This question is addressed to anyone,preferably someone trading at a pro firm. The Nasdaq quote for whatever stock is 50.00 x 50.01 with a 1000 shares offered on Island at 50.01 with the next offer price on Island at say 51. Now i put in a buy limit order on Island for 2000 shares at a price higher than the current offer,say 50.25.I get the 1000 shares offered at 50.01 filled at 50.01 i assume.Correct me if i'm wrong. Now i have 1000 shares left to fill.My question is what happens on Level 2 with the rest of my order. Is the 1000 shares cancelled,since I can't cross the market? Does my 1000 share bid show up at 50 on Level 2,a penny below the best offer, with my order on the Island book bid at 50.25 making me eligible to get filled at 50.25 if someone on Island offers 50.25 or lower,giving the seller price improvement? Any help is appreciated?
