The opening price of 127.7969 should be about 25.5 of 32, and the expression is 127-25 (5).
The closing price of 127. 1406 should be about 4.5 of 32, and the expression is 127-4 (5).
As usual, 25.5-4.5=2 1 1 is 3 1.25 USD, and the profit is 21* 31.25 USD.
It's been a long time, but I forgot whether it was expressed in this way.
I wonder if this expression is 127-25+ 127-4+
