hey!

Could you please help me with how to calculate the bid-ask in points. I cant seem to understand how they have calculated their answers in the solution manual(questions 5).

4.Restate the following one-, three-, and six-month outright forward European term bid-ask quotes in forward points.

Spot1.3431-1.3436

One-Month1.3432-1.3442

Three-Month1.3448-1.3463

Six-Month1.3488-1.3508

Solution:

One-Month01-06

Three-Month17-27

Six-Month57-72

5.Using the spot and outright forward quotes in problem 4, determine the corresponding bid-ask spreads in points.

Solution:
