正在学习中, 准备开帐户,暂有俩问题...
1. 看了下面这个LINK, 似乎OPTIONSHOUSE最好, 我的理解对吗?
http://online-options-trading-review.toptenreviews.com/
then if I buy 1000 options, I should pay $235 (23.50 * 10)?
2. 下面这句话我不太理解: "So if the value of an option increases
sufficiently, it often makes sense to sell it for a quick profit...."
My question is why not exercise the option? My current understand is
exercise the option will get more money in absolute number but lower
percentage of gain, am I right? If yes, why they suggest to sell the option
for a quick profit? If no, can you help to explain why?
Sorry for typing english due to my slow typing in Chinese.
祝版友过年好, 马到成功发大财!

提前exercise相当于放弃时间价值了。只要不是spread非常大，卖掉总是比提前
exercise合算。
我有一次short option被对方提前exercise了，那个就是属于spread非常大的option。
另外，赞一下interactive brokers的强行平仓，破坏性比较小。我被强行平了好几次
，不过都基本没造成什么大的损失。

1. you should pay 8.5+1000*0.15 = 158.5，这是所有里面最低的，没有之一。
2. Why do you want to exercise it? options always come with some time value.
If you exercise an option with expiration date that is far away, you
basically lost your time value.
3. I have multiple popular broker accounts myself, but I chose OH as my
primary broker for option trading. If you were satisfied with my answer,
please use my referral to open the OH account.
