In the evolving world of trading, mastering abbreviations and concepts can transform how traders interpret charts and price behavior. Michael Huddleston developed the ICT (Inner Circle Trader) trading style.
It revolves around market structure analysis, liquidity concepts, and the trading behavior of large financial institutions such as banks and hedge funds.
The primary objective is to track and align with Smart Money movements. ICT traders use market structure, Break of Structure (BOS), Order Blocks (OB), and Fair Value Gaps (FVG) to identify optimal entry and exit points.
Central to this approach are the many ICT trading abbreviations, short forms, and terms that decode how prices move and why institutions act the way they do.
ICT (Inner Circle Trader) trading style vocabulary and acronyms
What is ICT Trading Style?
The ICT trading style is built on analyzing how banks, hedge funds, and large market participants manipulate price and liquidity.
Unlike indicator-heavy approaches, ICT focuses on understanding the market’s natural delivery algorithm. Traders who study ICT gain skills to:
- Identify market structure shifts;
- Track liquidity pools where orders are concentrated;
- Use Smart Money patterns to anticipate reversals and continuations;
- Enter and exit trades with precision through refined models.
The foundation of this style lies in recognizing abbreviations that explain structure, liquidity, and trading behavior.
Five Essential ICT Trading Abbreviations
In this part, we will explore five key concepts in the ICT trading style:
- Fair Value Gap (FVG)
- Market Structure Shift (MSS)
- Power of Three (PO3)
- Order Block (OB)
- Optimal Trade Entry (OTE)
Fair Value Gap (FVG)
A Fair Value Gap (FVG) forms when a three-candle sequence leaves an inefficiency between the first and third candle. In simple terms, it is a zone where price has not traded, leaving an imbalance.
Markets tend to revisit these gaps to rebalance price delivery. Traders using ICT methods monitor FVGs as potential retracement levels where entries or exits can be planned with greater accuracy.

Market Structure Shift (MSS)
The Market Structure Shift (MSS) highlights a change in directional bias. When MSS occurs, it signals that Smart Money may be transitioning from accumulation to distribution or vice versa.
Spotting MSS early helps traders adapt before the wider market reacts, making it a cornerstone for trend identification and reversal strategies.

Power of Three (PO3)
The Power of Three (PO3) describes the daily rhythm of markets: Accumulation, Manipulation, and Distribution.
During accumulation, price consolidates and builds liquidity. Manipulation often sweeps stops on one side of the range. Finally, distribution expands price in the intended direction.
Understanding PO3 equips traders to avoid false breakouts and align with institutional intent.
Order Block (OB)
An Order Block (OB) is a critical price zone left behind by institutional buying or selling. Bullish Order Blocks indicate areas of strong demand where Smart Money has accumulated long positions, while Bearish Order Blocks reveal supply zones where large sell orders originated.
Recognizing OBs allows traders to anticipate where the price may return for mitigation before continuing its move.

Optimal Trade Entry (OTE)
The Optimal Trade Entry (OTE) model integrates Fibonacci retracement levels with ICT concepts to refine precision. Typically, OTE zones between the 61.8% and 79% retracement levels provide highly favorable setups aligned with Smart Money’s direction.
This approach ensures traders enter with tight stop losses and maximize reward potential.
Market Structure Terminologies in ICT
ICT expands beyond the five abbreviations. Several terms explain the anatomy of price in greater depth and provide context for understanding trend development and reversals:
- Break of Structure: This occurs when the price breaks a previously established high or low, confirming that the market is continuing in the direction of the breakout. Traders look at BOS as validation of trend continuation or the start of a new leg in the market;
- BMS (Break of Market Structure): A Break of Market Structure goes beyond a single level break; it indicates a more significant shift in the market’s framework. BMS suggests that the overall trend may be reversing, making it an important signal for repositioning trades;
- CHoCH (Change of Character): A Change of Character happens when the market shows a sudden and clear change in direction. For example, if a series of higher highs suddenly shifts to lower lows, it reflects weakening momentum and can serve as an early warning of reversal;
- Change in State of Delivery: This term describes when the market’s price delivery mechanism shifts. It can represent changes in volatility, range behavior, or how price reacts around liquidity zones, often caused by algorithmic adjustments;
- CE (Consequent Encroachment): Consequent Encroachment refers to price re-entering a zone that was previously left untraded, such as the midpoint of a Fair Value Gap. CE is important because it shows the market rebalancing inefficiencies and can act as a magnet for price action.
Liquidity and Imbalance Abbreviations
Liquidity is central to ICT because it represents the pool of orders that institutions target to fuel price movement. In trading terms, liquidity is the availability of buy and sell orders at different price levels, and it acts as both a magnet and a driver for market behavior.
ICT methodology emphasizes identifying where these liquidity pools are located—above previous highs, below lows, or around consolidation zones—because Smart Money often pushes price into those areas to trigger stop orders and create the fuel for the next move.
By learning how liquidity functions, traders can anticipate these institutional maneuvers instead of being caught on the wrong side of them.
- BSL: Cluster of buy stops above market
- SSL: Cluster of sell stops below price
- LP (Liquidity Pool): Collection of orders
- LV (Liquidity Void): Empty trading zones
- PD Array: Premium/discount structure based on equilibrium

ICT Timeframes and Trading Sessions
Sessions play a vital role in price delivery. ICT highlights how different times create unique liquidity conditions.

Conclusion
The ICT trading abbreviations serve as the foundation of the Inner Circle Trader methodology and are essential for anyone seeking to decode institutional behavior.
By mastering concepts such as FVG (Fair Value Gap), OB (Order Block), MSS (Market Structure Shift), and PO3 (Power of Three), traders open a window into the institutional logic that governs market dynamics.
Each abbreviation addresses a building block: FVG reveals inefficiencies that attract price, OBs pinpoint the footprints of banks and hedge funds, MSS highlights pivotal turning points in direction, and PO3 explains the cycle of accumulation, manipulation, and distribution.
Together, these terms transform charts from random lines into structured maps of order flow and liquidity.
Beyond improving entries and exits, understanding ICT abbreviations helps traders anticipate liquidity hunts, identify premium and discount zones, and interpret the algorithms that drive price delivery.
In essence, they provide a shared vocabulary that connects individual traders to the deeper currents of institutional trading, enabling a shift from retail speculation toward Smart Money precision and long-term consistency.
