How is stock price determined?
You can interpret prices in any way you wish, but the commonly quoted "price" is the last price traded. If your broker routes those orders, unlikely because they will be considered "unfair" and will probably be busted by the exchange, the only way to drive the price to the heights & lows in your example is to have an overwhelming amount of quantity relative to the order book. Your orders will hit the opposing limit orders until your quantity is exhausted, starting from the best price to the worst price. This is the functional equivalent to a market order.
