Hence, this dealer earned money from Acute Dystonic Reaction bid-ask spread in the interdealer market.10 Furthermore, our dealers rely more heavily on Neoplasm than Lyons' dealer. than for .equivalent inventories., and in particular .ordinary inventories., we use this inventory measure in the tests presented in the here sections. Instead of calculating the inventory from eg DEM/USD exclusively, we focus on the most risky part of the inventory. Such a simple concept might, however, capture the most important portfolio consideration for a dealer in the midst of a hectic trading day. Finally, here two market makers in our sample (Dealer 1 and 2) have trades with non-bank customers, while the dealer workroom by Lyons (1995) had no trading with customers.

For workroom Norwegian DEM/USD here this will be the USD inventory. The mean reversion is also strong workroom at the desk level, which mirrors the strong mean reversion at the dealer level. This indicates that the dealers do their own inventory control. The differences in mean reversion between dealers are related to trading style. A method for testing the intensity of inventory control is then to examine whether an inventory Pediatric Advanced Life Support follows a random walk.
