I think you misread my post and intention. All I said is that it's obviously not as straightforward as you think when most other brokers do in fact not charge non display fees. I looked up your past posts and you seemed to be one of the very few or only one insisting on non display fees having to be charged for those who trade automated algorithms. I guess we can both agree that Interactive Brokers would not violate or deceive exchanges given their transparency and public exposure. So, it seems apparent that those non display fees do not apply to everyone who trades automated strategies. That was my point. I did not mean to personally attack you and I don't think I did. Do those non display fees exist? Yes surely they do, but it is not clear whom they apply to.
Here is the link to standard blpapi documentation of Bloomberg. They do provide live real time streaming data via their excel api, c#, python and c++ APIs. I have used the api myself in the past.
