Field	Type	Description
`pattern_pivot_timestamps`	array	Array of all internal pivot timestamps making up the triangle structure.
`pattern_pivot_prices`	array	Array of all internal pivot body-snapped prices making up the triangle structure.
`resistance_level`	number[]	The price level of the horizontal flat top resistance.
`resistance_right_timestamp`	number[]	Timestamp denoting where the resistance line extends to on the right.
`support_left_timestamp`	number[]	Unix timestamp of the ascending support line start anchor (L1).
`support_left_price`	number[]	Price level of the ascending support line start anchor (L1).
`support_right_timestamp`	number[]	Timestamp denoting where the support line extends to on the right.
`support_right_price`	number[]	The price level of the support line at the right endpoint.
`breakout_occurred`	boolean[]	Boolean flag (true/false) indicating if price successfully broke above the resistance.
`is_confirmed`	boolean[]	Explicit boolean flag (true/false) indicating if the Ascending Triangle pattern is fully confirmed (synonymous with breakout_occurred).
`breakout_timestamp`	array	Unix timestamp of the candle that triggered the confirmation breakout.
`breakout_price`	array	The closing price of the candle that triggered the confirmation breakout.
`breakout_resistance_price`	array	The specific price of the resistance line at the exact moment of the breakout (same as resistance_level).
`projection_price`	array	The theoretical upside price target calculated by adding the pattern's initial height to the breakout resistance price.
`direction`	string[]	The inherent bias of the pattern. Always 'bullish' for an Ascending Triangle.
`status`	string[]	The current state of the pattern: 'forming', 'confirmed', or 'invalidated'.
`status_reason`	string[]	Context detailing why the pattern holds its current status (e.g. 'awaiting_breakout').
`pattern_index`	number[]	A sequential integer index uniquely identifying this specific pattern instance.
`timestamp`	integer[]	Unix time of each candle, in seconds

What is Ascending Triangle?

An Ascending Triangle has a flat resistance level and rising support, which suggests buyers are growing more aggressive. The endpoint returns its pivots, both boundaries and a projected target.

Ascending Triangle formula

Output	Calculation
Target	Resistance + height of the triangle

How to read Ascending Triangle in your code

Signal	Meaning	Condition
Forming or confirmed	Detection status	`status` and `is_confirmed`
Breakout	Price closed above resistance	`breakout_occurred` is true
Target	Measured-move projection	`projection_price`

Limitations: Geometric pattern detection depends on pivot settings, so tune deviationATR and depth or lookback values on your own market. A confirmed pattern is not a guaranteed move. Nothing on this page is financial advice.

Results are JSON.

Is the latest Ascending Triangle value final?

No. The newest value belongs to the candle still forming and can change until it closes. Add backtrack=1 to read the last closed candle.

Which Ascending Triangle settings can I change?

You can set lookback, lookforward, deviationATR, deviationType, source, heikinashi. See the parameters table above for defaults.

Can I get Ascending Triangle for US stocks?

Yes. Use exchange=stocks with a ticker such as AAPL. US stocks are included on the Pro plan and above.
