Comprehensive Guide to Smart Money Concepts (SMC) and Candle Range Theory (CRT) Terminology Modern price action trading involves several concepts designed to help traders understand liquidity, market structure, institutional order flow, and price delivery. Two popular approaches are
Smart Money Concepts (SMC) and
Candle Range Theory (CRT). Both approaches focus on understanding how price behaves around important highs, lows, and liquidity levels. However, SMC provides a broader framework for analyzing market structure and liquidity, while CRT focuses on how price interacts with the high and low of a particular candle or trading range. Understanding their terminology can help traders build a more structured approach to technical analysis.
1. Smart Money Concepts (SMC) Smart Money Concepts is a price action framework that attempts to interpret market movements through liquidity, market structure, and areas of potential institutional order flow. SMC traders commonly study the following concepts:
Market Structure Market structure describes the direction and organization of price movement.
Higher High (HH): Price creates a new high above the previous high.
Higher Low (HL): Price forms a low above the previous low.
Lower High (LH): Price forms a high below the previous high.
Lower Low (LL): Price creates a new low below the previous low. An uptrend generally consists of higher highs and higher lows, while a downtrend generally consists of lower highs and lower lows.
Break of Structure (BOS) BOS occurs when price breaks an important swing high or swing low in the direction of the existing trend. Bullish BOS: Price breaks above a significant previous high. Bearish BOS: Price breaks below a significant previous low. It is commonly used to identify trend continuation.
Change of Character (CHOCH) CHOCH refers to an early indication that market behavior may be changing. For example, during a downtrend, price breaks above a previous lower high. This may suggest that bearish pressure is weakening. However, CHOCH alone does not guarantee a complete trend reversal.
Market Structure Shift (MSS) MSS describes a meaningful shift in price structure that may signal a change in directional control. Some traders use MSS and CHOCH interchangeably, while others distinguish them based on the strength and context of the structural break.
2. Liquidity Terminology Liquidity is one of the most important concepts in SMC. In trading analysis, liquidity often refers to areas where stop-loss orders and pending orders may be concentrated.
Buy-Side Liquidity (BSL) Buy-side liquidity is commonly located above important highs. Examples include: Equal highs. Previous day high. Previous week high. Major swing highs. Price may move toward these areas to interact with available orders.
Sell-Side Liquidity (SSL) Sell-side liquidity is commonly located below important lows. Examples include: Equal lows. Previous day low. Previous week low. Major swing lows.
Liquidity Sweep A liquidity sweep occurs when price moves beyond a significant high or low and then rejects the breakout area. For example, price breaks above equal highs but quickly returns below them. This may indicate a potential bearish reversal, particularly if followed by a bearish structure shift.
Liquidity Grab Liquidity grab is a commonly used term for a quick move beyond an obvious liquidity level to trigger orders. It is often used similarly to liquidity sweep, although terminology varies among traders.
Liquidity Run A liquidity run occurs when price breaks through a liquidity level and continues moving in the same direction toward another liquidity area. Unlike a typical sweep, price does not immediately reject the breakout.
3. Institutional Price Delivery Concepts SMC traders use several concepts to identify areas where price may react.
Order Block (OB) An order block is commonly identified as the last opposing candle before a strong directional move that breaks market structure. Bullish Order Block: Often the last bearish candle before a strong upward move. Bearish Order Block: Often the last bullish candle before a strong downward move. Not every opposing candle qualifies as a meaningful order block. Context, displacement, and structure matter.
Breaker Block A breaker block is an area associated with a failed order block that price later breaks through and may retest from the opposite side. For example, a bullish order block fails, price breaks below it, and the area later acts as resistance.
Mitigation Block A mitigation block is a concept used to describe an area where price revisits a previous price zone before continuing in a particular direction. Its exact identification rules differ between trading methodologies.
Fair Value Gap (FVG) An FVG is a three-candle price formation in which there is an imbalance between the first and third candles. Bullish FVG: A gap between the first candle's high and the third candle's low. Bearish FVG: A gap between the first candle's low and the third candle's high. Traders watch these areas because price may revisit them before continuing.
Imbalance An imbalance refers to an area where price moves rapidly in one direction, leaving relatively little two-sided trading activity. FVG is one commonly used way of identifying this type of price imbalance.
Displacement Displacement is a strong and decisive price movement, often characterized by large-bodied candles and a break of market structure. It may indicate strong directional momentum.
Premium and Discount Premium and discount are used to describe price locations within a selected trading range. Premium: The upper half of the range, above its midpoint. Discount: The lower half of the range, below its midpoint. Equilibrium: The 50% midpoint of the range. Traders often look for potential SELL setups in premium and BUY setups in discount, depending on the broader market direction.
4. Additional SMC Terminology Inducement (IDM): A price level that may attract traders into early positions before price moves toward a more significant liquidity area.
