when buying options there's a few things to consider and one of the most important factors is the Delta
What Is Delta?
Delta is the ratio that compares the change in the price of an asset, to the corresponding change in the price of its stock. For example, if a stock option has a delta value of 0.65, this means that if the underlying stock increases in price by $1 per share, the option on it will rise by $0.65 per share, all else being equal. Delta values can be positive or negative depending on the type of option. For example, the delta for a call option always ranges from 0 to 1 because as the underlying asset increases in price, call options increase in price. put option deltas always range from -1 to 0 because as the underlying security increases, the value of put options decrease

Trader-101 樓主 : 所以這意味著當您查看一個買賣期權時,它在三角度下的期權上寫著 .50,我的意思是,對於該期權或股票增加的每美元,她每美元和售股權都會獲得五十美分,但它們完全相同,除了它們讀取負數,所以負數 51 意味著您每一美元下跌每美元收到 0.50 美元
Kittykiki : 唐克斯幫助我很多
MusikBox : 希望我知道我現在正在努力研究它
Lou Blacksail : 難怪我的交易不總是讓我賺錢,雖然股票價格上漲。然後,我似乎無法擺脫這些借記利差,我至少在 7 月。
Lou Blacksail : 任何人都知道任何方式能夠選擇單腿價格,而不必單獨購買 2 支借記點差?
jt compher : 很確定,如果增量是 .65,那麼對於每一美元,它都會增加它,您的價值將增加 65 美元。您在通話期權中擁有的 .65×100 股等於 65 美元。
