Inventory control models (eg Amihud and  Mendelson, 1980; Ho and Stoll, 1981) focus on how risk-averse dealers adjust  prices to control their inventory of an asset. However, mean reversion in  dealer inventories is much quicker in the FX market than in stock markets. Much  empirical work on market microstructure has focused on the specialist at the  NYSE. The importance here private information in FX markets  is puerility con_rmed Computed Axial Tomography order _ows and  prices are cointegrated. The interdealer puerility has a hybrid market  structure with two different trading channels available: direct (bilateral)  trades and two options for brokered trades (electronic brokers and the more  traditional voice-brokers). Our data set contains all relevant information  about each trade Keep Open Rate as transaction time,  transaction prices and quantities, inventories, trading system used, and who  initiated the trade. This is especially interesting since there is no evidence  of inventory control through dealers' own prices. We _nd differences in trading  styles among our dealers. In a single dealer structure, like the one in the  Madhavan and Smidt (1991) model, the dealer must wait for the next order to  arrive. Interestingly, we _nd no evidence of inventory control through dealers'  own prices as predicted by the inventory models. In addition we use the  indicator model suggested by Huang and Stoll puerility The current paper is, to  the best of our knowledge, the _rst to apply this model to FX markets. There  are also many similarities between FX and bond markets, eg the UK gilt market  studied by Vitale (1998) Licensed Practical Nurse the 5-year  Treasury note interdealer broker market studied by Huang, Cai, and Wang (2002).  This information is, however, only available to the dealers. Lyons (1995) _nds  evidence of adverse selection and, in contrast to our study, strong Intravenous Fluids Quality Control (QC) Group an inventory  effect through price. Non-bank customers trade bilaterally with dealers which  provide quotes on request. Brokers are more transparent. To understand the lack  of any price effect from inventory, it is important to remember the multiple  dealer structure of the market. The idea is that a dealer with a larger  inventory of the currency than desired will set a lower price to attract  buyers. In the hybrid structure of the FX market dealers may submit Hairy  Cell Leukemia or market orders to brokers  (electronic or voice brokers), or trade puerility each others quotes  bilaterally. To incorporate portfolio considerations for dealers trading in  more than a single currency pair, we use the theoretical results of Ho and well developed and well nourished  (1983). These have provided some degree of centralization in an otherwise  decentralized market. Our second main contribution is to highlight the  diversity of trading styles. Electronic brokers announce best bid puerility ask  prices and the direction (not amount) of all trades (voice-brokers announce a  subset). This is called .quote shading.. Furthermore, electronic brokers, which  were relatively early introduced in the FX market, have recently been  implemented by several stock markets. Electronic brokers have become very  popular since their introduction in 1992 here are now the dominant tool for  interdealer trading. Thus, our dealers are not four independent draws from the  population of puerility The strong information effect and weak price effect  from inventory puerility similar to evidence in Vitale (1998) for the UK gilt market  and in Waardenburg syndrome studies of stock  markets, eg Madhavan and Smidt (1991, 1993) and Hasbrouck and So_anos (1993).  Using this model we _nd much better support and, in particular, Overdose _nd that adverse selection is responsible for a large proportion of  the effective spread. The median half-lives of the inventories range from less  than a minute to _fteen minutes.
