IB auto liquidation

Discussion in 'Retail Brokers' started by bestfriend, Aug 22, 2007.

  1. Can someone please explain how this works if a trade occurs pre or post market that would reduce your equity below zero?

    Say, a single 100 lot goes off outside the market, will an auto-liquidation occur?Waht about a series of trades that occur pre- or post? Do they wait for the core session or when there is more volume?

  2. Maintenance Margin Calculations

    ON A REAL-TIME BASIS excess liquidity is checked to ensure that it's >=0. If it is negative, the account is subject to liquidation on a real-time basis. The following calculations are used to determine excess liquidity:
    Securities excess liquidity = Securities equity with loan value - Securities maintenance margin requirements

    Commodities excess liquidity = Commodities net liquidation value - Commodities maintenance margin requirements

    In addition, any account that has negative cash on a trade date or settlement date basis will be liquidated. It should be noted whereas futures cash settle each night, options are generally treated on a premium style basis and will not cash settle until the options are sold or expire. Therefore, for certain combination futures and options positions there may be a mismatch in cash flows which could cause cash to go negative even though Net Liquidation Value is positive. In addition, there are a handful of options where local custom is to cash settle the option each night at the clearing house (e.g. HKFE HSI Options), but due to system constraints we margin these options on a premium style basis.
    Reg T End of Day Margin Calculations (Securities Cash and Reg T accounts only)

    AT THE END OF EACH US TRADING DAY (15:50-16:00 ET), a Special Memorandum Account (SMA) is checked to ensure that it's > =0. If it is negative, the account is subject to liquidation. In addition, no cash withdrawal will be allowed that causes SMA to go negative on a real-time basis.

  3. So are you saying a single trade of 100 shares away from the market pre or post could force an autoliquidation event? Or do you know? Or, would they wait for the core session?
  4. Off the regular market hours trade can cause auto-liquidation if excess liquidity drops below 0. The volume of trading has no affect on auto-liquidation event being triggered. Only your money is at risk all the time and never of the broker.

  7. Interesting question.

    There are frequently bad/fake/bs trades that take place pre/post market.

    Less lately then there used to be , but they are there.

    Now, if you are long a stock and it trades at 1 cent, will you be liquidated?

    Or if you are short, and it trades at $9999, will you be liquidated?

    I've never heard of it, and IB is not that dumb.

    But, it would be nice to find out what they do to prevent bad liquidations.
  8. The stock is priced at $9999 when the market is closed for this stock. You'll never see stock was actually traded at this price.
  9. an "erroneous trade"

    whether it be stocks futures options etc

    needs to be reported
    ASAP to your broker so they can
    argue on your behalf with the
    exchange or ECN that the trade
    is erroneous and should be "busted or adjusted"
  10. ids

    ids Interactive Brokers

    Liquidations are limited by certain time brackets. For example, all US products except some very liquid futures could be liquidated only between 9:40 and 16:00 EST.
