Did a search on ET and I could not find the answer to the following: Do I check the Configure > Misc > Auto Future Rollover feature and wait for TWS to prompt me? I have a ZN short postion that I want to rollover. According to IB , short positions have to rollover 2 hours before the end of open outcry trading on the business day prior to Last Trading Day (shorts) (http://www.interactivebrokers.com/e...calDeliveryLiquidationRules.php?ib_entity=llc). Which is 9/21 for the ZN (http://cbot.com/cbot/pub/page/0,3181,1082+TY+all+2005,00.html) IB says TWS will prompt me to rollover 8 days prior to expiration.(http://www.interactivebrokers.com/php/webhelp/TWS_Menus/configure.htm#autoRollover) Is that 8 business days ie. 9/9, or is it 8 regular days ie. 9/13? More importantly can I rollover now without having to wait for TWS to send me a message or is liquidating and repositioning the the contract forward the only option. I called IB and the guy on the other end did'nt seem to have a clue. Hope someone can help out here.
