a trader showed me some fills in large blue chip bank stocks that go out several decimal places beyond a penny. ie bot 5000 C price 4.031125. i thought stocks traded in lowest increment of a penny ie hundereths place. what's with these fills? thanks in advance.
RK I did a search and came up with sub penny quotes on stocks above $1 are NOT allowed. but sub penny fills are. AND what about getting slightly better fills? are you getting an adjustment in your favor by system that filled it? thanks in advance.

Among the first links from the Web search Mr Bob suggested is material from ET site sponsor Don Bright. You might start there. Again, please search ET, and the Web. All of this is well understood and explained in many places.
