectangle, which is traded as a range until price closes outside it.
An ascending triangle is built from three groups of parts, and all three need to be present before the shape counts as the pattern.
The flat resistance line is the upper boundary, where sellers keep defending one price. Three touches carry more weight than two, because each extra rejection shows the same sellers are still there.
The rising support line is the lower boundary, drawn through the higher lows, where buyers pay more on each dip.
The two lines squeeze price into a smaller range as they head towards the apex, the point where they would meet. Spot forex has no central volume figure, so traders read tick volume from their platform as a stand-in.
Tick volume is the number of price updates recorded in a candle, used in forex as a stand-in for traded volume because the market has no central exchange.
Analysing an ascending triangle runs in four checks that separate a real pattern from a random range. Each check has to pass before moving on to the next.
The highs need to stop at roughly the same price at least twice. On most forex charts, small overshoots of a few pips still count as the same level, as long as candles close back below it.
At least two higher lows are needed to draw the lower line. Price should also move between the two lines several times, so the triangle is filled with trading rather than drawn from two isolated points.
Tick volume usually fades while the pattern forms. Bulkowski found that breakouts arrive on average about 64% of the way from the start of the pattern to the apex, so a breakout very close to the apex is a weaker signal.
The pattern is only confirmed when a candle closes above the resistance line on the chosen timeframe. Wicks above the line are often pulled back inside, so the close is the trigger.

An ascending triangle is usually bullish, and Bulkowski found upward breakouts in about 63% of patterns. It turns bearish when price closes below the rising trendline.
The shape leans bullish because sellers keep offering at the same price, so the highs stay flat, while buyers step in earlier on each dip, so the lows rise. Each test of resistance removes some of the sellers waiting there, and the ceiling gets thinner every time.
The trend before the pattern changes how it is read. The table shows the four situations traders meet most often.
| Market context | Usual reading | What confirms it |
|---|---|---|
| Inside an uptrend | Bullish continuation | Candle close above resistance |
| At the end of a downtrend | Possible bullish reversal | Close above resistance and a break of the last lower high |
| Close below the rising trendline | Bearish breakdown | Candle close below the trendline |
| Breakout very close to the apex | Weak signal either way | A second candle close or a retest |
The bias is only a lean, so traders still wait for the candle close before acting.
A close below the rising trendline cancels the bullish case. Bulkowski found this downward breakout in roughly 37% of patterns, with a much higher failure rate than upward breakouts, at 38% against 17%.
Whichever way price breaks, the trader needs a fixed entry, stop-loss and target before acting, which is what the next section sets out.
Three practical strategies cover the breakout: entering on a close above resistance or on a retest, placing the stop-loss below the last higher low, and aiming for a target equal to the height of the triangle added to the breakout level.
Choose one of two entries before the breakout happens, and stick to it.
Bulkowski found that price came back to test the broken level in about 64% of upward breakouts. That is why the retest entry is common, and also why it misses roughly a third of the moves.
Place the stop-loss a few pips below the most recent higher low. A close back below the rising trendline means the pattern has failed, so the stop sits where the trade idea stops being valid. The distance to the stop then decides the lot size, not the other way round.
Measure the height of the triangle from the resistance line down to the first low of the pattern, then add it to the breakout level. Bulkowski found that about 70% of upward breakouts reached this target.
Some traders take half the position off at the target and trail the stop on the rest, so part of the profit is banked while the remainder can follow a longer move.

