Have you ever wondered how the big players seem to move the
market and leave little invisible footprints that later pull price back like a
magnet. You see a strong impulse. Price rockets. Then later it comes back to a
zone and suddenly everything makes sense. That’s what we’re gonna dig into
right now. You’re gonna learn what the Price Action Volumetric Order Blocks
indicator actually does, why it matters for Trading, how to read its signals,
and how to start using it as a beginner while still getting a deep, practical
understanding of the inner mechanics.
This article walks you through the script itself, explains every major function and variable, and shows how the indicator links Order Blocks, Fair Value Gaps, volume, and classic institutional flow concepts — in plain American English, like we’re sitting across a coffee table and sketching charts. You’ll get screenshots-level descriptions, tables that summarize the mechanics, and practical guidance you can test on your charts right away.
Before we start, note that the Pine Script I used for this deep dive is the file you uploaded. I analyzed it directly and used it as the backbone for this explanation. If you want to inspect the script yourself, it’s available here.

What this indicator does for you in plain terms
If you’re new, keep this idea in your head. The indicator tries to find where institutions likely placed big orders. It does this two ways at once.
It draws order blocks — those last candles before a strong move — and marks them visually on the chart so you can see probable buy or sell zones.
It finds Fair Value Gaps — quick, three-candle imbalances where price skipped trading, leaving zones that price might revisit.
It also writes volume and internal buy/sell activity into the order block box, giving you an added layer: volumetric context that hints whether smart money was actually active there.
All together, the indicator is trying to give you the institutional footprint. When price revisits these zones, you can watch for confirmations and trade with better odds. This is central to many modern price action and Smart Money Concept approaches.

Why institutional flow and these tools matter for Trading
When you trade, the market isn’t only made of small retail orders. Institutions move huge orders and sometimes shove price quickly. That quick shove makes structural footprints like order blocks and fair value gaps. If you ignore them, you may be trading in a vacuum. If you learn to recognize and use them, you’re aligning with bigger liquidity flow and often get better entries and stops.
Many guides and trading educators emphasize that FVGs are imbalance zones that act as magnets; order blocks are origin zones of major moves. When both align, you get higher probability setups. That’s why the script combines both ideas and layers volume inside the blocks. It’s not just a visual — it’s a hypothesis of where liquidity and institutional activity happened.

Breaking down the script — top-level structure
The Pine Script file you uploaded is modular and includes several main parts. I’ll simplify them and explain in human terms.
Main sections you’ll see in the code
Fair Value Gap detection — simple three-candle detection with noise reduction and optional removal of mitigated gaps
Volumetric Order Blocks engine — the main block detection code that finds pivot points and constructs OB boxes with volume metrics
Alerts and visuals — alert conditions for formation, mitigation, and inside tests; drawing boxes, lines, and labels
ZigZag and pattern detection — a zigzag pivot detector used to detect structure and project targets with pattern detection for things like AB=CD or harmonic triangles
Misc utilities — helpers for label sizes, overlap pruning, and metric calculation
You don’t need to know every single function to use the
indicator, but seeing the high-level partition helps you trust the logic. The
script is careful about cleaning up drawn objects on the last bar and uses
arrays to manage box life cycles. It also exposes many inputs so you can tune
sensitivity, length, mitigation method, display options, and more. The input
defaults are thoughtful — offering you balance between noise and signal.
Fair Value Gap detection logic — what it does and why
Look at the top of the script. The FVG code compares three
candles. It measures the candle length against a moving average of candle
lengths (noise reduction) and then checks whether the third candle leaves a gap
from the first candle's range according to the usual three-candle FVG rule.
Key configurable pieces from the script:
Noise reduction length and noise reduction factor. These
prevent small, meaningless imbalances from cluttering the chart.
Remove mitigated FVGs toggle. This controls whether
previously filled (mitigated) FVGs are automatically removed from the chart.
Volume label displayed in the box so you can quickly see the
volume at the time the FVG formed.
Why they added noise reduction. If you paint every small FVG
on a 5-minute chart, the chart becomes useless. The code compares the current
gap to a moving average of gaps, and only marks the ones that pass a threshold.
That’s practice a lot of educators recommend: only mark meaningful imbalances.

