(1) 假设我手上有1000只股票，我可不可以write > 1000 CALL options, 还是有什么限制？
In most cases, if you write a covered call on a stock you own, it should be ok. The brokerage firm where you have your trading account might need you to sign up for covered options level trading.
If you own 1000 shares of ABC stock, you can write 10 calls against it because each option represent 100 shares.
Example,
You own 1000 shares of MOT
You can write (sell to open) 10 3 month MOT 17.5 Calls for a premium of .80 per contract, so you will recive 10*100*.80=$800.
Since you write a covered call, the MOT shares will be locked (meaning you can't sell it) by the brokerage firm until you buy to close your short call position or the short call options position expires.
In additon, you might be assigned by the buyer of your call options to delivery your MOT shares. (see cash settlement below).
>> 能不能卖些空头Option, no underlying security as collateral)
Not recommended due to the high risk for unhedged option positions.
(2) 假设俺买了些Call options, 等到maturity date, 帐户上银子不够 N * Strike Price,那俺改如何是好？
If your long call options has value (in the money) at expiration date (not maturity date, which is mostly used for bonds), you can choose settle in cash, instead of call the other side to delivery the actual stocks.
Most options expire worthless, for these with value, most of them settle in cash.
Hopefully this helps...
