option expiration 问题# Stock

找了个link，还是不太清楚
http://www.optiontradingpedia.com/options_expiration.htm
ITM call，周六到期，如果（周六）帐面上有钱，就自动执行call。账户里会有stock。
问题1：执行call的时间是周六，对吧？
如果帐面上没钱，就自动执行call，同时把stock按市场价卖掉。
问题2：这个市场价应该是周六后的下一个开市日的开盘价，对吧？
问题3：如果帐面上有部分钱，怎么处理？全自动卖掉？还是卖掉钱不够的部分？
问题4：如果周末有大消息，导致周六后的下一个开市日的开盘价比执行call的价格
低，怎么处理？
问题5：如果问题4的答案是call自动作废，问题1的答案是周六自动执行，那么帐面
没钱明显是更好的选择。对不对？

就好像驾照笔考里挑最安全的答案一样，这些问题的答案直接往最对你不利的方向去考
虑。

如果没有钱，要自己处理掉。
否则会有严重犯规。

好像IB不支持这个，都让把itm的option提前卖掉
而且有文章分析过，对散户来说，留着itm的option到exp怎样也是不划算的

It seems not, based on the following from his link page:
"What happens if you hold an in the money call options or short put options
through expiration and do not have sufficient money to buy the stocks? In
that case, your broker will resolve the position by automatically selling
the stocks at the market price and posting the net profit or loss in your
options trading account."
To me, the only issue is you may loss some profit since the broker will sell
them at the after market price? which usually lower than the closed price,
but at least you don't need to worry about your account whether have money
or not. BUT you may loss money if the aftermarket bids are too low when
your profit is not much...
I am not sure if my understanding right or not, and I just acquired my
first calls yesterday, need to figure this out as well, any one can help to
make it clear? THanks.
