As for the so-called VIP trading channel, I have also heard of it. I don't think this is possible. Brokers use at most two sets of trading servers, one for small retail investors and one for most people. If there are many people, the speed will be slower, and the result may be a few seconds later than the actual transaction.
Another group of trading servers is dedicated to some large funds, such as funds, and even large households, to ensure that their networks are smooth, so that there will be no "many people blocking" and they can trade in the first time.
I think that's the best. Regarding the priority pending orders mentioned by several people upstairs, any brokerage firm can give priority to pending orders during non-trading hours, and after reading the link I gave you, the landlord will know that there is no difference between priority and non-priority, just accept it in advance, and the final data will not be sent until the server of the exchange is opened and accepted by you.
At best, that's what I said, using a group of servers to serve only a few people, so as to make the network smooth and the transaction delay shorter.
It is impossible to say that you hung up the bill in front of the big money, and as a result, the brokerage gave them a "VIP" channel, and as a result, they were ahead of you. This is against the trading rules. I don't think you will have this privilege anymore, otherwise the world will not be chaotic.
Speaking of grabbing the runway, the landlord really doesn't have to worry. The size of the big money itself determines that he wants to retreat quickly and grab the runway in any emergency. It is impossible to rob retail investors. Give him a dedicated server and give him enough bandwidth. At most, it saves a few seconds or even milliseconds of delay and makes a few more transactions.
