Market vs Limit Orders

A market order says 'buy/sell now at the best available price'. It executes fast but you accept whatever the price moves to in that moment.

A limit order says 'buy at $X or lower' (or sell at $X or higher). It guarantees price but not execution — the market may never reach your limit.

Pros use limits for size and liquidity-thin names; market orders for blue chips and small lots where slippage is tiny.