The trade below runs one ascending triangle on the EUR/USD 4-hour chart from first touch to final result. The prices are illustrative and are not historical quotes or trading advice.
EUR/USD rises into 1.0950 three times and turns lower each time. The pullbacks end at 1.0850, 1.0880 and 1.0905, so the lows are rising. The height of the triangle is 1.0950 − 1.0850 = 100 pips.
A 4-hour candle closes at 1.0962, above resistance, and the trader buys at that close. The stop-loss goes at 1.0900, 5 pips below the last higher low, which is 62 pips from the entry. The target is the breakout level plus the height: 1.0950 + 100 pips = 1.1050, which is 88 pips above the entry.
The account holds £10,000 and risks 1%, or £100, per trade. One standard lot of EUR/USD is worth $10 per pip, which is £8 at an illustrative GBP/USD rate of 1.2500. The lot size is £100 ÷ (62 × £8) = 0.20 lots, so one pip is worth £1.60.
Money at risk is 62 × £1.60 = £99.20. Money at target is 88 × £1.60 = £140.80. The risk-to-reward ratio is 88 ÷ 62 = 1:1.42. A spread of 1 pip takes 1.6% of the stop distance.
| Item | Value |
|---|---|
| Resistance level | 1.0950 |
| Triangle height | 100 pips |
| Entry price | 1.0962 |
| Stop-loss | 1.0900 (62 pips) |
| Target | 1.1050 (88 pips) |
| Lot size | 0.20 lots (£1.60 per pip) |
| Money at risk | £99.20 |
| Money at target | £140.80 |
| Risk-to-reward | 1:1.42 |
In the first outcome, two candles after the breakout, price dips back to 1.0952, where the old resistance now holds as support. Buyers step in, and over the following sessions EUR/USD reaches 1.1050. The target order closes the trade for a gain of 88 pips, or £140.80.
In the second outcome, the next candle closes back inside the triangle at 1.0935, and price slides through the rising trendline to 1.0900. The stop-loss closes the trade for a loss of 62 pips, or £99.20, which is the 1% planned at entry. The trader treats the pattern as failed, does not add to the position and does not reverse straight away into a short without a separate signal.

The ascending triangle can work well for UK forex traders because it gives a clear entry, stop-loss and target. It also fails often enough that confirmation and a stop-loss are essential on every trade.
The figures below come from Thomas Bulkowski's study of more than 1,400 ascending triangles in bull markets.
| Measure | Upward breakout | Downward breakout |
|---|---|---|
| Share of breakouts | 63% | 37% |
| Break-even failure rate | 17% | 38% |
| Reached measured target | 70% | 44% |
| Throwback or pullback | 64% | 63% |
These are results from a large sample of US share charts, not from forex, so traders should test the pattern on their own pairs and timeframes before relying on the figures.
On spot forex, a UK retail trader reads tick volume instead of exchange volume, so volume only supports the reading. The spread matters more on small triangles: a 1-pip spread is 1.6% of a 62-pip stop but 6.7% of a 15-pip stop on a 15-minute chart. Breakouts on the major pairs are also more likely to follow through during the London and New York sessions, when liquidity is highest.
At least two highs at the same level and two higher lows are needed to draw it. A third touch of resistance makes the level more reliable.
Measure the distance from the resistance line to the first low of the pattern and add it to the breakout level. A 100-pip triangle breaking out at 1.0950 gives a target of 1.1050.
The bullish setup is cancelled, and any long position should be closed at the stop-loss. A short trade needs its own confirmation, because downward breakouts from this pattern fail more often.
In Bulkowski's study, 63% of ascending triangles broke upwards and 70% of those upward breakouts reached the measured target. These figures come from US shares, so they should be tested on forex pairs before being relied on.
Yes, the pattern appears on 15-minute and 1-hour charts. False breakouts are more frequent there, and the spread takes a larger share of a small triangle's height.
The ascending triangle has a flat top and leans bullish. The symmetrical triangle has two sloping lines and usually breaks in the direction of the trend before it.
An ascending triangle combines a flat ceiling with rising lows, and it leans bullish because buyers keep paying more while sellers hold one price. It is confirmed by a candle close above resistance, traded with a stop below the last higher low and a target equal to the triangle height, and cancelled by a close below the rising trendline. Bulkowski's figures show it breaks upwards more often than not, but they come from US shares.
Count at least three touches of resistance, wait for the close, size the position from the stop distance and set the target before entering. Exit without hesitation when price closes back below the trendline. An ascending triangle is best treated as a trade plan with a defined exit, not as a promise that the breakout will come.
