[Chimemena]

he neither make profit nor loss.

 

[Tanganyika1]

yes he made a profit, coz it look like he was not through by the book the time he sold it for the first time. Thats why he needed it back to finish some readings on the left pages and resold it when he was through.

In real time he neither had profit nor loss. But you didn't mentioned the time lapse for the transactions occured which has a direct impact on exchange rate. Remember,having $1 today is not equal with having $1 tomorrow!.

the exchange rate is the other side of the coin, we are not finding the value of the $s subjected to time.

[TANMO]

He made a 20$ profit..

Bought it for 70 then sold it for 80 = +10
Bought it again for 90 (90-70) +10 = -10
Then sold it for 100 (100-70-10) = +20
