Aroon
Measures how recently a lookback's highest high and lowest low occurred.
Start with the input, not the story.
Recency of new extremes rather than the size of price change.
The precomputed 0–100 panel follows how recently price made a new high or low, first through consolidation and then into a new high. Platforms can handle repeated equal extremes differently.
Equal highs or lows and very short lookbacks can make the lines jump around. Compare the result with a simple Donchian rule.How traders commonly use Aroon
Aroon can label emerging directional conditions or consolidation, then be compared with a simpler price-extreme rule.
Measure how recently the lookback's highest high and lowest low occurred.
Keep this job separate from entry timing, stop placement and position size.
A useful counterexample
Repeated equal highs or lows and short lookbacks can make line crosses unstable without a meaningful price break.
Aroon for recency, Donchian for the actual level, ATR for width
Each part has a different job. If two tools answer the same question, remove one and compare the result.
Measures the recency of completed-bar extremes.
Shows the actual breakout boundary.
Measures channel width and breakout scale.
Follow the same order every time
- Freeze the Aroon and Donchian lookbacks.
- Resolve how equal highs and lows are treated before replay begins.
- After each candle closes, record Aroon state and price position separately.
- Measure Donchian width in ATR units.
- Compare the Aroon-filtered rule with the Donchian-only baseline.
The indicator is one part of the method
These strategy pages show the market conditions, entry, stop and exit around the indicator.
Donchian breakout
A rules-first breakout framework based on new lookback extremes.
- ENTRY
- Enter at the next H4 open after a completed close above the prior 20-bar upper channel for a long or below the lower channel for a short.
- STOP
- Initial stop is 2.0 × ATR(20) from the actual fill. Size to risk 0.50% of equity, rounded down to 0.01 lot; never add to or widen the position.
- EXIT
- Exit at the next H4 open after a completed close through the opposite 10-bar channel. The initial 2 ATR stop remains active until that exit.
Turtle-style breakout
An educational adaptation of channel breakout and volatility sizing principles.
- ENTRY
- Enter one unit at the next daily open after the qualifying channel close; there is no previous-winner skip rule.
- STOP
- Stop exactly 2N from actual fill. One unit risks 0.50% equity and is rounded down to 0.01 lot.
- EXIT
- Exit at next daily open after a completed close through the opposite 20-day channel; the 2N stop remains active.
Weekly swing breakout
Tests slow breakouts above or below pre-existing weekly structure.
- ENTRY
- Enter at Monday 00:00 UTC after the qualifying Friday close, provided the opening gap is no greater than 0.50 × weekly ATR.
- STOP
- Stop 0.25 × weekly ATR beyond the breakout candle's opposite extreme. Risk 0.35% equity and round down to 0.01 lot.
- EXIT
- Exit at the Monday open following the first weekly close through the most recent confirmed opposite-side swing; initial stop remains active.

Plain-language formula
The same indicator can look slightly different across platforms because the price input, smoothing and rounding may change. Note your settings before comparing two charts.
Where it may help
Trend emergence and consolidation research.
Where it struggles
Short lookbacks and assets repeatedly touching the same extreme.
What to pair it with
Pair it with something that answers a different question, such as volatility or market direction. Try the indicator on its own before adding more tools.
The shortcut to avoid
Interpreting a cross without controlling the prior regime.
