I'd like to use IB's Excel "sample" spreadsheet to carry out more complex conditional equity orders. However, I'm not sure if the spreadsheet is well tested, specifically with respect to submitting conditional orders. Has anyone ever used the built-in TwsDDe.xls file to submit conditional orders (or normal orders, for that matter)? Does it work fine, or is it buggy at all? Is there anything I should know before I try to use it for order submission? Any feedback would be appreciated.
