Wpływ publikacji danych makroekonomicznych na kurs EUR/PLN w kontekście badania mikrostruktury rynku
Market microstructure study of the EUR/PLN rate reaction to macroeconomic announcements

Summary/Abstract: In the paper we present the results of the study focused on the EUR/PLN exchange rate reaction to the publication of macroeconomic news concerning Polish economy in 2007. In the market microstructure study, on the basis of the order and trade data from the Reuters 3000 Spot Matching System, we proved that the information surprises are very quickly impounded into prices in limit orders submitted to the market. Nearly all information is built into the new FX rate during subsequent two minutes after the news publication. The significant role in this assimilation process plays the order flow (defined as a difference between volume of buy and sell transactions). It can be estimated that the contribution of order flow amounts to about 50% of FX rate changes induced by the arrival of new information.
