Understanding the OANDA order book tool: see where traders are placing orders, predict stop hunts, identify liquidity zones, and trade with institutional reads — not retail candles
Master the OANDA order book to see where traders are placing orders, predict stop hunts, identify liquidity zones, and trade with institutional reads. The free browser tool that turns every chart into an auction — and the five reads that turn the bars into entries.

Every candle is an auction — and the OANDA order book shows who's bidding
Every candle is the result of an auction. Buyers and sellers meet at a price, the orders get filled, and the chart records what happened. The candle shows the result. The order book shows the auction itself: the resting limit orders waiting above and below price, the visible depth the market is advertising, and the total depth the market is hiding. A retail trader sees a candle and asks "what happened?" An order flow trader sees the same candle and asks "what were the orders doing before, during, and after?" The OANDA order book is the free browser tool that gives retail traders the second answer — and it's the tool that turns the same chart into a fundamentally different trade.
This page covers the five reads that turn the OANDA order book from a chart decoration into an actual trading edge: reading supply and demand zones with order confirmation, spotting stop hunts before they fire, tracking trapped traders on the position book, reading visible vs total depth for level conviction, and aligning orders with psychological levels for high-probability entries. Each one has its own chart signature, its own setup rules, and its own common mistakes. The page ends with a comparison table and the five mistakes that turn the bars into noise.
If you've opened the OANDA order book but didn't know what the bars meant, or you've heard about order flow but didn't know where to start, this is the page that maps the territory. Same tool, cleaner read, better trades.
How to use this page
New to the OANDA order book? Start with the supply/demand section — it's the most accessible read and the one that translates directly into entries. Already using the order book but the bars feel noisy? Skip to the stop hunt section — the read that separates the trades that work from the trades that fake out.

The tool in plain English
What the OANDA order book actually is — and why most retail traders misunderstand it
The OANDA order book is a free browser-based tool inside OANDA Labs that shows the resting limit orders above and below the current price on any forex pair OANDA offers. Each horizontal bar represents how much size is waiting at that price — the longer and thicker the bar, the more orders are clustered at that level. The bars are split into two layers: visible depth (the orders displayed in the tool's window) and total depth (the orders across the broader OANDA client base). Every order on the book is a participant telling the market what they want to do when price arrives. The order book is what they're offering. The candle is what price actually does. Reading both at the same time is the order flow edge.
Orders aligned with the psychological level. The OANDA order book bars are stacking at the round-number level — every retail trader who has ever placed a buy limit at the obvious level has added to the cluster. The order book makes the level visible before price arrives, and the visible depth tells you how much size is waiting. When price reaches the level, the orders are the fuel for the rejection. The full read on how to align order book bars with horizontal levels, the way to read visible vs total depth at the cluster, and the entry trigger that turns a psychological level with order confirmation into a high-probability setup is in the OANDA order book guide.
Three things turn the OANDA order book from a chart decoration into a trading edge:
Read the bars at the level, not at the price. The bars above and below the current price are the orders waiting for price to arrive. The bars at a key horizontal level are the orders that matter — they're the participants defending the level or waiting to fade a move into it. Read the bars at the level, and the supply/demand zone becomes visible before price arrives.
Watch for sudden order disappearance. When a thick cluster at a key level suddenly thins out or disappears, the supply/demand zone has lost its defender. The level is no longer being defended, and the next test is more likely to break through. The disappearance is the signal that the level has been invalidated.
Stack the read with the position book. The order book shows what the market wants to do when price arrives. The position book shows what the market is already holding. Together they tell the full story: the orders waiting at the level, plus the underwater traders who will be forced to close when price returns. Both reads together are the institutional read.
Core idea
The OANDA order book turns every chart into an auction — and the read is the same logic as a horizontal level, but with the participant count attached. A supply zone with thick order book depth is the same level you've always traded, but you now know how many orders are defending it. The level is the same. The conviction behind it is visible.
Who this page is built for
Three different traders, one shared read upgrade
The OANDA order book isn't a new pattern to learn — most traders have heard of order flow and many have opened the tool once. What's missing is the framework that turns the bars into entries. This page is built to work whether you've never opened the order book, you've tried it but couldn't translate the bars, or you already use it and want a stacking framework that turns the same setups into consistent trades.
Beginner
"I've opened the OANDA order book but I don't know what the bars mean."
You don't need a paid platform. You need a read. The five reads section below gives you a starting point for every bar pattern — supply zones, stop hunts, trapped traders, depth conviction, and psychological levels. Each read is mechanical, no guessing required once you know the rules.
