Seems close to this thread?? /g/twsapi/topic/80863099#46628
Look to me that the link to IB article is broken, try search with keyword/sentence is "Order Efficiency Ratio" or "Optimizing Order Efficiency"
IB require some "efficiency" in the management of your orders, IB even give you report tool to analyze your account order efficiency (or lack thereof).
This is a Pandora-box issue because there are a lot of tradeoff behind it, many of theses tradeoffs require strategical choices: Speed versus flexibility versus safety when lack of liquidity etc ...
Suggestion: study IB offers first, . They do a lot for you and are well integrated.
