This hotkey buy or sells me the shares at outside the bid/ask to a max of what I set it on. For example, today I sold 100 shares of DPW in premarket with a price offset of -35 cents and it executed at 25 cents below the current bid on the level 2. This happen numerous times so I left it at 1 cent. Is this suppose to happen during extended hours or did the market makers or broker play dirty? I am using tradezero.
There’s no NBBO protection pre/post markets. Which exchange did it fill at? Also, when using offset, good question to ask is - is the offset taken off the prices seen in GUI client or the broker’s servers? These two may diverge significantly due to latency.