Intermediate
"I see the bars but I can't tell which ones actually mean something."
Almost certainly the data is right and the read is wrong. The mistake section below covers the five reads that turn the bars into noise — Asian session reads, single-candle imbalances, old position book clusters, ignoring the higher timeframe, and forcing entries ahead of news. The bars don't change. The interpretation does.
Advanced
"I use the order book daily. I want a stacking framework that combines all five reads."
Skip to the comparison table — each read has its own chart signature, best timeframe, and stop placement. The table maps all five reads in one place so you can stack them for the highest-conviction setups.
The five order book reads
The five reads that earn their place on the chart
Each read shows a different layer of the auction. Pick the one that matches what you see on the chart — or use the deep-dive cards below to read each one in detail.
Supply & demand zones: turning horizontal levels into conviction reads
Every supply and demand zone you've ever traded was a horizontal level with the participant count hidden. The OANDA order book makes the participant count visible — and that single change doubles the conviction behind every level you draw. A supply zone with thick order book bars above the level is a ceiling with the seller count attached. A demand zone with thick bars below the level is a floor with the buyer count attached. The level is the same level you've always traded. The order book is the read that tells you whether the participants are actually defending it.
A 1-hour supply zone with order book buildup. The orange bars on the left show a thick cluster of sell limit orders sitting at the supply zone — the same level that has rejected price twice and is now waiting for the third test. The order book bars make the supply zone visible before price arrives. When price returns, the resting orders are the fuel for the rejection. The full read on confirming supply and demand zones with the order book — including the right way to read the bars, the difference between a single test and a stacked test, and the entry trigger that doubles your win rate — is in the S/D confirmation guide.
The two supply/demand reads that matter most are the stacked test and the order disappearance. A stacked test is when the order book bars at the level stay thick across multiple candle tests — the participants are still defending. The level is high conviction. An order disappearance is when the bars thin out or disappear between tests — the participants have withdrawn, and the level is no longer defended. The level is invalidated, and the next test is more likely to break through.
Thick bars at the level + visible stacking across tests = defended zone. The supply or demand zone is being held by the participants on the book. The level is high conviction. Trade the next test with the level defence as the invalidation read.
Bars thinning or disappearing between tests = invalidated zone. The participants have withdrawn. The level is no longer defended. The next test is more likely to break through. Don't trade it as a supply/demand zone — let the level break, then trade the retest as new structure.
Bars stacking at a level ahead of the first test = high-conviction zone. When the bars are thick at a level before price has even arrived, the participants are pre-positioning. The first test usually respects the level; the second or third test is where the highest-probability entry lives.
Bars appearing at a level only after the test = weak zone. When the bars show up at a level only after price has already rejected, the orders are reactive, not pre-positioned. The level is weaker than a pre-positioned cluster. Treat the read with less conviction.
S/D rule
Trade the level with the order book confirmation, not the level alone. A supply zone with thick, stacking order book bars is a high-conviction short setup. The same zone without the bars is a coin flip dressed up as a setup. The order book is the read that separates the two.

Stop hunts: predicting where the liquidity grab is going to fire
A stop hunt is what happens when price moves through an obvious level — the round number, the recent swing high, the obvious support or resistance — to fill the stop-loss orders clustered just beyond it. The orders are sitting there because every retail trader who has ever placed a stop "just beyond the obvious level" has added to the cluster. When price arrives, the stops get filled, the orders become market orders in the opposite direction, and price reverses. The move looks random on the chart — a wick through the obvious level followed by a sharp reversal. The order book shows the orders that caused it. The stop hunt isn't a mystery. It's a predictable liquidity grab, and the OANDA order book is the read that predicts it.
The stop hunt in real time. Price dips below the obvious support level, the resting buy stops get filled (visible as the order book bars thinning at the level), and the filled orders become sell market orders that drive price sharply lower before reversing. The same setup without the order book looks like a random wick through the level. With the order book, you saw the orders waiting, the fill happening, and the reversal that followed. The full read on predicting stop hunts with the order book — including the levels where they cluster, the news-driven stop runs, and the entry trigger that turns the post-hunt reversal into a high-probability trade — is in the stop hunt trading guide.
Stop hunts follow three predictable patterns. The round-number hunt happens at obvious levels like 1.1000, 1.1450, or 1.1800 — the levels every retail trader watches. The swing-level hunt happens at recent highs and lows that retail traders use as stop placement. The news-driven hunt happens 5-15 minutes before high-impact releases when the institutional positioning for the release becomes visible. Each pattern has a different timing signature, but all three share the same setup: thick orders just beyond the obvious level, a price move into the orders, and a sharp reversal once the orders are filled.
