oh no it never front runs. two 3,000 share orders would go in with yours always being first. your trade is what initiates that second trade to begin with. i'm not a partner, but with all of the questions i've been getting, i did recommend that they implement hidden mimic orders on the limit buys/sells if the trader chooses. if i'm in a position, and i wanna get out @ limit asap, i wouldn't want 2X my order sitting on the inside sell. it may scare away potential buyers, and drive down the price. i visible bid/offer will always take precedence over a hidden, so the trader would have nothing to worry about. i was just using those numbers as a quick example of how it works. we could be wrong and have a trade move against us without the box. if we did slam out @ market, the box will do the same, but after you.
