ICT Market Structure — Read Trend, BOS and MSS on NQ

Quick answer

Market structure in ICT is the sequence of swing highs and swing lows. Higher highs with higher lows is an uptrend; lower lows with lower highs is a downtrend. A body close through the last swing in the trend direction is a break of structure (continuation), while a close against the trend after a liquidity sweep is a market structure shift (reversal). Everything else — FVGs, order blocks, entries — is read inside that skeleton.

Swing points come first

A swing high is a candle with lower highs either side of it; a swing low is a candle with higher lows either side. Mark only the swings that are obvious at a glance — if you have to squint, the market will not respect it either.

The four structural states

State	What the chart shows	What to do
Bullish	Higher highs and higher lows	Buy pullbacks into discount
Bearish	Lower lows and lower highs	Sell rallies into premium
Consolidation	Equal highs and lows, no clean sequence	Wait — mark the range edges as liquidity
Transition	Sweep of an extreme then a counter-trend close	Treat as a possible reversal (MSS)

Break of structure vs market structure shift

The two events read almost identically on the chart, and telling them apart is the whole skill:

Break of structure (BoS) — a close through the last swing with the trend. Continuation. Trade the pullback.
Market structure shift (MSS) — a close through the last opposing swing against the trend, right after a liquidity sweep. Reversal. Trade the FVG it left.

Top-down: which timeframe owns the structure

Daily / 4-hour — the bias. Which direction is the higher-timeframe draw on liquidity?
15-minute — the dealing range and premium / discount split.
5-minute — the working structure you actually track during the session.
1-minute — the entry only. Never set bias here; 1-minute structure breaks constantly.

How to mark structure on NQ, step by step

Open the 15-minute and mark the last two obvious swing highs and swing lows.
Label the state — bullish, bearish or consolidating.
Mark the liquidity that state implies: prior day high and low, session highs and lows, equal highs.
Drop to the 5-minute and track each new swing as it forms; note every BoS.
When price sweeps a marked level and closes against the trend on the 1-minute, mark it as a possible MSS and look for the FVG.

Common mistakes

Marking every wiggle. Too many swings turns any move into a "break". Keep only the obvious ones.
Changing timeframe mid-trade. If the 5-minute is your structure, a 1-minute break is not a reason to exit.
Calling reversals without a sweep. A counter-trend close that took no liquidity is usually just a deeper pullback.

Practise structure reading

In NQ Replay, load a session, hide every indicator, and mark structure bar by bar on the 5-minute. Log each BoS and each MSS. Twenty sessions of this does more for execution than any new setup, because every entry model in ICT assumes you have the structure right first.

Frequently asked questions

What is market structure in ICT trading?

It is the sequence of swing highs and swing lows that defines trend: higher highs and higher lows for bullish, lower lows and lower highs for bearish, with breaks of that sequence marking continuation or reversal.

What is the ICT market model?

Set higher-timeframe bias, mark the liquidity pools, wait for a Killzone, let price sweep the stops, confirm a market structure shift, then enter on the Fair Value Gap and target the opposite pool.

How do I identify swing highs and lows?

A swing high has lower highs on both sides; a swing low has higher lows on both sides. Only mark the ones that are obvious without zooming — those are the levels other traders' stops sit against.

What is the difference between BOS and MSS?

A BOS is a close through the last swing in the direction of the trend and confirms continuation. An MSS is a close against the trend after a liquidity sweep and confirms reversal.

Which timeframe should I use for market structure?

Use the daily and 4-hour for bias, the 15-minute for the dealing range, the 5-minute as your working structure, and the 1-minute only to refine entries.

How do I practise reading market structure?

Replay historical NQ sessions bar by bar with indicators off, marking swings, breaks of structure and shifts as they form, and log the outcome of each so recognition becomes automatic.
