sir 教以小搏大！

可能有所誤解！以小搏大是以小点數嬴倍數的悥思！如赢不到倍數收益那直博風險在垂直收缩期的風險就很高，開少点數的話如方向惜悟時输有限，因期權特性就算髙開或低開方向正確过佰点做 L 都會有可能輸的在兢縮時！
相反在同一時期做 S 的話就在較價外的風險是接近零直博律就比輆可取，就算方向惜唔只要結算曰不在行使價或價內都會變到零。

我成日誤會咗long 輸有限，贏無限，即用100點賺10=10%
D專家又話short賺有限，輸可以無限，即用7萬蚊做按金一張，贏100點=$5000，=0.714%
一直以來都誤會左，好在有Ching 解說；
如果期權金向垂直收縮的情况下，係咪short兩邊仲着數？淨係SC嘅原因係睇淡？

諗落又好有道理，如昨日在90點時SP188，收市140點都輸50點=2500，係按金嘅不足4%

Or just do the Put spread (L188P/S186P), if I were correct, there are a lot of 186P/180P OI.

For those who look for a rebound,

L192 @37
S194 @13
Debit 24pts ($1200) is a good bet.

or wait until tomorrow morning for a better deal.

Should eat 192 @70 / 194 @16.  

Example from last month, when direction is correct, might take profit (70 - 16 - 24 = 30pts = $1500).

If SC192/SP192 in Friday, the set cost around 600pts.
After big drop on Monday, the set cost around 400pts.
short兩邊 is not bad an idea, except for big gap against the strike price.

thanks for your information

期權其實正確係一種對冲工具，如單一做call / put 贏的機會細過玩大細，除賭方向之餘仲要賭埋時間，另外好多人以為short價外會好安全，其實遠價嘅點數同風險完全唔成正比例，所謂世事無絕對，分分鐘偷雞唔到蝕包米。
講到最精明期權玩家，必需具備如fatpat ching的策畧，在有限的損失情况下去賺取預期可能的利潤，期權=策畧，亦可做到贏多輸少，感謝fatpat ching的分享。
