我 30/3 Long 19000 put @ 62  &  Short 19200 put @79  各3張
證券商收我按金正常，收我62*3*50 = 9300 期權金正常

但係點解我short 19200 put 的 79*3*50 =11850 佢唔俾番期權金我ge？

有無人知點解？

你在30/3 long 及put 的月份是幾時的呢 ?  若4月份的話, 都未到期又點比你 !
若果是3月份 , 照計都冇今高點數比你食呢 !  你看清楚再同你說 , 又不如你post 上來比大家替你睇睇再說呢 !

基本上3月份過期了 ! 你冇可能買到旣呢 !

Kongo :

   My idea is :
    Long Call & Put Option money deducted at once.
    Short Call & Put Option deposit money deducted at once.

    But same month Long Option money deducted can offset the Short Option money deposit required !

  Ask your Option Company for details.

AFOK

Thus, my calculation is your account deducted by :

         Long money 9,300 and unoffset Short money deposit 1,751.40 (11,051.40-9,300)
         =11,051.40 for this combination

fatpat

Long = you buy something, so you have to pay up front.
Short = you SELL insurance, so you have to put money into the account (for margin)
LP190 / SP192 diff = 200pts, so max loss is $10K.
Therefore you have to put money into the account

AFOK

Giving a very important hint re :  Margin on Protected Short Option with Unprotected Short Option.:
   When Long Put sold and made 2,000 Profit (say),but the SP 192 now unprotected.
   The margin needed from 11,051 to 41,760 (April 2 closing).

    BEWARE of great increase of margin from Protected Short Option to Unprotected Short Option !

AFOK

More specific, 41,760 margin for each piece of Option SP 192.

    BEWARE OF THIS 125,000 MARGIN NEEDED OF 3 PIECES SP 192 UNPROTECTED.