Internal Range Liquidity (IRL): Liquidity located within a defined price range.
External Range Liquidity (ERL): Liquidity located outside the boundaries of a defined range.
Optimal Trade Entry (OTE): A Fibonacci-based retracement area, commonly associated with the 62%–79% retracement zone in some ICT methodologies.
Point of Interest (POI): A price area where a trader expects a possible reaction, such as an order block, FVG, or breaker block.
5. What Is Candle Range Theory (CRT)? Candle Range Theory is a price action approach that studies the high and low of a selected candle to understand potential liquidity movements and price expansion. The selected candle creates a reference range. Traders then observe how subsequent candles interact with its high and low. A basic CRT concept involves three stages: Identify the reference candle. Observe price taking liquidity beyond one side of its range. Look for price to move toward the opposite side, subject to confirmation. CRT is not a universally standardized trading system. Different traders use different candle-selection rules, timeframes, and confirmation requirements.
6. Important CRT Terminology Reference Candle The candle selected to establish the trading range. It may be a daily, four-hour, one-hour, or another timeframe candle, depending on the trader's methodology.
Candle High The highest price reached by the reference candle.
Candle Low The lowest price reached by the reference candle.
Candle Range The distance between the reference candle's high and low.
Range Sweep Price moves beyond the high or low of the reference candle, potentially triggering liquidity outside the range.
Range Re-entry After moving outside the reference range, price returns inside it.
Opposite-Side Target The opposite boundary of the reference candle's range. For example, after sweeping the candle low and returning inside the range, traders may watch the candle high as a potential target.
Expansion A strong move away from the reference range, potentially toward external liquidity or another important price level.
7. Understanding CRT Through a Practical Example Suppose Gold (XAUUSD) has a reference H1 candle with: High: $2,500 Low: $2,480 Midpoint: $2,490 The next candle moves below $2,480, reaches $2,475, and then closes back above $2,480. This may represent a sweep of the reference candle's low. A trader should not automatically enter a BUY trade. Instead, the trader can wait for: Price to return inside the reference range. A bullish Market Structure Shift on the lower timeframe. A bullish displacement candle. A retest of the broken structure or relevant FVG. A confirmed candle close. The opposite side of the reference range, $2,500, may serve as a potential target. This is an illustrative example, not a guaranteed price movement.
8. SMC vs. CRT: Understanding the Difference Main focus Market structure and liquidity Reference candle range Key levels Swing highs and lows, OBs, FVGs Candle high and low Main concepts BOS, MSS, liquidity sweep Range sweep and re-entry Analysis Broad market context Defined candle range Trading objective Identify potential order-flow opportunities Identify potential range-based reversals or expansion SMC and CRT are not necessarily competing strategies. Some traders combine them to improve the quality of their analysis.
9. Combining SMC and CRT for XAUUSD A structured approach can help traders avoid entering trades based on isolated signals. For Gold trading, consider this framework:
Step 1: Identify the H1 Trend Look for higher highs and higher lows in a bullish market. Look for lower highs and lower lows in a bearish market. Avoid trading when the market is unclear or moving sideways.
Step 2: Mark the CRT Reference Candle Identify the selected candle's high and low. Keep these levels visible on the M15 chart.
Step 3: Wait for a Liquidity Sweep Observe whether price moves beyond one side of the reference range.
Step 4: Look for Market Structure Confirmation Wait for an MSS or CHOCH in the expected direction.
Step 5: Wait for a Retest Price may revisit the broken structure, an FVG, or another relevant point of interest.
Step 6: Confirm the Entry Enter only after a suitable candle closes in the expected direction.
Step 7: Manage Risk Place the stop-loss beyond the relevant sweep extreme or structural invalidation point. Define the take-profit before entering and keep position risk small.
10. Common Mistakes When Using SMC and CRT Treating every candle wick as a liquidity sweep. Assuming every FVG must be filled. Marking too many order blocks. Confusing a liquidity run with a liquidity sweep. Using CRT without clearly defining the reference candle. Entering immediately after a range breakout. Ignoring higher-timeframe market structure. Taking trades without a predefined stop-loss. Believing that institutional concepts guarantee profitable entries. These concepts are analytical tools, not proof of institutional intentions or guaranteed trading signals.
Conclusion Smart Money Concepts and Candle Range Theory offer different ways to study market behavior. SMC focuses on liquidity, structure, imbalances, and potential areas of institutional order flow, while CRT examines how price interacts with a selected candle's high and low. When used together with higher-timeframe analysis, lower-timeframe confirmation, and disciplined risk management, they can provide a more organized framework for understanding price action.
The key is to understand the range, identify the liquidity event, wait for structural confirmation, and execute only when the risk is clearly defined.
