When to Use a Market Order vs a Limit Order

In spot trading, the real choice is speed versus price control.

Why this lesson matters

In spot trading, the real choice is speed versus price control.

The core idea

• A market order prioritizes fast execution, but it does not lock your final fill price if the market moves while the order is filling.
• A limit order gives you a maximum acceptable price, but it may remain unfilled if the market never reaches that level.
• In thin liquidity or fast moves, the real execution price can drift away from the last price you saw on the screen.

Practical example

If BTC is moving fast, a trader may prefer a limit order near support when price control matters more than immediate entry.

Common mistakes to avoid

• Assuming the screen price is guaranteed
• Using market orders in thin order books
• Ignoring slippage risk

What to do next

It helps you choose the right order type with a clearer mindset before you send the trade.

Important caution

Volatility and liquidity can change execution versus the price you expect.
