What is Slippage in Trading and How to Avoid It?

Picture this: You are watching a chart, waiting for the perfect breakout. The price hits your exact level at 1.1050, and you confidently smash the "Buy" button. But when you look at your open positions, your trade actually opened at 1.1055. You instantly started 5 pips in the red!

What just happened? Did your broker cheat you? Not necessarily. You just experienced one of the most frustrating, yet normal parts of trading: Slippage.

In this post, we are going to break down exactly what slippage is, why it happens, and most importantly, how you can avoid it.

What Exactly is Slippage?

Slippage is the difference between the expected price of a trade and the actual price at which the trade is executed. It happens in the milliseconds between the moment you click a button on your platform and the moment your broker’s server processes the order.

While we usually think of slippage as a bad thing, it can actually go both ways:

• Negative Slippage: When your order gets filled at a worse price than you expected (e.g., you try to buy at 100, but get filled at 102).
• Positive Slippage: When your order gets filled at a better price than you expected (e.g., you try to buy at 100, but get filled at 98).

Why Does Slippage Happen?

Slippage isn't magic, and it's rarely your broker actively hunting your stops. It usually boils down to two main market conditions:

1. High Volatility (News Events)

When major economic news drops—like the US Non-Farm Payrolls (NFP) or CPI data—the market goes crazy. Prices can jump 20 to 50 pips in a single second. If you place a market order during this chaos, the price might move significantly before your broker can find a seller to match your buy order.

2. Low Liquidity (Market Hours)

If you are trading an exotic currency pair (like USD/ZAR) or trading during quiet market hours (like the Asian session for EUR pairs), there are simply fewer buyers and sellers. Without enough liquidity, your broker has to look further up the order book to fill your trade, resulting in a worse price.

How to Avoid Slippage (4 Actionable Tips)

While you can never eliminate slippage 100%, you can drastically reduce how often it happens and how much it costs you.

• Avoid Trading During Major News Events: This is the golden rule. The easiest way to avoid massive 10-pip slippage is to step aside 15 minutes before and after massive red-folder news events like NFP or Interest Rate decisions.
• Use Limit Orders Instead of Market Orders: A market order tells your broker: "Get me in right now, at whatever the current price is." A limit order tells your broker: "Only get me in at this exact price, or better." By using limit orders, you completely eliminate negative entry slippage.
• Trade Highly Liquid Assets: Stick to major pairs like EUR/USD, GBP/USD, USD/JPY, and Gold (XAU/USD) during their active sessions (London and New York overlapping hours). High liquidity means millions of orders are waiting to match with yours.
• Choose the Right Broker: Your broker’s technology matters. A true ECN broker with deep liquidity pools and ultra-fast execution servers will experience far less slippage than a cheap, unregulated broker. For instance, brokers like Elefin invest heavily in their server infrastructure to ensure execution speeds of under a few milliseconds, keeping your fills incredibly tight.
