Cross Rate with Ask and Bid something, quotes, cross, Cross

bigredhockey55

When calculating cross rates when given bid-ask quotes, do we take the mid-point of each of the two bid-ask quotes to derive the third? Or do we do something fancy that involves up the bid and down the ask?

Newhuman

Ab x bc= ac

Ab/ac=cb

If you are given bid ask

Ab bid x bc bid= ac bid and vice versatile

Ab bid/ ac ask= cb bid and vice versa

When you calculate forward rate, you use midpoint for bid-ask .. however when calculating bid and ask, you dont use any midpoints.
