Currency trading conversations unfold as challenge-engagement-repositioning sequences

Evidence

The core of the trading exchange begins in line 3, with an initiating question in which the London dealer asks for the price of 10 million U.S. dollars against Swiss francs, by typing “CHF,” “10,” and “PLS” (please). We call this a “challenge,” in accordance with the interactional understanding of the initiation as a competitive, economic, and potentially aggressive move (see below). The Zurich trader, whose initials are given (here: initials, spot dealer), responds by typing endpoints of a price range, “62” and “67,” meaning that he is willing to buy U.S. dollars at a rate of 1.4062 Swiss francs per dollar and to sell them at a rate of 1.4067 Swiss francs per dollar. In economic-interaction terms, he enters into an engagement with the challenger by offering a commitment to the price range to which he and the challenger are bound. The London dealer then selects the deal: he indicates that he wants to buy dollars by typing the last two digits of the Zurich trader’s selling price (“67”). Economically, the selection corresponds to a gain or loss on either side and to a corresponding repositioning of the parties in the market. The conversation concludes with a preprogrammed closing sequence that confirms the size of the deal, the date of the deal’s settlement (“VAL27NOV96”), the account to which the Swiss francs should be paid (“MY CHF TO DIRECT,” meaning GB1 Zurich), thanks, and a greeting. If the identification is included in the first term, then the sequential structure of global trading conversations corresponds to the pattern challenge-engagementrepositioning, or, in more neutral conversation analytic language, to an initiation-response-selection, followed by a closing sequence. — Karin Knorr Cetina & Urs Bruegger, Global Microstructures, 108
