阐述了动力煤市场价格规律连续及平滑变化的特点。认为,现货市场以尽可能细分的计价区间,力图贴近市场价格规律,而动力煤期货由于计价区间跨度过大,与规律的贴合度远不如现货市场。为此提出以价格关联函数计算式进行交割计价方法。 The characteristics of continuous and smooth price changes of thermal coal market are expounded. That the spot market as much as possible breakdown of the price range, trying to close to the law of the market price, and steam coal futures due to the span of the pricing range is too large, and the laws of compliance is far better than the spot market.
