(930 + 670) x $50 = $80000 with 20 contracts, which required around $65000 x 20 = $1300000 for deposit.
$80000 / $1300000 = 6.15% return for this month, and the annual return is 73.8%
Does it look ...

絕對正確, SPAN黎o架嘛, 計一邊就ok. 但係因為跨期, 未必完全抵銷margin, 所以可能都要$370k margin.
Hi, it's about 2:40am in Seoul.
Mr Tsang was quite right, the margin for each set of SP+SC was around $20,000.
'Ms?' oem, I have to work in any case coz my career nourishes my life and makes me meaningful in this universe. BTW, my salary is far beyond $80000, so I still have to work for survival(, and this is one of the reasons why I have the guts to trade a couple of high premium contracts at a time).
I still have to work on tomorrow and Sun. Sleep la........
