Institutional Order Flow

INSTITUTIONAL ORDER FLOW

===========================

OVERVIEW

--------

Institutional Order Flow is a price-action based volume indicator

designed to visually highlight moments where large volume enters the

market but fails to move price significantly in that direction. This

phenomenon is commonly referred to as "absorption" — where aggressive

buying or selling is being absorbed by opposing limit orders, often

indicating the presence of large institutional players, smart money,

or algorithmic trading activity.

The indicator plots colored bubbles directly on the price chart at the

exact bar where absorption is detected, with the SIZE of each bubble

scaling dynamically based on the strength of the absorption event.

Bigger bubbles represent stronger, more significant absorption —

helping traders instantly distinguish minor noise from major,

potentially market-moving institutional activity.

WHAT IS ABSORPTION?

--------------------

Absorption occurs when one side of the market (buyers or sellers)

pushes aggressively into price, generating a volume spike, but the

opposing side "absorbs" that pressure — resulting in a long wick and

little to no net price movement in the aggressor's favor. This is

often the footprint left behind by large institutional orders working

against retail flow.

- BUY ABSORPTION: Heavy selling pressure hits the market (often visible

  as a long lower wick), but buyers step in and absorb it, preventing

  price from falling further. This can signal a potential reversal to

  the upside or the presence of a strong institutional support zone.

- SELL ABSORPTION: Heavy buying pressure hits the market (long upper

  wick), but sellers absorb it, capping the advance. This can signal

  a potential reversal to the downside or a strong institutional

  resistance zone.

HOW IT WORKS

------------

The indicator combines two independent conditions to confirm

institutional absorption:

1. VOLUME SPIKE DETECTION

   The script calculates a moving average of volume over a user-defined

   lookback period (default: 20 bars). A bar is flagged as "high volume"

   when its volume exceeds this average multiplied by a sensitivity

   factor (default: 1.5x). This filters out ordinary volume fluctuations

   and isolates genuine institutional-sized spikes.

2. WICK RATIO DETECTION

   For each bar, the script measures the lower wick (rejection of lower

   prices) and upper wick (rejection of higher prices) relative to the

   bar's total range (high minus low). A minimum wick ratio (default:

   50%) must be met for a bar to qualify as showing rejection strong

   enough to represent institutional absorption rather than simple

   continuation.

Only bars that satisfy BOTH conditions simultaneously — a volume spike

AND a dominant wick — are marked as institutional order flow events.

DYNAMIC BUBBLE SIZING

-----------------------

Once a bar is confirmed as an absorption event, the indicator calculates

a "strength score" for that bar. This score combines:

  - How far volume exceeded the volume spike threshold

  - How far the wick ratio exceeded the minimum wick threshold

The two factors are multiplied together, so an event with BOTH

extremely high volume AND an extremely long wick — the clearest sign

of large institutional participation — produces a much higher strength

score than an event that only barely qualifies.

This strength score is then mapped into four visual size tiers:

  SMALL - Minor absorption, volume/wick just above threshold

  MEDIUM - Moderate absorption, noticeably above threshold

  LARGE - Strong absorption, well above threshold

  XL - Extreme absorption, likely large institutional trades

Each tier is rendered with a progressively larger bubble, giving traders

an immediate visual sense of institutional conviction strength without

needing to hover over or inspect individual bars.

INPUTS

------

- Volume Average Length (default 20)

  Number of bars used to calculate the baseline average volume. Shorter

  lengths make the indicator more reactive to recent volume changes;

  longer lengths smooth out noise and focus on more significant

  institutional-sized spikes.

- Volume Spike Multiplier (default 1.5)

  How many times above average volume a bar must be to qualify as a

  volume spike. Increasing this value filters for only the most

  extreme, likely institutional, volume events.

- Minimum Wick Ratio (default 0.50)

  The minimum proportion of the bar's total range that must be composed

  of rejection wick. Higher values require more dramatic rejection

  before flagging institutional absorption.

VISUAL OUTPUT

--------------

- LIME/GREEN bubbles (below price): Buy-side institutional absorption —

  sellers were absorbed, potential bullish signal or support forming.

- RED bubbles (above price): Sell-side institutional absorption —

  buyers were absorbed, potential bearish signal or resistance forming.

- Bubble size: Represents the relative strength of the institutional

  order flow event, from small (minor) to XL (extreme/high-conviction).

HOW TO USE IT

--------------

1. Watch for clusters of same-colored bubbles, which may indicate a

   developing institutional support or resistance zone being

   repeatedly defended.

2. Pay closer attention to LARGE and XL bubbles, as these represent

   the most significant absorption events and are more likely to be

   associated with genuine institutional or large-trader activity.

3. Combine with other tools such as trend structure, order blocks, or

   key support/resistance levels for higher-confidence signals. This

   indicator is best used as a confirmation tool rather than a

   standalone entry trigger.

4. Consider adjusting the Volume Average Length and Volume Spike

   Multiplier depending on the asset and timeframe — highly liquid

   assets or lower timeframes may require more conservative (higher)

   thresholds to avoid excessive signals.

LIMITATIONS

------------

- This indicator is reactive, not predictive — it identifies

  institutional order flow footprints after the bar has closed and

  does not forecast future price movement.

- Volume data quality varies by asset and exchange. On markets with

  incomplete or aggregated volume feeds (e.g., some spot crypto pairs

  or forex), signal reliability may be reduced.

- Absorption does not guarantee a reversal; it only indicates that

  significant opposing pressure was present. Price may continue in

  the original direction after a period of consolidation.

- As with all volume/wick-based tools, this indicator works best in

  liquid markets with consistent volume reporting, and may be less

  reliable during illiquid sessions, holidays, or on synthetic indices.

- The term "institutional" refers to the inferred size/character of the

  order flow based on volume and price rejection patterns — it does not

  confirm the actual identity or intent of market participants.
