Total noob question regarding a contract

Ok suppose I have $200 in my account and I’m in a buy contract that’s on an up trend that’s currently spiking downward and my unrealized profit is at -$190 will my contract automatically close when it hit’s -$200 or will it continue to go until I have closed the contract?

Generally Speaking, a broker will not hold a trader responsible for an incurred debit as a result of a trade gone south. In other words, the trade ought to close if it reaches -200 leaving the account at $0.

I haven’t heard of a broker holding a client responsible for a debit balance, but be safe a check with your broker.