The full stop-run signature. Price moves toward the obvious level, the order book bars thin as the orders get filled, the candle prints a wick through the level, and the reversal begins. The full stop-run analysis is the read that turns a confusing price move into a predictable liquidity event. The right entry is on the first candle after the orders are filled — not on the wick itself.
The four stop hunt rules
1
Identify the obvious level before price arrives
The level has to be one retail traders actually watch — a round number, a recent swing high, an obvious horizontal. The orders cluster at the level because retail traders put them there. Read the chart for the level first, then look at the order book for the orders.
2
Confirm the orders are sitting beyond the level
Thick order book bars just beyond the obvious level — not at the level, just beyond it. The orders are the stops. The level is where price has to move to fill them. The orders being "just beyond" is the confirmation the hunt is being set up.
3
Wait for the fill — don't anticipate the reversal
The entry is after the orders are filled, not before. The candle that prints the wick through the level is the fill candle. The next candle is the entry candle. Don't try to catch the wick — wait for the orders to actually fill and the reversal to begin.
4
Enter on the first candle after the reversal begins
The first candle after the orders fill and the reversal begins is the entry trigger. The stop is the wick extreme. The target is the level the orders were sitting beyond — the level price returned to after the fill.
Watch out
Not every wick through a level is a stop hunt. Sometimes price breaks through the level cleanly because the participants at the level have withdrawn. The order book is the filter — if the bars at the level disappear before the wick, the level was invalidated, not hunted. No orders at the level = no stop hunt. The wick is just a wick.

Trapped traders: reading the position book to see who's underwater
The OANDA position book shows the open positions held by OANDA clients — long or short, at each entry price. The bars are colour-coded: pink/red bars are trapped shorts (positions currently losing, waiting for price to return to entry to exit at breakeven), blue/green bars are trapped longs (same idea, opposite side). The position book tells you where the underwater participants are sitting — and where they'll be forced to close if price returns. A cluster of trapped shorts at 1.1650 is a buy-zone waiting to happen, because once price returns, every short needs to buy to close, and that buying pressure is the fuel for the bounce.
The trapped shorts cluster. The pink/red bars on the left are the open short positions sitting below current price — every one of them is waiting for price to return to their entry so they can close at breakeven. When price returns to the zone, the trapped shorts are forced to buy back what they sold at a worse price. That buying pressure is the fuel for the bounce. The full read on reading the position book, the difference between trapped longs and trapped shorts, and the entry trigger that turns a fresh cluster into a high-probability reversal trade is in the OANDA liquidity positioning guide.
The position book read has one critical filter: freshness. A cluster of trapped shorts that formed in the last 24-48 hours has the most underwater traders still waiting. A cluster that has been sitting for two weeks has absorbed some of the closing flow already — the underwater traders have either given up on the return or have manually closed at a worse price. Fresh clusters are the highest-probability reversal zones because the underwater traders are still waiting, and their closing flow is still available to fuel the bounce.
The mixed cluster read. When the position book shows both trapped longs and trapped shorts at multiple levels, the picture is more complex — and the read is that price is ranging between the two clusters. The trade becomes the return to whichever cluster has the freshest signature, with the other cluster as the target. The right entry is on the freshest cluster; the wrong entry is forcing a direction when both clusters are equal.
Trapped trader rule
Fresh clusters beat old clusters every time. A trapped shorts zone that formed yesterday has underwater traders still waiting. The same zone two weeks later has fewer traders waiting and less closing fuel. Trade the freshest cluster you can find — and ignore the old ones, no matter how thick they look.

Visible vs total depth: reading the conviction behind the bars
Every order book bar in the OANDA tool represents two numbers — the visible depth (orders displayed in the tool's window) and the total depth (orders across the broader OANDA client base). The visible depth is what the market is offering. The total depth is what the market is hiding. Most retail traders watch only the visible depth because it's the bars on the screen. The institutional read is in the total depth — because total depth is the real liquidity, the orders that are actually there whether the market advertises them or not.
A level with high total depth and low visible depth is the strongest supply/demand zone on the chart. The orders are there — the market just isn't advertising them. When price arrives at the level, the orders are the fuel for the rejection. A level with high visible depth and low total depth is the opposite — the market is showing the orders but the real liquidity isn't there. When price arrives, the orders get pulled, the level breaks, and the visible depth was a fake.
High total depth + low visible depth = quiet conviction. The orders are real but the market isn't advertising them. The level is the strongest read on the chart. Trade the next test with high conviction.
