Market Structure Basics: Highs and Lows

01 The four swing labels: HH, HL, LH, LL

Uptrends step up, downtrends step downAn uptrend is a chain of higher highs and higher lows. A downtrend is a chain of lower highs and lower lows.

An uptrend is a chain of higher highs (HH) and higher lows (HL). A downtrend is a chain of lower highs (LH) and lower lows (LL). Every structure call on this page comes from those four labels.

Uptrend. Each pullback low holds above the last low, and each push sets a higher high.

Downtrend. Each bounce stalls below the last high, and each drop sets a lower low.

Four labels describe every trend

HH (higher high), HL (higher low), LH (lower high), LL (lower low). An uptrend is a chain of HH and HL. A downtrend is a chain of LH and LL. Every pattern in this series is built from these four labels.

Dot the last three highs and three lows first

Before reading anything else on a chart, mark the last three swing highs and three swing lows. Both stepping up means long bias; both stepping down means short bias. That is the trend read, no indicator needed.

02 Which swings to mark, which to ignore

Mark only swings that produced a real moveA swing counts when price left it decisively. Wiggles inside chop are noise.

Mark a swing only if price made a clear move away from it before turning. Marking every wiggle produces a false structure break on every candle. Consistency beats precision here.

Only the circled swings count. The flat cluster on the left is chop. The chart turns on the circled swings, so those are the only ones to map.

A swing high is a candle whose high stands above the candles on both sides of it; a swing low is the mirror. That basic rule fires constantly, so add the filter: the swing counts only if price made a clear move away from it before turning. A high followed by a three-candle drift is noise. A high followed by a decisive leg down is structure.

How to mark a chart

Zoom out first. Set the timeframe you actually trade, then read structure one timeframe higher for context.
Mark only swings that produced a real move away from the level. Skip the wiggles inside a range.
Label each one HH, HL, LH or LL relative to the swing before it. The labels must form a chain.
Be consistent. The exact pixel does not matter, but mark the same type of swing every time.

Marking every pivot creates a false break every candle

Mark every micro pivot and a structure break appears on every candle, flipping your bias long and short into the chop. If your swing map changes meaning each bar, you are marking noise.

03 Pullback vs break of structure

A wick through the last higher low breaks the trendA dip that turns at a higher low is a pullback. A wick through the last higher low is a break of structure.

An uptrend stays intact while price keeps posting higher lows; every dip that holds is a pullback. The trend breaks when price closes decisively through the last significant higher low.

Break of structure (BOS). The last higher low held the uptrend together. Price trading below it is the first objective signal that the uptrend is over.

While price keeps posting higher lows, the uptrend is intact and every dip is a pullback. When a significant low is taken out, wick included, structure is broken: drop the long bias to neutral or short until a new chain of swings forms. The same logic runs in reverse for downtrends and a wick above the last lower high.

A higher low continues the trend; a wick through it ends it

Check one thing at every dip: did price turn at a higher low, or did it trade through the last higher low? The first is a pullback and the trend continues. The second is a break of structure.

Keep a horizontal line on the last higher low

Draw a horizontal line at the last significant higher low and leave it there. Closes above it keep the long bias. A close below it is the break. The line makes the call, not the trade's mood.

04 Thicken the trend line into a trend zone

Draw the trend as a zone, not a hairlineLine 1 follows the shallow edge of two pullbacks, line 2 runs parallel through their deepest wicks. Two touches draw it, a third confirms it.

Price rarely respects a single hairline, so thicken the trend line into a trend zone: a narrow band between the shallow edge of the pullbacks and their deepest wicks.

The trend zone holds pullbacks a single line misses. The band rides the higher lows, the parallel top marks where pushes stall, and the base range shows where the move began.

Two swing lows draw the line; a third touch confirms it. To build the zone, draw line 1 through the shallow edge of those two reactions, where the candle bodies turned, then draw line 2 parallel through their deepest wicks. The narrow band between the two lines is the trend zone. It absorbs the wicks that pierce a single line, and it gives the stop a concrete home: just past line 2.

Orders sit in a band, not on a line

Large orders are worked across a range of prices, not at one tick. A zone that spans the pullback bodies and their deepest wicks puts entries and invalidations where those orders sit, instead of where a thin line happened to fall.

A single line gets wicked and reclaimed on the same candle

A lone trend line gets pierced by a wick and reclaimed within a bar, shaking you out for nothing. Thicken it into the zone so a stop-run through line 1 does not read as a broken trend. A close beyond line 2 is what kills the trend.

05 Swing points as resting liquidity

Swing points hold the crowd's stop-lossesStops and breakout orders cluster at obvious highs and lows, and price gets pushed into them.

A swing high is a pool of liquidity: breakout buy orders rest on it and short stop-losses sit above it. Price gets pushed into that pool so large positions can fill, which is why obvious breaks so often start with a sweep.

Sweep, then break. Price spikes through the swing high to fill the stops resting above it, then reverses into the move down. The structure break started as a liquidity grab.

First attempts through obvious swing points often fail for this reason: the market pushes just past the level, fills the resting orders, triggers the stops, and only then trends the other way. Read structure as a map of where liquidity sits and a break of structure becomes predictable: the swing that broke was where the resting orders sat.

Stops cluster above equal highs, so the break gets sold

Stops and breakout orders pile up above clean equal highs, so that is the first place price gets pushed to fill them. Buying the obvious break often supplies the liquidity for the reversal.

Trade after the sweep resolves, not the piercing candle

When a swing point breaks, skip the candle that pierced it. Wait for the sweep to reject or for the level to be reclaimed, then trade the structure that forms after the liquidity is taken.

06 The whole method in six rules

Six rules cover trend, break, and liquidityThe swing labels, the significance filter, the break rule, the trend zone, and the sweep.

These six rules are the working vocabulary for every pattern in this series: ranges, wedges, and order blocks all build on this swing map.

The whole page in six lines

Uptrend is higher highs and higher lows. Downtrend is lower highs and lower lows.
Mark only significant swings, the ones that produced a real move. Ignore the wiggles.
A dip that makes a higher low is a pullback. A wick through the last higher low is a break of structure. Price taking out the swing point is the break; you do not wait for the candle to close.
Skip the single trend line. Thicken it into a trend zone: line 1 on the shallow edge of two pullbacks, line 2 through their deepest wicks.
Your swing points are liquidity: stops and breakout orders parked at the obvious price.
Structure breaks usually start with a sweep of that liquidity, so let the crowd get run first.

Trends step their swings; reversals sweep them first

Price trends by stepping its swings in one direction, and it flips by sweeping the liquidity at those swings before it breaks them. Every pattern in the rest of this series is a variation on that read.
