Understand Slippage in MT5 CFD Trading - Practical Guide

Slippage is an unavoidable reality for traders, especially when using the MetaTrader 5 platform. It refers to the difference between the price you expected when opening a position and the actual price at which your order is filled. This phenomenon may seem insignificant in a single trade, but cumulatively it can impact your profitability. Understanding its causes and mechanisms is essential for any trader who wants to operate confidently on MT5.

Why Slippage Occurs in Trading Operations

Slippage arises from various interconnected factors. Delays in order execution, rapid market movements, and insufficient volume at the desired price level are the main causes. During periods of high volatility—such as during major economic announcements or market openings—the likelihood of experiencing slippage increases significantly.

On the MT5 platform, there is a specific mechanism that amplifies the relevance of slippage: different types of orders are converted into market orders once triggered. This means that regardless of the initial order type you set—if it is triggered by the established criteria—the system will execute it as an instant market order, exposing it to the associated slippage risks.

How the Three Types of Orders Suffer Slippage on MT5

Limit Orders: Target Price Without Guarantee of Execution

When you set a limit order, your goal is to specify a particular entry price. Suppose you place a buy limit order for EURJPY at $90.000. When the market reaches this level, the order is triggered. However, on MT5, the system converts it into a market order. If demand is intense at that moment, the best available price might be $90.050, resulting in a slippage of $50 against your expectations.

This scenario reveals a critical point: limit orders offer theoretical protection but do not guarantee execution without slippage once triggered.

Stop Orders: Vulnerable Protection in Moving Markets

Stop orders act as a protective mechanism, triggering when a critical price is reached. However, in fast-moving markets, slippage can be severe. Imagine you set a sell stop for XAUUSD (gold) at $2,600 as a loss protection. A sharp decline occurs, and your stop is triggered, but due to reduced liquidity at that price level, the actual execution occurs at $2,595. The resulting slippage is $5 against you.

In extreme scenarios, during market crises or traumatic news, slippage on stop orders can be even greater.

Market Orders: Immediate Execution with Inherent Risk

Market orders are filled instantly at the best available price at the moment. However, in volatile environments, the quote can move rapidly between the time you send the order and when it is actually executed. A practical example: you send a buy order for NAS100 (Nasdaq 100 index) at a quote of 21,200. By the time the system processes the order, the price has moved to 21,205, resulting in a slippage of $5.

Practical Strategies to Reduce Slippage in Your Trades

Reducing the impact of slippage requires planning and discipline. First, focus your trades during high-liquidity hours, when transaction volume is higher and the bid-ask spread narrows. Second, avoid placing orders during critical periods—such as interest rate announcements, employment data releases, or official statements—when volatility spikes and slippage increases.

Additionally, consider using price limits when possible, and stay attentive to the specific conditions of MT5. Understanding that all your orders will be executed as market orders once triggered allows you to set realistic strategies, anticipating implicit costs.

Trading on MT5 demands that you not only understand slippage theoretically but also incorporate it as a constant risk variable in your operational planning.
