Market orders vs. limit orders
When you buy or sell, you choose the order type. Pick the wrong one on a volatile stock and you can lose real money on the spread.
Written for plain-English understanding by Joseph Citizen. Why I built this →
When you place a trade, your brokerage asks what kind of order you want. The two basic ones are market orders and limit orders. Knowing the difference will save you from accidentally overpaying.
Market order
'Buy this, right now, at whatever the next available price is.' The trade happens almost instantly. Simple, fast, and the right choice for big liquid stocks like Apple or an S&P 500 ETF, where the price barely moves between bid and ask.
Limit order
'Buy this, but only if the price is at or below my limit.' You set the maximum you'll pay. The trade only fills if a seller meets your price. Slower, but you control the price.
When the choice matters
On thinly traded stocks — small companies, low-volume ETFs, anything outside normal market hours — the gap between bid and ask can be wide. A market order could fill at a much worse price than you expected. Limit orders protect you from this.
Keep the momentum going.
