英文摘要：
  In this work we investigate tick-by-tick data provided by the TRTH database for several stocks on three different exchanges (Paris - Euronext, London and Frankfurt - Deutsche B\\\"orse) and on a 5-year span. We use a simple algorithm that helps the synchronization of the trades and quotes data sources, providing enhancements to the basic procedure that, depending on the time period and the exchange, are shown to be significant. We show that the analysis of the performance of this algorithm turns out to be a a forensic tool assessing the quality of the aggregated database: we are able to track through the data some significant technical changes that occurred on the studied exchanges. We also illustrate the fact that the choices made when reconstructing order flows have consequences on the quantitative models that are calibrated afterwards on such data. Our study also provides elements on the trade signature, and we are able to give a more refined look at the standard Lee-Ready procedure, giving new elements on the way optimal lags should be chosen when using this method. The findings are in line with both financial reasoning and the analysis of an illustrative Poisson model of the order flow.

中文摘要：
在这项工作中，我们调查了TRTH数据库为三个不同交易所（巴黎-泛欧交易所、伦敦和法兰克福-德意志B\\“orse）的几只股票提供的逐点数据在5年的时间里。我们使用一个简单的算法来帮助交易和报价数据源的同步，为基本过程提供了增强功能，根据时间段和交换情况，这些增强功能被证明是重要的。我们表明，对该算法性能的分析是一种评估聚合数据库质量的法医工具：我们能够通过数据跟踪所研究的交换上发生的一些重大技术变化。我们还说明了这样一个事实，即重建订单流时所做的选择会对定量模型产生影响，这些模型随后会根据此类数据进行校准。我们的研究还提供了有关商业签名的元素，我们能够更精确地查看标准Lee Ready程序，提供了使用此方法时应选择最佳滞后的新元素。研究结果与金融推理和订单流的说明性泊松模型分析一致。
