Fair value gaps and liquidity voids look similar but form for different reasons. Here is when to trade each and how to combine them for higher-probability setups.
A Fair Value Gap (FVG) is a price range where very few trades occurred because price moved too fast. It appears as a gap between three candles: the middle candle moves so aggressively that it leaves space between the high of candle 1 and the low of candle 3 (bullish FVG), or between the low of candle 1 and the high of candle 3 (bearish FVG).
Why FVGs form: Institutional orders execute with urgency. When banks or large funds need to fill big positions quickly, they sweep available liquidity and leave gaps. Retail traders cannot react fast enough, so no trades happen in the gap zone. This creates inefficiency—an area where price left no transactions.
Bullish FVG example: Candle 1 closes at 1.0850. Candle 2 (middle candle) opens at 1.0855 and closes at 1.0880 with strong bullish momentum. Candle 3 opens at 1.0882 and closes at 1.0900. The gap is between the high of candle 1 (1.0850) and the low of candle 3 (1.0882). Price left 32 pips unfilled. That is an FVG.
Bearish FVG example: Candle 1 closes at 1.0900. Candle 2 drops fast from 1.0895 to 1.0870. Candle 3 opens at 1.0868 and closes at 1.0850. The gap is between the low of candle 1 (1.0900) and the high of candle 3 (1.0868). Price skipped 32 pips. That is an FVG.
FVGs attract price because they represent inefficiency. Markets seek equilibrium. When price moves too fast and leaves gaps, it often returns to fill those gaps before continuing. not always full fill, but partial fill is common. That return creates trading opportunities.
A liquidity void is a price zone where no transactions occurred at all—no candles touched the zone, not even with wicks. This happens when price gaps overnight, over weekends, or during extreme news events. It also happens when price moves so aggressively that entire price levels are skipped.
Difference from FVG: An FVG shows fast movement with a gap between candle bodies, but wicks might touch the zone. A liquidity void shows zero price action—no bodies, no wicks, nothing. The chart shows a blank vertical space (in rare cases) or a series of candles that completely avoid a horizontal zone.
Liquidity void example: Price closes Friday at 1.0850. Over the weekend, news breaks (geopolitical event, central bank announcement). Market opens Monday at 1.0920. There is a 70-pip gap. No candles exist between 1.0850 and 1.0920. That is a liquidity void. Price skipped the entire zone because no liquidity was available.
Intraday liquidity void: Price is at 1.0850. Major economic data releases (NFP, CPI). Price shoots up and reaches 1.0920 in 5 minutes. If you zoom into lower timeframes, you might see some candles, but on the 15-minute or 1-hour chart, the zone between 1.0860-1.0880 was never touched. That zone is a liquidity void.
Why liquidity voids form: No buy or sell orders existed at those price levels. Price had to jump to the next level where orders were waiting. This is common after long consolidations or near major round numbers (1.0800, 1.1000) where traders cluster stops and limits far away.
Trade FVGs for retracement entries. When price creates an FVG and continues in one direction, wait for price to retrace back into the FVG zone. Enter when price rejects the FVG edge with confirmation (wick, engulfing candle, momentum). FVGs often fill 50-70% before price resumes the original direction.
FVG entry example: Price creates bullish FVG at 1.0850-1.0882 (32 pips). Price rallies to 1.0920. Then price pulls back and enters the FVG at 1.0882. A 15-minute candle wicks to 1.0875 but closes at 1.0885 (rejection). Enter long at 1.0885. Stop below FVG at 1.0845. Target: next structure level at 1.0940.
Trade liquidity voids for continuation setups. After price fills a liquidity void (returns to the voided zone and fills it with candles), the next move is often a strong continuation. Why? Because once the void is filled, price found equilibrium and institutions are ready to push the original direction again.
Liquidity void entry example: Price gaps from 1.0850 to 1.0920 (70-pip void). Over the next day, price drops back and fills the void at 1.0870-1.0880. Candles now exist in the voided zone. Once the void is filled, price reverses and resumes the uptrend. Enter long when price breaks above the void fill zone (1.0880) with momentum. Target: 1.0940+.