Volumetric Order Blocks engine — the heart of the indicator
This is where it gets interesting. The script uses a pivot
detection and constructs order block objects with several metric fields:
top and bottom of each block
avg for mid price
vol representing the volume at the pivot candle
dir the candle direction (bullish / bearish)
blPOS and brPOS counters used to map internal buy/sell
activity across the lifetime of the block
xlocbl and xlocbr coordinates that are updated as bars pass
The engine identifies pivots using a pivot function
ta.pivothigh or ta.pivotlow depending on the configuration and then builds
blocks around the pivot candle according to your "Construction" mode
— either using a short "Length" anchored range with ATR adjustments
or using the entire candle body with "Full" mode.
Important configurable things you should note:
Length input determines pivot lookback
Mitigation method lets you choose whether a block is
considered mitigated when price touches the wick (Wick), the close (Close), or
crosses the average (Avg)
Show internal buy & sell activity toggles the display of
volumetric split boxes inside the block showing where buying vs selling took
place inside the block zone
Overlap removal cleans older blocks when they overlap with
the most recent block so the chart remains readable
All of this means the script is not just drawing rectangles.
It’s tracking their life, updating their right edge so the box extends in real
time, and calculating internal volumetric splits. That’s what “volumetric”
implies here: the indicator gives you a sense of where the volume was
concentrated inside the origin candle, and also tracks how price interacts with
the block over time.
This approach is powerful because many traders only mark
blocks and ignore the real trading volume signals inside the block. The script
helps you see whether the block had significant volume at formation, and
whether later price action inside the block looks like legitimate mitigation,
or a passing wick that didn’t reach the block average.
EBC Financial Group
ZigZag, projections and pattern detection — more than just
boxes
The latter part of the script includes a ZigZag-style pivot
detection (percent or ATR-based) and a fairly elaborate pattern detector that
tries to identify harmonic triangles, taps, AB=CD, Bat, Butterfly, Crab, Shark,
and other harmonic patterns. It uses price and time ratios, derives projected
target windows using Fibonacci-like multipliers, and draws projection boxes and
midlines.
Why this matters to you as a beginner who wants depth. These
tools help put the order blocks and FVGs into market context. An isolated order
block has lower value than an order block that aligns with a pivot-based target
projection or a harmonic pattern. The script attempts to give you this
confluence automatically so you can see:
whether an OB formed around a structural pivot
whether the projected target based on the zigzag aligns with
your OB or FVG
whether common harmonic patterns are present that
historically often coincide with institutional activity
This is basically a “confluence engine” that combines
structure, order blocks, imbalances, volume, and pattern projections in one
overlay. Use this to prioritize setups. If the projection, OB, and FVG all
stack, that’s a stronger case than only a single signal.

How the indicator detects and handles mitigation
Mitigation means price came back and "took" the
imbalance or block. The script offers three mitigation methods:
Close — checks if candle closes inside or beyond the block
edge.
Wick — checks if any wick pierced the block boundary.
Avg — checks if price crossed the block average.
Why does this matter. Some traders accept wick touches as
mitigation. Others only accept close-based mitigation because wick wicks can be
liquidity hunts or false tests. The script gives you the choice. If a block is
mitigated, the indicator can optionally remove that box or flag it as
mitigated. Many educators state that once a block is mitigated and price moves
away, that block loses predictive power. That’s the logic the indicator uses.
Alchemy Markets
Volume inside blocks — what the script shows and why it
helps
This is the volumetric twist. The script stores the pivot
candle's volume and prints it in the block. It also has a visual internal split
where the top half and bottom half of the block can be shaded differently to
reflect "buy" and "sell" activity inside the block.
Why that’s useful for you.
If a bullish order block was formed with low volume, that
signals a possible weak institutional entry that might not hold.
If a bullish order block formed with high volume, it
suggests a heavier institutional commitment.
If internal buy/sell shading shows the origin candle had
more selling than buying despite being a "bullish" origin, that’s a
red flag — maybe the block isn’t a true accumulation zone.
Bottom line. Volume context helps avoid false positives.
Many modern Smart Money traders combine OB/FVG detection with volume to avoid
bad trades. The script gives you that exact combo.

