描述----------Description----------
Ten simulated price series for the 19 trading days in January 2010:
2010年1月的19个交易日中的10个模拟价格系列:
Ten hypothetical price series were simulated according to the factor diffusion process discussed in Barndorff-Nielsen et al. We assume that prices are only observed when a transaction takes place. The intensity of transactions follows a Poisson process and consequently, the inter transaction times are exponentially distributed. Therefore, we generated the inter transaction times of the price series by an independent exponential distributions with lambda = 0.1, which we keep constant over time. This means we expect one transaction every ten seconds. In a final step, the time series were aggregated to the 5-minute frequency by previous tick aggregation.
十大假定的价格系列进行了模拟根据因子在Barndorff-Nielsen等人讨论的扩散过程。我们假设价格交易发生时,只观察。交易的强度服从泊松过程,因此,跨交易时间均服从指数分布。因此,我们产生的价格序列间的交易时间由一个独立的指数分布λ= 0.1,随着时间的推移保持不变。这意味着,我们期待一个事务中每十秒钟。在最后的步骤,该时间序列被聚合到5分钟的频率由以前的刻度线聚合。
