你的buying power ...

你可以认真读一读：https://robinhood.com/us/en/supp ... ise-and-assignment/

> If you don’t have enough buying power or underlying shares to exercise your option, we may attempt to sell the contract in the market for you within the last hour before the market closes on the options' expiration date.

问题关键不是裸卖不裸卖，问题在于你的risk有多大，你的buying power足不足以支撑最坏的情况。btw，不代表真正行权后你的buy power还是正的。他们需要一定的余量保证。

卖put，single leg，我是从来没遇到过提前close，因为你已经抵押了足够的collateral去买对应的股票。你在12点PT被close，一般都是spread，而且你一定是卖的太多了。你可以试试只卖一个ATM的spread，你的buying power > 10w, 你看看会不会被提前close。

别家的risk control，比如etrade：https://us.etrade.com/l/h/options/expiration-process-risk
> E*TRADE reserves the right to liquidate or cover expiring option positions which would result in undue risk and/or margin deficit related to exercise or assignment.
> E*TRADE initiates expiration-related liquidations two hours prior to the market close but does reserve the right to begin the process sooner or later if conditions warrant any alteration

别家的也有类似的term，不去一一去找了。这个问题在blind上已经讨论过无数次了。