The highest-probability setups combine multiple SMC concepts: order block + FVG + liquidity. When these align, win rate increases significantly because you have confluence—multiple institutional signals agreeing on the same zone.
Setup 1: Order block inside an FVG. Price creates bullish FVG at 1.0850-1.0882. Inside that FVG, there is a bullish order block (the last down candle before the rally) at 1.0860-1.0865. When price retraces into the FVG, it will likely react at the order block first (1.0860-1.0865). Enter there with tight stop below the order block (1.0855). High confluence = higher probability.
Setup 2: FVG near session high/low. Price creates bearish FVG at 1.0920-1.0945 during London session. Session high is 1.0940. When price retraces and enters the FVG + session high zone (1.0935-1.0940), institutions will defend this level aggressively. Enter short on rejection. Confluence: FVG + session high = strong resistance.
Setup 3: Liquidity void + structure break. Price gaps from 1.0850 to 1.0920 (void). Price drops back and fills the void at 1.0880. Then price breaks structure (BOS at 1.0900) confirming bullish momentum. Enter long on the BOS breakout. Confluence: void filled + structure break = institutional continuation confirmed.
The rule: Do not trade FVG or liquidity void in isolation. Look for confluence with order blocks, structure breaks (BOS), liquidity sweeps, or session levels. One signal is a guess. Three signals is a high-conviction trade. That is the difference between 50% and 70% win rate.
Mistake 1: Assuming every FVG will fill 100%. Most FVGs fill partially (50-70%) and then resume the trend. Traders who wait for full fill miss the entry. Enter when price enters the FVG zone and shows rejection, not when it fills completely.
Mistake 2: Trading FVGs on low timeframes without higher timeframe context. A 5-minute FVG inside a 1-hour bearish trend has low probability. The 1-hour bias will overpower the 5-minute retracement. Only trade FVGs that align with higher timeframe direction (1H, 4H).
Mistake 3: Entering liquidity voids before they are filled. Traders see a gap and enter immediately when price approaches the voided zone. But price might slice through the void without reacting and continue. Wait for the void to fill first (candles exist in the zone), then trade the continuation.
Mistake 4: Ignoring session timing. FVGs and liquidity voids work best during high-volume sessions (London, New York). If an FVG forms during Asia session (low volume), it is less likely to be an institutional move. Wait for London open to validate the setup.
Mistake 5: Trading FVG without stop loss. Some traders think FVG zones are guaranteed support/resistance. They are not. If price breaks through the FVG without rejection, the setup is invalid. Always place stop loss below the FVG (for longs) or above the FVG (for shorts). Protect your capital.
Fair Value Gap (FVG) = gap between candle bodies caused by fast institutional move (wicks may touch zone). Liquidity Void = price zone completely skipped (no bodies, no wicks, nothing). FVG shows fast execution. Void shows zero liquidity at those price levels. Both attract price return but form differently.
Look for 3-candle pattern: Middle candle moves so fast it leaves gap between high of candle 1 and low of candle 3 (bullish FVG), or low of candle 1 and high of candle 3 (bearish FVG). Gap shows few trades occurred in that zone due to institutional urgency.
No. Most FVGs fill partially (50-70%) before resuming trend. Enter when price enters FVG zone and shows rejection, not when it fills completely. Traders who wait for full fill miss entries. Partial fill + rejection = high-probability setup.
Trade continuation after void is filled. When price returns to voided zone and fills it with candles, next move is often strong continuation in original direction. Do not enter before void fills—price might slice through without reacting. Wait for fill, then trade breakout with momentum.
Highest-conviction setup: Order block inside FVG + session high/low. Example: Bullish FVG at 1.0850-1.0882, order block at 1.0860-1.0865. When price retraces into FVG, expect reaction at order block first. Enter with tight stop below OB. Confluence FVG + OB + session level = 70%+ win rate.
