2 month:- net payment is euro 393,265
3 month :-net payment is euro 676,928
3 month :- reciept is KR 8.6 million

Foreign exchange rates:
Dkroner/£ Euro €/£
Spot 10.68 – 10.71 1.439 – 1.465
Two months forward 10.74 – 10.77 1.433 – 1.459
Three months forward 10.78 – 10.83 1.431 – 1.456

Profit or loss
April – to buy 0.6983
July – to sell 0.7002 (1)
0.0019 profit

WN 1

End of April End of July
September future 0.6983 0.7002
Spot (1/1.439)ie 0.6949 0.6988 ie (1/1.431)
0.0034 * 2/5 0.0014

1)for end of april why did we take 1/1.439 and for july 1/1.431
2) when do we know we are supposed to take the reversal of exchange rate rate ie 1/1.439 my guess is that future contracts are given as “pound per euro” and spot rate is “euro per pound?

my answer
normally dont we do

Future price -0.6983
Spot-(1/1.431)=0.6986
=0.0005*(2/5)
=.0.0002

Expected rate is 0.6983+.0002=0.6985

net outcome is

Buy at 0.6983
sell at 0.6985

also there is no tick size or price given here so why does the solutions say

Profit or loss
April – to buy 0.6983
July – to sell 0.7002 (1)
0.0019 profit
Profit per contract = 19 ticks * £12.50
= £237.50
is it a standard procedure to calculate ticks here…my answer
125000*.0.0019*5=1187.5 same as above

3)so why did they specifically mention tick size when its not given?

its so confusing when they use ticks when the question doesnt mention it
