>Your order can legally be “front run” by the lead or designated market maker who receives priority trade matching, bypassing the normal FIFO queue. Not all exchanges do this.

Unless you're thinking of some obscure exchange in a tiny market, this is just untrue in the U.S., Europe, Canada, and APAC. There are no exchanges where market makers get any kind of priority to bypass the FIFO queue.

Nope, several large, active, and liquid markets in the US.

Legally it’s not named “bypass the FIFO queue”. That would be dumb.

In practice, it goes by politically correct names such as “designated market maker fill” or “institutional order prioritization” or “leveling round”.