High visible depth + low total depth = loud fake. The market is showing the orders but the real liquidity isn't there. The level is the weakest read on the chart. The orders will get pulled and the level will break.
Total depth growing while visible depth stays flat = pre-positioning. The orders are accumulating at the level but the market isn't moving the bars. The next test has the strongest possible defence — pre-positioned liquidity that the market is hiding.
Both depths shrinking = level invalidated. The participants at the level are withdrawing. The next test is more likely to break. Don't trade it as a supply/demand zone.
Depth rule
The quiet levels are the strongest levels. The loud levels with thick visible depth bars are usually fakes. The quiet levels with high total depth and low visible depth are where the real participants are hiding. Read the depth numbers, not just the bars.

Psychological levels: where the order book makes the obvious level obvious
Round numbers like 1.1450, 1.1800, and 1.1000 are the levels every retail trader watches — and the levels where the OANDA order book always shows the most depth. Every retail trader who has ever placed a buy limit at the round number, a stop just beyond it, or a sell entry on a rejection has added to the cluster. The result is that round-number levels have the most orders on the book of any level on the chart. The orders cluster because retail traders cluster there. The OANDA order book makes that clustering visible before price arrives.
The round-number order cluster. The bars stacking at the obvious psychological level are the orders placed by every retail trader watching the same level. The order book makes the level visible before price arrives, and the depth tells you how many orders are waiting. The full read on aligning order book bars with psychological levels — including the round numbers that matter most, the entry trigger that turns the cluster into a setup, and the trades where the read has the highest probability — is in the 3 insights guide.
The psychological level read has a nuance that most retail traders miss. The orders cluster at the round number, but the most actionable read is the orders sitting just beyond the round number — the stops being placed beyond the obvious level. When those orders are thick, the round number is the level where the stop hunt will fire. When the orders at the round number itself are thick, the level is being defended. Both reads are useful. The first is the stop hunt setup; the second is the supply/demand setup. The OANDA order book shows both.
The deepest read
Every retail trader watches the same levels. The order book shows what they're doing at those levels. Round numbers, swing highs, obvious support and resistance — these are the levels every retail trader has on the chart. The orders at those levels are the orders retail traders have placed. The OANDA order book makes the participant count visible. Trade the levels you've always traded — but now you know who's there.

Common mistakes
Five mistakes that turn the order book into noise
The OANDA order book is precise data, but it's also easy to misread. The five mistakes below are about reading the bars in the wrong context — not about the bars themselves.
Reading the order book during Asian session
The order book during Asian hours is dominated by limit orders from retail traders who set them and walked away. The depth looks high but the conviction is low — the orders get pulled or filled on the slightest tick. Read the order book during London and NY, when the participants are active and the orders reflect real intent.
Treating every thick bar as a defended level
Thick bars appear at every obvious level. Most of them get pulled before price arrives. The defended level is the one where the bars stay thick across multiple tests — and where the participants are actually responding when price arrives. The read is the stacking, not the bars themselves.
Ignoring the higher-timeframe trend
A supply zone with thick order book bars inside an H4 uptrend is the level to fade — the higher-timeframe direction will eventually break through. The same zone inside an H4 downtrend is the level to defend. The order book is the same; the read depends on the higher timeframe.
Forcing entries ahead of high-impact news
The order book 5 minutes before NFP, FOMC, or central-bank decisions is not a tradeable signal — it's the institutional positioning for the release, which will be wiped out the moment the data prints. Read the order book before the release as a position-sizing input. Wait for the release to clear before trading the next level.
Trading the order book without the position book
The order book shows what the market wants to do when price arrives. The position book shows what the market is already holding. Together they tell the full story. Without the position book, the trader is reading only half the auction — and missing the trapped traders that make the highest-probability reversal setups.
FAQ
FAQ — quick answers about the OANDA order book
What is the OANDA order book?
The OANDA order book is a free browser-based tool inside OANDA Labs that shows the resting limit orders above and below the current price on any forex pair OANDA offers. Each horizontal bar represents how much size is waiting at that price — the longer and thicker the bar, the more orders are clustered at that level. The bars are split into visible depth (the orders displayed in the tool's window) and total depth (the orders across the broader OANDA client base). The full walkthrough is in the OANDA order book guide.
Is the OANDA order book free?
Yes — the OANDA order book and position book are both free with any OANDA account. They run in the browser inside OANDA Labs, no extra software required, and the data is real-time.
How does the order book help confirm supply and demand zones?
