ICT所說的Fair Value Gap（以下簡稱FVG）一樣有詳細的定義：
Fair Value Gap is a range in price delivery where one side of the market liquidity is offered and typically confirmed with a liquidity void on the lower time frame charts in the same range of price. Price can actually "gap" to create a literal vacuum of trading thus postiong an actual price gap.
翻譯成中文的意思就是：
公允價值缺口是指市場一方提供流動性的價格交付範圍，通常在同一價格範圍內的較低時間框架圖上確認流動性空白，價格實際上可以 "跳空"，形成實際的交易真空，從而形成實際的價格缺口。
