I am pretty angry right now, so I am going to keep this brief. This is IB's new margin requirement - which was just posted to their website:
-------
"Patterned Day Trading" margin requirements are as follows:
Initial
Purchase: maximum (25% * marginable stock value, $25,000) or maximum (100% * non-marginable stock value, $25,000). From 15:50 - 16:00 ET, maximum (50% * marginable stock value, $25,000) or maximum (100% * non-marginable stock value, $25,000) will be applied.
Short sale: if last sale price/share >= $17 then maximum (25% * marginable stock value, $25,000), else if $17 > last sale price/share > $5 then maximum ($5 * marginable shares, $25,000), else if last sale price < = $5 then maximum (maximum (marginable market value, $2.50 * marginable shares), $25,000) or maximum (100% * non-marginable stock value, $25,000). From 15:50 - 16:00 ET, maximum (50% * marginable stock value, $25,000) or maximum (100% * non-marginable stock value, $25,000) will be applied. Short sale proceeds are applied to cash and the short position is subtracted from equity.
In addition for approving new opening orders in stocks, prior night's Equity with Margin Value (as of 16:00 ET) must be >= Account's Total Initial Margin Requirement.* Any opening stock order not meeting this criteria will be rejected.
*Example
A customer desires to purchase XYZ stock for $100. Equity with margin value (EMV) from prior night is $40, and current EMV is $100. Customer currently owns options with an initial margin requirement of $50. The customer would not be allowed to make this stock purchase as the $25 margin requirement (25%*100) for the stock plus the $50 margined requirement for the options is greater than the $40 EMV from the prior night. No liquidation would take place even though the option margin requirement of $50 is greater than last night's EMV of $40. In addition if a customer wanted to add an option position with an initial margin requirement of $40, it would be allowed as $50 + $40 is less than the current $100 EMV and the above rules do not apply to opening options and futures transactions.
Maintenance
Purchase: maximum (25% * marginable stock value, $25,000) or maximum (100% * non-marginable stock value, $25,000). If there was an increase in US securities positions between 16:00 - 15:50, between 15:50 - 16:00 ET initial margin requirements will be applied.
Short sale: if last sale price/share >= $17 then maximum (25% * marginable stock value, $25,000), else if $17 > last sale price/share > $5 then maximum ($5 * marginable shares, $25,000), else if last sale price < = $5 then maximum (maximum (marginable market value, $2.50 * marginable shares), $25,000) or maximum (100% * non-marginable stock value, $25,000). If there was an increase in US securities positions between 16:00 - 15:50, between 15:50 - 16:00 ET initial margin requirements will be applied. Short sale proceeds are applied to cash and the short position is subtracted from equity.

Can you believe that they instituted this rediculous structure without even giving us any notice?!! Even their help desk didn't have a clue what was happening! I wonder what recourse a trader that had a position liquidated while he was in compliance with their stated margin requirements would have? I am really pissed off that they would make a change like this without so much as a day's notice. I sent IB an e-mail and I hope some of the rest of you will too.
