I am looking at using IB to place limit order during the opening auction and have a couple, of hopefully simple questions:
1. From what metric does IB use to calculate the maximum acceptable for a limit order e.g. Does it use previous days close + 5% as the maximum acceptable for a limit order, or does it use the indicative auction price + 5%?
2. What % of the price does IB allow for the limit? i.e. is it a fixed 5%, 10%?
3. If you enter a limit order that is higher than the defined %, what happens to it? does it still get placed?
From my post above (haven't actually tried switching the limits off yet):
"It looks as though you can turn this off. For the API it's in Configure->API->Precautions, and for the GUI it's Configure->Presets->Precautionary settings. However, if that's the case then it makes the IB message about the cap/floor look silly, because the message says that the exchange requires the cap/floor to be set..."