How to read the visual output on your chart
When you add the script to TradingView, expect to see:
Boxes for FVGs and Volumetric Order Blocks, colored for
bullish vs bearish.
Labels showing volume and sometimes percentage splits inside
OBs.
Dashed mid-lines that mark the block average and can act as
decision zones.
Alerts for "OB Formed", "OB Mitigated",
"Price inside OB", and similar signals.
A beginner-friendly reading method:
If price is far away from an OB, treat it as a "zone to
watch" — no action yet.
When price returns to the OB and shows a rejection candle
(pin, engulf, sharp rejection), consider the OB to be validating and prepare
for a trade if other rules align.
If the OB has been mitigated (by your chosen method),
deprioritize it.
Use volume label as a filter — prefer OBs with higher
formation volume.
That’s a simple playbook you can memorize and practice.
EBC Financial Group
Simple beginner rules you can start using immediately
Below is a set of plain English trading rules you can test.
Treat them as a learning scaffold, not gospel.
Only trade OBs on higher timeframes for learning. Start with
one-hour or four-hour charts until you get the hang of it. FVGs and OBs are
more meaningful on HTFs.
EBC Financial Group
Look for confluence. Favor OBs that overlap with FVGs, pivot
projections from the ZigZag, or a nearby structural level.
Use the mitigation method that fits your strategy. Beginners
often prefer "Close" mitigation because wick hunts can be noisy.
Confirm with price action. Wait for a clear rejection before
entering. Examples: bullish engulf, hammer, or quick wick rejection.
Place stop just outside the block. Use ATR sizing if price
structure is noisy.
Size small and practice. Risk a tiny percent of your capital
until you prove the approach on a demo.
These are short, concrete practices that keep you safe while
learning volumetric OB trading.

signals all at once will confuse you.
Example trade workflow using the indicator
Here’s a simple workflow you can demo on a demo account:
Scan: On daily or four-hour, scan for unmitigated Volumetric
OBs that align with FVGs.
Mark confluence: If OB and FVG overlap and the ZigZag
projection sits nearby, mark as higher-probability.
Wait for intraday pullback: On lower timeframe, wait for
price to enter the OB zone.
Confirm: Look for price action confirmation — rejection
candle or structure flip.
Execute: Enter with stop outside block. Consider partial
scaling out at first target and trailing rest.
Manage risk: Risk small percent of account, use ATR as
sizing guide.
This workflow helps you transform the indicator’s visuals
into real practice without overtrading.
Limitations and common pitfalls
No indicator is a silver bullet. Expect these issues:
Over marking on low timeframes: If you enable FVGs at low
TFs with low noise reduction, the chart floods with gaps and false signals. Use
filters.
trenddaytrader.com
Volume is contextual: A high-volume pivot on a low-liquidity
asset still may be weak. Always cross-check with the market context and time of
day.
EBC Financial Group
Wick touches vs closes: Wicks can be liquidity hunts. If you
trade on wick touches only, you get stopped out a lot. Many pros prefer
close-based mitigation.
Alchemy Markets
Pattern detectors produce false positives: The ZigZag
pattern detection will sometimes label normal structure as harmonic. Treat
pattern outputs as hints, not confirmations.
trenddaytrader.com
Backtest and forward paper test: An indicator can look great
visually but fail on a real account. Always backtest cross-asset and forward
test in simulation.
These risks are typical for OB/FVG strategies. The script
mitigates some by offering noise thresholds and mitigation choices, but user
discipline matters most.
EBC Financial Group
Quick guide to inputs and recommended beginner settings
The script exposes many input options. Here are
beginner-friendly suggestions you can try and refine over time.
OB Length: keep conservative. A value like five (the
default) is okay for one-hour charts. Increase for higher timeframe.
FVG Noise Reduction Length: use a moderate window, such as
sixty, if you're on intraday. That reduces false small gaps.
Noise Reduction Factor: set to three default if you want
fewer FVGs.
Mitigation Method: set to "Close" until you
understand wick hunts.
Show Activity: on. Internal volume shading helps learning.
Overlap: on. Keeps chart readable.
Show metrics: on. Labels help you see which OBs had real
volume.
Make one change at a time and track results.
How to verify the indicator’s outputs against price history
(a basic manual backtest)
You don’t need fancy code to verify. Here’s a short manual
backtest plan:
Pick an asset: major forex pair or large-cap stock.
Timeframe: start with four-hour or daily.
Window: inspect the last one hundred OBs/FVGs visually. Mark
whether price returned and got rejected, filled and then reversed, or ignored
the zone.
Record: make a simple spreadsheet with date, OB type, volume
at formation, mitigation state, outcome (win/loss), and why.
Measure: compute win-rate and average R:R. Also measure how
many OBs were mitigated before being revisited.
This manual approach reveals what the indicator actually
produces on the market you trade. Many pros do this with a dozen setups before
automating.