The order book bars at the zone tell you how many orders are defending the level. Thick bars that stay stacked across multiple candle tests = defended zone. Bars that thin or disappear between tests = invalidated zone. Trading the level with the order book confirmation doubles the conviction behind every S/D entry. The full read is in the S/D confirmation guide.
Can I predict stop hunts with the OANDA order book?
Yes — the orders sitting just beyond obvious levels (round numbers, swing highs, key support/resistance) are the stops being placed by retail traders. When the orders are thick and price moves toward them, the stop hunt is being set up. The entry is on the first candle after the orders are filled and price reverses. The full read on trading stop hunts profitably is in the stop hunt trading guide.
What does the order book tell us about how traders trade?
Three insights come from watching the bars consistently: (1) retail traders cluster their orders at obvious psychological levels — round numbers, swing highs, recent support/resistance; (2) the orders at those levels are usually limit orders that get pulled before price arrives, leaving the level defended in name only; (3) the orders that survive multiple tests are the ones with real participants behind them, and those are the levels worth trading. The full three insights are in the 3 insights guide.
What's the difference between the order book and the position book?
The order book shows the resting limit orders — what the market wants to do when price arrives. The position book shows the open positions held by OANDA clients — what the market is already holding. The order book is the auction's offer. The position book is the auction's inventory. Together they tell the full story of who is doing what at every level.
Do I need a paid platform to use order flow tools?
No — the OANDA order book and position book are free and provide the most important retail-accessible order flow data. Paid platforms add per-candle footprint, heatmaps, and stacked imbalance reads, but the foundational read (where the resting orders and trapped positions are) is free. Start with the free tools. Add the paid platforms when you know which reads you actually need.
Which read should I start with?
The supply/demand confirmation read — it's the most accessible translation of order book bars into entries you've already been making. The level is the level you've always traded. The order book is the conviction attached to it. Once that read makes sense, add the stop hunt read, then the position book for trapped traders, then depth conviction for filtering the real levels from the loud fakes.
Quick glossary
Key terms used on this page
The OANDA order book has its own vocabulary. If a term below doesn't ring a bell, it's probably defined here.
Order Book
The live list of resting limit orders above and below the current price. Each bar represents how much size is waiting at that level. Thick bars = strong supply/demand. The free version is the OANDA order book inside OANDA Labs.
Position Book
The live map of open positions held by OANDA clients. Pink/red bars are trapped shorts; blue/green bars are trapped longs. Fresh clusters are the highest-probability reversal zones because the underwater traders are still waiting to close.
Visible Depth
The orders displayed in the OANDA order book tool's window. This is what the market is offering. Often the loudest part of the book — and often the least reliable because orders can be pulled without execution.
Total Depth
The orders across the broader OANDA client base. The real liquidity at the level — even if the market isn't advertising it. High total depth with low visible depth is the strongest conviction read on the chart.
Stop Hunt
A price move through an obvious level to fill the stop-loss orders clustered just beyond it. The filled orders become market orders in the opposite direction, fueling the reversal. Predictable when you read the order book before price arrives.
Trapped Traders
Open positions that are currently losing. Trapped shorts want price to return to their entry to exit at breakeven; trapped longs want the same. When price returns to a cluster of trapped positions, the closing flow creates the directional move.
Psychological Level
A round number or obvious level (1.1450, 1.1800, 1.1000) that every retail trader watches. Orders cluster at these levels because retail traders put them there. The OANDA order book makes the clustering visible before price arrives.
Stacked Test
When the order book bars at a level stay thick across multiple candle tests. The participants are still defending. The level is high conviction — and the highest-probability read for an S/D entry.
Final thoughts
If you only take three things from this page, take these
First: every candle is an auction — and the OANDA order book shows who's bidding. The candle shows the result. The order book shows the orders waiting above and below the price. The level is the level you've always traded. The order book is the participant count attached to it.
Second: the five reads stack into a single framework. S/D confirmation, stop hunt prediction, trapped trader positioning, depth conviction, and psychological level alignment — each one is a different layer of the same auction. Trade the level with all five reads aligned, and the conviction behind the entry is institutional-grade.
Third: the OANDA order book is free — the read is paid for in screen time. The tool is free, browser-based, and available to any OANDA account. The read is a learnable skill, but only by staring at the bars for hours, watching how they move before and after the candle prints, and seeing which signatures matter and which are noise.
One last thing
The OANDA order book turns every retail chart into an institutional read. The candles are the same candles you've always traded. The levels are the same levels. The only difference is that you now know who's defending them. That knowledge, applied with discipline, is the read that separates the trades that work from the trades that fake out.
