Limit Order vs. Market Order — Comparison of Order Types

Definitions

Market order

A buy or sell order at the best available price at the given moment. Execution is immediate (if there's liquidity), but you don't control the exact price.

Limit order

A buy or sell order at a specified price or better. A buy limit order at 95 PLN means: "buy, but not more expensive than 95 PLN". A sell limit order at 105 PLN: "sell, but not cheaper than 105 PLN".

Comparison

When to use market order?

• You're buying a large, liquid ETF (e.g., VWCE, SPY) — spread is minimal
• You want to quickly enter or exit a position
• Exact price isn't critical (0.1% difference in DCA is irrelevant)
• Market is open and calm (avoid market orders at session opening)

When to use limit order?

• You're buying a less liquid instrument (small companies, exotic ETFs)
• Spread is wide (>0.5%)
• You have a specific target price — e.g., want to buy only after a correction
• You're trading a larger amount — limit protects against slippage
• Market is unstable (high volatility, sudden movements)

Practical example

ETF costs 100 PLN (bid: 99.80, ask: 100.20):

• Buy market order: you buy at ~100.20 PLN (ask)
• Buy limit order 99.90 PLN: order waits. If price drops to 99.90 — you buy. If not — order expires

For a 1,000 PLN purchase, the difference is ~3 PLN. For 100,000 PLN — that's 300 PLN on one transaction.

Stop-loss and stop-limit

• Stop-loss: "sell at market price when price drops to X" — guarantees exit, but not price
• Stop-limit: "sell with limit Y when price drops to X" — you control price, but order may not execute during a sharp drop
