Why some levels matter more than others
Open any trading forum and you will find charts covered in lines. A line on its own means little. A level only matters if orders rest behind it — because orders, not opinions, are what move price. The entire discipline of reading liquidity levels comes down to one question: where did other traders put their stops?
The answer is surprisingly predictable. Traders anchor their risk to what they can see, and the same things are visible to all of them: yesterday's extremes, last week's high, the low of the Asian session, a round number. Those shared reference points become liquidity pools — shelves of stop-losses and breakout orders — the volume a large order needs to fill against, which is why this framework treats them as targets.
The complete map of resting orders
1. Previous day high and low (PDH / PDL)
Levels every intraday trader can see. Intraday strategies reference them, and they are an obvious place for the stop of an overnight position. In this framework, price approaching PDH is not approaching "resistance" — it is approaching a pool of orders. The reaction after the level is taken is what the framework reads, after the close. This is the raid that powers the classic liquidity sweep.
2. Previous week and month extremes
Higher-timeframe pools are read the same way, on a larger scale. A weekly high taken during a London session with immediate rejection is one of the reversal contexts this framework weighs most heavily. Map them as a hierarchy: monthly > weekly > daily. Our guide to institutional highs and lows covers this hierarchy in depth.
3. Equal highs and equal lows
When two swing points sit at nearly the same price, retail traders read a "double top" and place stops above it — this framework reads a pool that has doubled in size. Equal extremes concentrate stops at almost the same price, which is why this framework treats them as targets rather than as support or resistance.
4. Session ranges
The Asia range is the reference for London; the London range is the reference for New York. The high and low of each completed session are short-term pools that the next session can raid first — the mechanism behind the Judas swing.
5. The 50% equilibrium
The midpoint of yesterday's range divides the day into premium and discount. It is not a stop cluster, but it is a reference: after a sweep, price can travel back to equilibrium before continuing. Treat it as a first target rather than an entry level.
6. The Midnight Open
The New York 00:00 open is the institutional reference for the whole day. Price above it is trading at premium, below at discount. It deserves its own study — see the Midnight Open pivot.
Key takeaways
- A level matters only if orders rest behind it — visibility creates liquidity.
- PDH/PDL, weekly and monthly extremes, equal highs/lows and session ranges are the core pools.
- Equilibrium (50%) and the Midnight Open are references, not stop clusters.
- Levels are targets for raids first, support/resistance second.
Using the map: from levels to trades
Knowing the map changes your default behaviour at a level. Instead of buying the breakout of PDH, you expect the raid; instead of panicking when your "support" breaks, you watch for the close back inside and the displacement that signals a sweep. The map tells you where; confirmation — a fair value gap plus an order block context — tells you whether.
Draw the levels every day, at the same time, the same way. Or automate them: consistency is the entire point. A liquidity map is only as useful as it is complete: a missing level is a level you cannot plan around.
What this article does not do
- No prediction. A setup that meets every condition described here can fail.
- Weak contexts. Around session opens, scheduled releases and thin hours, levels can be traded through and fills can be worse than planned.
- No recommendation. Nothing here is an instruction to trade a specific instrument or level.
