回复：请教optio初级问题 如果有$2000能否进行1个股票价值$100的option交易?

Depends on the premium of the particular option you interest in and the margin requirements.

If you are on the long side only, margin doesn't matter. So let's see the option price. Except some options after split, one contract of option represent the right to long or short 100 shares of underlying stock at certain price(strike price). As long as you have cash more than 100 times the option price you want to long, you will be fine. (cash only, margin not work on longing option)
