A 公允价值缺口 (FVG) is one of the most powerful concepts in Smart Money trading. It represents a price imbalance — a zone where institutional orders moved price so aggressively that no two-way auction occurred. 何时 price returns to fill this gap, it 创建s one of the highest-probability 入场 设置s available.
如何 FVGs Form
An FVG is a three-candle 模式 where the wick of candle 1 and the wick of candle 3 don't overlap. The space between them is the 公允价值缺口. The middle candle (candle 2) is the displacement candle — a moment of aggressive institutional order flow that left an imbalance in the order book.
For a bullish FVG: the gap sits between the high of candle 1 and the low of candle 3 during an upward move. For a bearish FVG: the gap sits between the low of candle 1 and the high of candle 3 during a downward move.
为什么 FVGs Get Filled
The reason is rooted in market microstructure. 3月ket-making 算法s are designed to seek price efficiency. 何时 price moves too fast in one direction, it 创建s an inefficiency — a range where buyers and sellers never properly matched. These 算法s will guide price back to these zones to rebalance the order book. Research shows approximately 70-80% of FVGs on the 1H timeframe and above get at least partially filled within 20 candles.
The 5-Point Quality Filter
1. HTF Alignment: The FVG must form in the direction of the higher-timeframe 偏向. A bullish FVG on the 15M chart is far more reliable when the 4H structure is also bullish.
2. Displacement Strength: The middle candle should show strong momentum — a large body relative to recent candles, ideally closing near its extreme. Weak, small-bodied candles produce unreliable FVGs.
3. Unmitigated Status: A FVG that has already been tested is "mitigated" and loses most of its edge. Focus on fresh, untested gaps.
4. Confluence: 最佳 FVGs overlap with an order block, key liquidity level, or 斐波那契 zone. Multiple 汇合s dramatically increase win probability.
5. Session Context: FVGs formed during high-volume sessions (London open, NY open) are more reliable than those formed during low-volume periods (late Asian session for forex).
Entry Mechanics
The standard 入场 is at the 50% mark of the FVG — the midpoint between the top and bottom of the gap. This gives optimal risk-to-reward. Stop loss goes beyond the entire gap. If the full gap gets swept with a candle body close, the thesis is invalidated. Target the next significant structure level or opposing liquidity pool.
Common Mistakes
1. Entering on first touch without 确认. Wait for a rejection candle (pin bar, engulfing) at the FVG boundary. 2. Trading FVGs against HTF trend. This dramatically reduces your edge. 3. Ignoring volume 背景. Low-volume FVGs get swept entirely rather than providing clean entries. 4. Trading already-mitigated FVGs. First touch is the highest probability — don't trade the second or third retest.
Quantum Algo FVG Detection
Quantum Algo automatically identifies every valid FVG 覆盖所有时间框架 on your TradingView chart. It color-codes by type (bullish/bearish), tracks mitigation status in real time, and filters low-quality imbalances using structural 背景. The multi-timeframe panel shows HTF FVGs directly on your 入场 timeframe so you never miss a high-quality 设置.
