How to Identify Swing Highs and Swing Lows

Every concept in Smart Money trading starts with swing points. Market structure? Based on swings. Order blocks? Form at swing-based structure breaks. Liquidity? Clusters above swing highs and below swing lows.

If you identify swings wrong, everything downstream is wrong. Here's how to get it right.

What Is a Swing High?

A swing high is a candle whose high is higher than the highs of the candles on both sides of it. It represents a local peak - price went up, reached this point, and then turned back down.

Simple definition: The candle with the highest high, with lower highs before and after it.

What Is a Swing Low?

A swing low is a candle whose low is lower than the lows of the candles on both sides of it. It represents a local trough - price went down, reached this point, and then turned back up.

Simple definition: The candle with the lowest low, with higher lows before and after it.

How Many Candles Should Define Swing Sensitivity?

The key variable in swing detection is sensitivity - how many candles on each side you require to confirm a swing.

Low Sensitivity (1-2 candles)

• Detects many swing points
• Captures minor fluctuations
• More structure events (more BoS, more ChoCh)
• Good for: Scalping, very short-term trading
• Risk: Lots of noise, many insignificant swings

Medium Sensitivity (3-5 candles)

• Balanced detection
• Captures meaningful swing points while filtering minor noise
• Good for: Day trading, most intraday strategies
• Recommended starting point for most traders

High Sensitivity (7-10+ candles)

• Detects only major swing points
• Fewer but more significant structure events
• Good for: Swing trading, position trading
• Risk: May miss valid intermediate structure

How to Choose

Match your sensitivity to your trading timeframe and style:

Trading Style	Timeframe	Suggested Sensitivity
Scalping	1m-5m	2-3 candles
Day trading	15m-1H	3-5 candles
Swing trading	4H-Daily	5-8 candles
Position trading	Daily-Weekly	8-12 candles

Once you choose a sensitivity, stick with it. Changing sensitivity mid-analysis creates inconsistent structure readings.

Should You Use Close-Based or High/Low-Based Swings?

Two methods for detecting swings:

High/Low-Based (Wick)

Uses the candle's high and low (including wicks) to determine swing points. The wick extremes define the swing.

Pros: Captures the true price extreme. Wider swing identification. Cons: Wicks can be noisy - a long wick might be a liquidity sweep, not a genuine swing.

Close-Based (Body)

Uses the candle's open and close (body only) to determine swing points. Ignores wicks.

Pros: Filters out wick noise. More conservative swing identification. Cons: Misses extreme price points. Narrower swing identification.

Which to Use?

Many traders use high/low-based for swing identification but close-based for structure breaks:

• Swings are defined by the wicks (true extremes)
• But a structure break requires a candle to close beyond the swing (confirmed break)

This combination captures the full swing range while requiring conviction for structural events.

What Swing Identification Mistakes Should You Avoid?

Mistake 1: Inconsistent Sensitivity

Using 3-candle sensitivity for one swing and 5-candle for the next. This creates an inconsistent structure picture where some swings are "more confirmed" than others.

Fix: Pick one sensitivity and apply it uniformly.

Mistake 2: Seeing Swings That Aren't There

In a strong trend, every minor pullback can look like a swing. But a 2-candle pause in a 20-candle rally isn't a meaningful swing low - it's noise.

Fix: Use appropriate sensitivity. In strong trends, increase sensitivity to only capture significant pullbacks.

Mistake 3: Missing Obvious Swings

The flip side - using such high sensitivity that you miss clear, important swing points.

Fix: If a swing point is visible to the naked eye and significant (price moved meaningfully from it), your sensitivity should capture it. Adjust if you're missing obvious points.

Mistake 4: Counting Wicks as Structure Breaks

A candle wicks beyond a swing high but closes below it. Is the swing broken? If you're using close-based structure breaks - no. The wick is likely a liquidity sweep, not a genuine break.

Fix: Require a candle close beyond the swing for structural events.

Mistake 5: Not Using the Same Method Everywhere

Defining swings one way on the 4H chart and differently on the 15m chart creates conflicting structure readings.

Fix: Use the same detection method across timeframes. Only the sensitivity should change (higher sensitivity on higher timeframes).

Can You Automate Swing Detection?

Manual swing identification is straightforward on a clean chart but becomes difficult when:

• You're monitoring multiple timeframes
• The chart is busy with other analysis
• You need consistent detection across sessions
• You want to track structure in real-time

Indicators that automate swing detection:

• Apply consistent sensitivity rules every time
• Mark swing points as they form
• Update structure labels (BoS, ChoCh) automatically
• Work across all timeframes with adjustable sensitivity

The key advantage: consistency. An indicator like Reversal Market Structure applies the same rules to every candle, eliminating the human tendency to see what you want to see.

The Short Version

• Swing highs and lows are candles with higher/lower extremes than surrounding candles
• Sensitivity (candle count) determines how many swings you detect - match it to your style
• Close-based vs. wick-based detection serves different purposes - use both strategically
• Consistency is everything - pick your settings and apply them uniformly
• Swings are the building blocks of market structure, which underpins all SMC concepts
• Automated detection ensures consistent application that manual identification can't match
