Trading Terminologies & Abbreviations with Examples

·

Understanding the language of trading is essential for navigating financial markets with confidence and precision. Whether you're analyzing forex, indices, or cryptocurrencies, mastering key terminologies and abbreviations helps you interpret price action, identify institutional behavior, and make informed decisions. This comprehensive guide breaks down essential trading terms—complete with clear definitions and practical context—to serve as your go-to reference.

What Is Break of Structure (BOS)?

A Break of Structure (BOS) occurs when the price moves beyond a recent significant high or low, signaling a potential continuation of the trend. This concept is foundational in identifying shifts in market direction.

Traders use BOS to confirm momentum and validate entry points within trending markets.

Understanding Double and Minor Breaks of Structure

dBOS (Double Break of Structure)

When price consecutively breaks through two significant levels—such as two swing highs or lows—it’s referred to as a dBOS. This pattern often indicates strong institutional participation and reinforces the validity of the ongoing trend.

mBOS (Minor Break of Structure)

An mBOS refers to structural breaks occurring on lower timeframes (e.g., M15 or M5). While less significant than higher timeframe breaks, these can signal early entries or short-term momentum shifts when aligned with the broader trend.

Order Blocks (OB): The Institutional Footprint

An Order Block (OB) represents a zone where large market participants—like banks or institutional traders—are believed to have placed substantial buy or sell orders. These appear as the last opposing candle(s) before a strong directional move.

These zones often act as future support or resistance areas where price may react.

Area of Interest (AOI) vs. Point of Interest (POI)

AOI (Area of Interest)

An AOI is a broader zone where traders anticipate price reactions due to confluence factors such as order blocks, imbalances, or Fibonacci levels. It's not a precise level but rather a region of potential reversal or continuation.

POI (Point of Interest)

Also known as a Decision Point (DP), a POI is a specific price level where market participants are likely to make trading decisions. This could coincide with key support/resistance, previous highs/lows, or liquidity pools.

Imbalance (IMB) and Equilibrium (EQ)

IMB (Imbalance)

An Imbalance occurs when price moves rapidly in one direction with little to no retracement—creating a "gap" in fair price discovery. This inefficiency suggests one side (buyers or sellers) overwhelmed the other, leaving unfilled orders.

Key traits:

EQ (Equilibrium)

Equilibrium represents fair market value—typically around the 50% midpoint between recent swings. Markets often oscillate around this level during consolidation phases.

Inefficiency (INF) and Inefficient Price Action (IPA)

INF (Inefficiency)

This refers to abrupt, unbalanced price movements lacking proper retracement—often seen as large candles with minimal wicks. Such moves suggest forced action by institutions and are prone to retracement.

IPA (Inefficient Price Action)

Closely related to imbalance, IPA highlights unhealthy market structure caused by a lack of opposing participants. These zones become targets for future price fills and are central to Smart Money Concepts (SMC).

Liquidity (Liq) and Equal Highs/Lows

LQ / Liq (Liquidity)

Liquidity refers to areas where stop orders cluster—commonly below lows (buy-side liquidity) or above highs (sell-side liquidity). Institutions "hunt" these zones to trigger stops before reversing price.

EQL (Equal Lows) & EQH (Equal Highs)

These levels are critical for identifying potential reversal zones and breakout targets.

Institutional Trading (IT) and Smart Money Concepts (SMC)

Institutional Trading involves strategies used by large financial players who move markets. Identifying their footprints allows retail traders to align with dominant trends.

Signals of institutional activity include:

This framework is part of Smart Money Concepts (SMC), which decodes institutional behavior using price action rather than indicators.

Wyckoff Methodology (WKF): A Strategic Framework

The Wyckoff Method analyzes how institutions accumulate and distribute assets before major moves. Key components include:

These patterns help traders anticipate breakouts and reversals based on institutional accumulation phases.

Frequently Asked Questions (FAQ)

Q: What is the difference between BOS and dBOS?
A: A BOS is a single break of a key level, while dBOS confirms strength by breaking two consecutive levels—increasing confidence in trend continuation.

Q: How do I trade an imbalance zone?
A: Wait for price to return and fill the imbalance. Look for confluence with order blocks or AOIs before entering counter-trend trades.

Q: Why is liquidity important in trading?
A: Liquidity zones attract institutional orders. Traders watch these areas for stop hunts, reversals, or breakout accelerations.

Q: Can I apply SMC on any market?
A: Yes—Smart Money Concepts work across forex, crypto, stocks, and commodities because they focus on universal principles of supply, demand, and institutional behavior.

Q: What’s the best way to learn Wyckoff analysis?
A: Study chart schematics, practice identifying accumulation/distribution phases, and combine them with volume analysis for stronger signals.

Q: How do I use AOI and POI together?
A: Use AOI to define a reaction zone and POI as your exact entry trigger—such as a rejection candle or momentum shift at that level.
