Our main objective is to create an extensive database containing daily liquidity measures (ca. 30 variables) for the German equity market. The coverage will be 10 years and all stocks contained in the CDAX. This database will provide important input for future research in microstructure and related areas. The raw data (approximately three terabyte of intraday data) will be provided by Deutsche Börse AG. We will carefully screen the data and then aggregate it to the daily level. The daily data wil then be fed into a database that will be freely and at no cost available to other researchers. The only requirement is that researchers have to sign a form un which they guarantee that the use the data for research purposes only (and in particular not for commercial purposes), and that they will not make the data available to third parties. Deutsche Börse has explicitly granted us the right to make the daily data available in this particular way. A second objective of our project (closely linked to the first one) is the creation of a technical document. It will describe the contents and structure of the database in a way such that other researchers can work with the data. Our third objective is to write a paper that describes and analyzes the trading activity and liquidity on the German equity market. Obviously this paper will be based on the data set we intend to create. The fourth and final objective is to write a paper that analyzes the accuracy of low-frequency liquidity measures. Such measures have been proposed in the literature (starting with Roll 1984) in order to provide measures of liquidity that can be calculated when intraday data is unavailable (or too expensive or too cumbersome to use). Previous evaluations of such measures use different methodology and yield ambiguous results. Further, almost all previous papers conclude that the low-frequency measure which has been proposed in the respective paper fares better than all other measures. We plan to perform an analysis that is based on a broader sample (Germany and the US; this is warranted because the market structure in the two countries is distinctly different). We further plan to use a broader set of methods to assure the robustness of our results.

我们的主要目标是为德国股票市场创建一个包含每日流动性措施（约30个变量）的广泛数据库。覆盖范围将为10年，并且所有股票都包含在cdax中。该数据库将为微观结构和相关领域的未来研究提供重要的意见。 DeutscheBörseAg将提供原始数据（大约三个盘中数据的Terabyte）。我们将仔细筛选数据，然后将其汇总到每日级别。然后，每日数据将被送入一个免费的数据库中，该数据库将是免费的，而其他研究人员则无需使用。唯一的要求是，研究人员必须签署一种形式，他们保证仅将数据仅用于研究目的（尤其不是出于商业目的），并且他们不会向第三方提供数据。德意志·伯斯（DeutscheBörse）明确授予我们以这种特殊方式提供每日数据的权利。我们项目的第二个目标（与第一个密切相关）是创建技术文档。它将以其他研究人员可以与数据合作的方式描述数据库的内容和结构。我们的第三个目标是撰写一篇论文，描述和分析德国股票市场上的交易活动和流动性。显然，本文将基于我们打算创建的数据集。第四个也是最后一个目标是写一篇论文，以分析低频流动性测量的准确性。文献中已经提出了此类措施（从Roll 1984开始），以提供流动性的测量值，当日内数据不可用（或太贵或太昂贵或太麻烦而无法使用）时可以计算出来。对此类措施的先前评估使用了不同的方法，并产生模棱两可的结果。此外，几乎所有以前的论文都包括比所有其他措施更好的低频测量值。我们计划进行基于更广泛样本的分析（德国和美国；这是有必要的，因为这两个国家的市场结构明显不同）。我们进一步计划使用更广泛的方法来确保结果的鲁棒性。
