外汇市场:价格反应和价差影响

Foreign exchange markets: price response and spread impact

Juan Camilo Henao Londono, Thomas Guhr

摘要:

我们对不同年份、不同时间尺度的即期外汇市场价格响应函数进行了详细的大规模数据分析。这样的响应函数提供了关于偏离马尔可夫行为的定量信息。价格响应函数显示,随着时间滞后的增长,在贸易时间尺度和物理时间尺度上,所有分析年份的价格响应函数都增加到最大值,然后缓慢下降。此外,我们使用一个价格增量点(pip)买卖价差的定义来分组不同的外汇对和分析的价格反应函数的价差的影响。我们发现,大点差有一个更强的影响的反应。这与股票市场的情况相似。

英文摘要:

We carry out a detailed large-scale data analysis of price response functions in the spot foreign exchange market for different years and different time scales. Such response functions provide quantitative information on the deviation from Markovian behavior. The price response functions show an increase to a maximum followed by a slow decrease as the time lag grows, in trade time scale and in physical time scale, for all analyzed years. Furthermore, we use a price increment point (pip) bid-ask spread definition to group different foreign exchange pairs and analyze the impact of the spread in the price response functions. We find that large pip spreads have a stronger impact on the response. This is similar to what has been found in stock markets.
