What Is Slippage in Trading, and How Can You Reduce It?

By the JustCharts team · Updated · 4 min read

Quick answer

Slippage is the difference between the price you expected when you placed an order and the price at which it actually filled. It happens when price moves or liquidity runs out between your click and the fill — most often around news, at market opens and with large orders. Slippage can be negative or positive.

Key facts

Most common

Guaranteed stop
no slippage, usually for a fee

Why slippage happens

A quote shows the best price available for a limited size. If price moves before your order arrives, or your order is larger than the volume at that price, the rest fills at the next available price. In calm markets this is usually a fraction of a pip; around big news it can be many pips.

Example

Your sell stop on EUR/USD is at 1.0800. A weak data release sends price straight from 1.0810 to 1.0780 with almost no trades in between. Your stop triggers at 1.0800 but fills at 1.0785 — 15 pips of slippage. On 1 standard lot that is about $150 more than planned.

Frequently asked questions

Is slippage the broker cheating?

Not usually — it is a normal result of fast markets and limited liquidity. Regulated brokers should also pass on positive slippage when price moves in your favour.

Do limit orders have slippage?

Limit orders cannot fill at a worse price than your limit, but they may not fill at all.

Why did my stop-loss close at a worse price?

A stop becomes a market order once triggered. If price jumped past your level, it filled at the next available price.
