If you've been trading for more than a week, you've experienced slippage. You enter a trade expecting one price, and you fill at a worse one. Over time, this silent killer destroys your edge.
What Causes Slippage?
1. Market volatility
During news events, price moves faster than your broker can process the order.
2. Liquidity gaps
In less liquid pairs (NZD/CHF or exotic crosses) or during off-hours, there simply aren't enough buyers and sellers at your price.
3. Order type
Market orders always risk slippage. Limit orders don't — but they risk not filling at all.
How Much Is Slippage Costing You?
Let's do the math. If you trade 10 lots per month and experience 1 pip of average slippage on each trade:
1 pip × $10 (standard lot) × 10 trades = $100/month
That's $1,200/year — or more if you trade frequently. Many traders lose 5-10 pips on slippage alone during high-impact news.
How to Minimize Slippage
1. Trade during liquid sessions
London and New York overlap is the most liquid period.
2. Avoid news events
Simply don't trade 30 minutes before and after major economic releases.
3. Use limit orders
Instead of buying at market, place a limit order just above current price (for longs) or just below (for shorts).
4. Check your broker's execution model
ECN/STP brokers generally offer better fills than market makers.
