The last traded price, current bid and current ask describe different things. None is a promise about your next execution.

FICTIONAL EXAMPLE · NOT LIVE PRICES
- Last trade
- $40.00
- Bid
- $39.98
- Ask
- $40.03
Displayed spread: $0.05
The last trade records a completed transaction. The bid is a buyer’s quoted price; the ask is a seller’s quoted price. Their difference is the spread. Quotes can change before an order executes. Read Investor.gov’s bid and ask definitions.
Three order types, three tradeoffs.
| Order | Instruction | What to understand |
|---|---|---|
| Market | Buy or sell at the available market price. | The execution price is not guaranteed. |
| Limit | Buy or sell at a specified price or better. | The order might not execute. |
| Stop | Become a market order when the stop price is reached. | The execution price can differ from the stop price. |
Broker policies and available instructions vary. Read Investor.gov’s order guide and your broker’s explanation before using an unfamiliar order.
The same idea can produce different results.
Two people may read the same idea at different times, see different quotes and use different orders. Available shares and changing prices can affect execution. A screenshot of someone else’s entry does not establish the price available to you. Record your actual fills when reviewing a decision.
Check your understanding.
Does a $40 last price guarantee a $40 purchase?
No. It describes an earlier transaction. The current quote and your execution can differ.
Does a limit order guarantee that you get the shares?
No. It sets a price condition. The order might remain unfilled.
Does a stop order guarantee a maximum loss?
No. Once triggered, a stop becomes a market order. Its fill can be worse than the stop price.
