I am having trouble interpreting quoted rollover rates. Is there a convention that a plus sign means a debit? For example, from http://www.citifxpro.com/rollovers Forex Cross Long Positions Short Positions AUDCAD -0.000427 -0.000611 Do these mean that I pay a charge whether long or short AUDCAD? Or does it mean that I earn a credit in either case? Or what does it mean? For another example. Forex Cross Long Positions Short Positions USDSGD 0.000026 -0.000028 Does this mean that I pay to be long USDSGD but I get a credit if I am short USDSGD? There are pairs for which both quotes are positive, and others where both are negative, which does not seem to make any sense to me. Thanks for any help.
