Let's say you want to buy X shares of an ETF on Fidelity using the market order option, and you only have enough cash to purchase those X shares at the current trading price
When the market opens, there's a possibility that the price surges, meaning you can no longer afford to purchase all X shares of the ETF
Does Fidelity fulfill as many share purchases as possible at the constantly changing trading price until your available cash to trade is no longer enough to purchase another share? Or is the entire order canceled if the (trading price) multiplied by (X shares desired) always exceeds your available cash to trade for the duration of the trading day?
And does the behavior vary from brokerage to brokerage?
