請問sma? - 理財

最近黃金跟美國現股壓很大 ,結果今天早上IB寄給我這個

Based upon a review of your SMA balance, your account is not projected to be
in compliance with the Regulation T initial margin requirement which goes
into effect in less than 10 minutes (15:50 ET). Note that accounts which
report SMA below USD 0 when Regulation T is enforced are subject to forced
liquidation of positions by IB to ensure margin compliance. To avoid this
action, please review your account balances within the TWS Account Window and
take the steps necessary to reduce margin exposure and restore your SMA
balance.

之後我有檔個股就被強迫出場了.....>_<

請教一下各位高手 我戶頭"剩餘流動性"還有三萬多
之前以為下單都是看這個...
原來是要看sma嗎....?
