补充资料：成交量、未平仓合约量与价格的关系
成交量、未平仓合约量与价格的关系
【成交且、未平仓合约，与价格的关系】成交量和未平仓合约量的变化会对期货价格产生影响，期货价格变化也会引起成交t和未平仓量的变化。因此，分析三者的变化，有利于正确预测期货价格走势。 1.成交t、未平仓合约里增加，价格上升，表示新买方正大t收购，近期内价格还可能继续上涨。 2.成交t、未平仓合约t减少，价格上升，表示卖空者大t补货平仓，价格短期内向上，但不久将可能回落。 3.成交t增加，价格上升，但未平仓合的t减少，说明卖空者和买空者都在大t平仓，价格马上*下映。 4.成交t、未平仓t增加，价格下肤，农明卖空者大t出咨合的，短期内价格还可能下跌，但如抛省过度，反可能使价格上升。 5.成交t、未平仓t减少，价格下肤，农明大t买空者急于卖货平仓，姐期内价格将峨续下降。 6.成交量增加、未平仓量和价格下跌，表明卖空者利用买空者卖货平仓导致价格下跌之际陆续补货平仓获利，价格可能转为回升。 从上分析可见，在一般情况下，如果成交量、未平仓量与价格同向小幅变化，则其价格趋势可继续维持一段时间;如两者与价格反向变化时，价格走势可能转向。当然，这还需结合不同的价格形态作进一步的具体分析。
