Investing term
What is Limit order?
Buy only at $X or better — price-protected, but may not fill.
A limit order tells your broker to buy or sell only at a specified price or better, giving you price protection at the cost of certainty. A buy limit fills at your price or lower; a sell limit at your price or higher. You control the price you'll accept, but not whether the trade happens.
The trade-off is simple: if the market never reaches your price, the order just doesn't execute. That's protection against a bad fill, but no guarantee you'll trade at all. Limit orders shine on thinly traded securities and fast markets, where a market order might fill at a surprisingly poor price — the limit caps the damage by refusing anything worse than your number.
A limit order fills only at your price or better — protection from a bad fill, at the risk of not trading at all. A buy limit at $50 waits until the price drops to $50.
For example
You set a buy limit at $50; the order fills only if the stock drops to $50 or below — never paying more, but possibly never filling.

Limit orders matter because they hand you control over price, which is exactly what you lose with a market order. On illiquid stocks, in volatile moments, or for any trade where a few cents matter, a limit order is the difference between a known price and a nasty surprise. The cost — the risk of not filling — is usually worth paying for anything other than a large, liquid stock where the spread is trivial.
⚠ Setting a limit and missing the trade
A limit order protects your price but can leave you on the sidelines if the market never touches it — and chasing a fill by nudging the limit repeatedly can cost more than a market order would have. For a long-term buy of a liquid fund, obsessing over a few cents with a limit that never fills can mean missing the investment entirely.