Example of reading a real chart setup (text walkthrough)
You see a bullish Volumetric OB formed two days ago on the
four-hour chart. The OB has a high formation volume printed in the box. There
is a small bullish FVG directly below it. The ZigZag projection lines show a
target area just above the OB. Price pulled back into the OB yesterday and
printed a wick rejection. On the intraday fifteen-minute chart you saw a
bullish engulfing candle inside the OB, closing above the mid-line.
Interpreting this:
OB formation with high volume suggests real institutional
activity.
FVG overlapping adds imbalance confluence.
projection alignment adds structural confluence.
intraday rejection and close above mid-line provide entry
confirmation.
mitigation has not occurred by close method, so the OB is
still valid.
This is the kind of multi-layered setup the script is
designed to reveal quickly. You’d size your trade with ATR and place stops just
outside the OB. The script’s labels make this whole reading easier.

Frequently Asked Questions
Q. What exactly is a Fair Value Gap and how does it differ
from an order block
A Fair Value Gap is a three-candle imbalance where price
skipped trading within an area between those candles. An order block is the
last candle before a large institutional push. They are related but different.
FVG is an open, inefficient area. Order block is where big orders likely
originated. When the two line up, you get better setups.
Alchemy Markets
+1
Q. Which mitigation mode should I pick as a beginner
Start with "Close" mitigation. Wicks are noisy.
Close-based mitigation is stricter and reduces false signals. As you gain
experience, you can test "Wick" or "Avg".
Alchemy Markets
Q. On which timeframes does this work best
Higher timeframes are more reliable for order blocks and
FVGs. Try one-hour, four-hour, and daily charts. Lower timeframes can be used
but require higher noise reduction.
EBC Financial Group
Q. Can I automate entries with this indicator
The FVG detection and OB formation are programmatic, so you
can automate. But automatic entry decisions should be combined with additional
confirmation to avoid false fills. Many traders code bots that only signal and
then wait for lower timeframe confirmation.
trenddaytrader.com
Q. Does volume always confirm institutional activity
Not always. Volume is context dependent. A high-volume pivot
on a small-market altcoin means less than the same volume on EURUSD. Always
consider asset liquidity and market hours.
EBC Financial Group
Q. Will the indicator repaint
The script uses pivot functions and tracks blocks via
arrays, and only displays blocks on the last bar. Like many overlay indicators,
past boxes are recalculated at real-time end of bar, but the script tries to
avoid ephemeral repainting by drawing only confirmed pivots and cleaning up
boxes on completion. Still, use caution and test on replay to see actual
behavior.

A short checklist you can print and keep on your desk
Use HTF for initial OB identification.
Prefer "Close" mitigation until you’re
comfortable.
Favor OBs that overlap with FVGs or structural pivots.
Confirm with price action rejection before entering.
Size with ATR or % of account.
Track and record outcomes for at least thirty trades before
changing the system.
Conclusion
The Price Action Volumetric Order Blocks indicator is a
layered tool that tries to combine the best of Smart Money Concepts, imbalance
detection, and volume context. For a beginner, it’s a powerful learning device
because it makes institutional footprints visible and quantifiable. But with
power comes complexity. Start slow. Use the noise filters. Teach yourself to
read the boxes and the labels. Make small, disciplined trades and document
everything. Over time you’ll learn which OB types and FVG contexts your market
and timeframe respond to.
If you follow the practice steps here and backtest
thoroughly, you’ll develop a clear, repeatable method to trade with
institutional flow rather than against it. Remember, this isn’t magic. It’s an
approach that helps you think like a participant who respects where the big
orders are. In trading, that matters a lot.
