What happens if my order exceeds the bid or ask sizes?
You should check with your broker. I asked my broker a similar question just 2 weeks ago. With their market orders they will be filled within 3 points from the current market bid/ask. If there is any remaining it will be placed as a limit order at 3 points away from the bid/ask price. For example, if the current ask is 100 @ $1.00 followed by 500 @ $1.01, 300 @ $1.02 and 100 @ $1.03; if you were to place a buy market order for 1000 shares you would get 100 filled at $1.00, 500 filled at $1.01, 300 filled at $1.02 and 100 filled at $1.03.  If, on the other hand, you were to place a buy market order for 2000 shares you would get 100 filled at $1.00, 500 filled at $1.01, 300 filled at $1.02 and 100 filled at $1.03, with the remaining 1000 of your order being placed as a limit order at $1.03. Again, check with your broker, as they may be different in how they treat their market orders.
