+For example, if New Y ork coffee is trading at $1.41/lb and London coffee at $.80/lb, the equal-dollar-
+value spread would indicate a contract ratio of 1 New Y ork coffee/3 London coffee:

+Thus, in an equal-dollar-value spread position, 3 New Y ork coffee contracts would be balanced by 9 
+(not 5) London contracts.
+It may help clarify matters to compare the just-defined equal-dollar-value approach to the 
+equal-unit approach for the case of the New Y ork coffee/London coffee spread. Although the equal-
+unit spread is indifferent to equal absolute price changes, it will be affected by equal-percentage 
+price changes (unless, of course, the price levels in both markets are equal, in which case the two 
+approaches are equivalent). For example, given initiation price levels of New Y ork coffee = $1.41/lb 
+and London coffee = $.80/lb, consider the effect of a 25 percent price decline on a long 3 New Y ork/
+short 5 London coffee (equal unit) spread:

+Profit/loss in short London coffee position 52 20 43 0=× ×−,( $. 220 +2 20 43)$ ,=
+Profit/loss in sprea d1 7 613=− $,
+The equal-dollar-value spread, however, would be approximately unchanged:
+Profit/loss in long New York coffee positio n3 37 5000=× ×−,( $. .) $,3525 39 656=−
+Profit/loss in short London coffee position 92 20 43 0=× ×+,( $. 220 +3 96 77)$ ,=

+Returning to our original example, if the trader anticipating price weakness in London coffee rela-
+tive to New Y ork coffee had used the equal-dollar-value approach (assuming a 3-contract position for 
+New Y ork coffee), the results would have been as follows:
+Profit/loss in long New York coffee positio n3 37 5000=× ×−,( $. .) $,10 11 250=−
