Learn Trading Costs Execution Quality
Execution Quality
Execution is the “behind the scenes” part of trading: how your order actually gets filled. Two brokers can show similar spreads, but you can still get very different results if one has more slippage, rejections, or slower fills—especially in fast markets.

Forex execution quality
Execution is how your order gets filled. It decides your real cost on top of spreads—especially in fast markets.
- Best case: small slippage + occasional price improvement
- Red flags: frequent re-quotes, rejections, one-way slippage
- Most sensitive moments: news, rollover, Sunday open
Tight spreads mean little if your fills are consistently worse than expected.
Execution basics
- Market orders: prioritize getting filled fast — but you accept price changes (slippage).
- Limit orders: prioritize price control — but you may not get filled.
- Stop orders: trigger first, then behave like a market order in fast moves (can slip).
- Requotes / rejections: some brokers may refuse or re-price orders when markets move quickly.
What good execution looks like (quick checklist)
- Fills are consistent: normal markets = small slippage, not random large jumps.
- You sometimes get price improvement: not only negative slippage.
- Few rejections: orders don’t fail exactly when volatility increases.
- Stops behave reasonably: tight stops aren’t “mysteriously” hit by repeated spread spikes.
How to test execution in 10 trades
- Record expected price: the price you clicked (or the trigger level for stops).
- Record fill price: the actual executed price from history.
- Tag the context: liquid session vs thin hours, news, rollover, Sunday open.
- Look for bias: if you never see positive slippage, that’s a red flag.
