If i remember correctly, the API you have to download for a 32bit operating system despite you probably having a 64bit operating system, otherwise it does not work.
Leading on from my question.
Account Value $40000
10 minutes before the day session starts. Can I put in an order for $160000 worth of AAPL (4X Gearing) to trade the open? Or will IB security measures limit me to trade 2X gearing on the open only allowing me 4X gearing a fraction of a second...
Hypothetical question.
Account Value $40 000
During the day session i go long of approximately $160 000 worth of AAPL. Can I hold that stock all the way and trade it out in the closing auction to get the close price? Or will I be forced to close half of it before then? to reduce my gearing to 2X.
