3.3. THE LAW OF ONE PRICE FOR SPOT EXCHANGE QUOTES 99
Figure 3.12:A Dealer’s Shopping-Around SpreadsheetKeyCourtesy of Paul Goossens, dealer atKBCBrussels. Paul’s spreadsheet shows the best quotes fromEBS’s broking screens, from Reuters Dealing2002, and the indirect quotes (viausdoreur). The latter are obviously rounded. Check how the indirect quotes are always wider at one side at least.(With only two pips between the best direct quotes, and with rounding of the synthetic quotes, one side must always seem to match.) The wider quoteslabeled Reuters are the indicative, non-binding ones from theReuters FX/FXpages; they mean nothing except that that some banks are willing to quote.See how Paul’s sheet gets theeur/usdquote fromEBSinto the black&green part of the spreadsheet. Cell 1 is selected; spot the underlying command=RtGet(‘‘IDN’’:‘‘EUR=EBS’’:‘‘BID’’)in theenter functionbox above the spreadsheet. From the imported data in the black part, synthetic ratesare computed.
