Most brokers work on a best price available hypothesis. I say that because they are supposed to give you the best price and therefore if you try to order above the price they just give you a lower price.
It doesn't always work because there is also this thing called 'market etiquette' which means that if you make two orders or the price changes as you place the order. The broker cannot and will not change the market maker.
I have lots of heated convos with my brokers when they have done this to me. Tie up money and then not buy at the cheapest price or at all if it goes the other way round.
The only way to force the price up is to buy more than all available stock at that price.
