What is Slippage in Forex? A Complete Guide for New Zealand Traders

What Exactly is Slippage?

Slippage occurs when market conditions change between the time you place an order and when it is executed. This is common in fast-moving markets, like during the release of New Zealand employment data or US non-farm payrolls. For example, if you place a buy order for USD/JPY at 110.50 but the market jumps to 110.55 before execution, you experience negative slippage of 5 pips.

Types of Slippage

There are two types: positive slippage (where you get a better price) and negative slippage (where you get a worse price). Negative slippage is more common and can eat into your profits or increase losses. New Zealand traders using market orders are most vulnerable to slippage.

Why Slippage Matters for New Zealand Traders

New Zealand traders often trade during the Asian and Pacific sessions, which have lower liquidity than London or New York sessions. Lower liquidity increases the likelihood of slippage. Additionally, many New Zealand brokers offer variable spreads, which can widen during news events, compounding slippage. For example, a trader in Auckland trying to exit a NZD/USD trade during the Reserve Bank of New Zealand (RBNZ) rate decision might see slippage of 10-20 pips.

Practical Example with USD

Imagine you are a New Zealand trader using a USD-denominated account. You want to sell 1 standard lot of EUR/USD at 1.1000. Due to a sudden USD rally, your order is filled at 1.0995. That's 5 pips of negative slippage, costing you $50 (5 pips x $10 per pip). Over many trades, slippage can add up to hundreds of dollars in extra costs.

For New Zealand traders, slippage is especially relevant because of the unique trading environment. The New Zealand dollar (NZD) is a major commodity currency, and its value is heavily influenced by dairy prices, Chinese economic data, and RBNZ policy decisions. These events can cause sudden volatility, increasing slippage risks. Additionally, many New Zealand traders use local payment methods like Bank Transfer, Skrill, and USDT to fund their trading accounts. While these methods are convenient, they do not protect against slippage—only trade execution policies do. The local financial authority (FMA) regulates brokers to ensure fair execution practices, but traders must still be vigilant. Choosing a broker with transparent slippage policies and low latency execution is critical for New Zealand retail forex traders.

1. Understand Your Broker's Execution Model
   Check if your broker uses market execution or instant execution. Market execution is more prone to slippage, but instant execution may requote. New Zealand traders should read the terms carefully.
2. Use Limit Orders Instead of Market Orders
   Limit orders guarantee a specific price or better, reducing the chance of negative slippage. This is especially useful for trading NZD/USD during volatile periods.
3. Avoid Trading During Major News Events
   News like RBNZ rate decisions or US jobs reports cause high volatility and slippage. New Zealand traders should check the economic calendar and avoid trading 30 minutes before and after such events.
4. Choose a Broker Regulated by the Local Financial Authority
   Brokers regulated by the FMA must adhere to strict execution standards, which can help minimise unfair slippage. Always verify your broker's regulatory status on the FMA website.

Compared to requotes, slippage is more common with market execution brokers. Requotes are typical of instant execution brokers and can be frustrating because they delay your trade. For New Zealand traders, market execution is generally preferred for scalping and automated trading, but it comes with slippage risk. Another related concept is 'stop-loss slippage', where your stop-loss order is executed at a worse price during a gap. This can happen overnight when the market opens after a weekend or during major news events. New Zealand traders should consider using guaranteed stop-loss orders (GSLO) for protection, though these may come with a premium.

Slippage works because of market volatility and liquidity. When you place a market order, your broker tries to fill it at the best available price. If the market moves quickly, the price may change before the order is executed. For example, a New Zealand trader places a buy order for USD/CAD at 1.2500. Simultaneously, a large sell order from a bank pushes the price down to 1.2495. The trader's order is filled at 1.2495, resulting in 5 pips of negative slippage. This is common during news events or when trading illiquid pairs like NZD/JPY during the Asian session. Brokers with high latency or poor liquidity providers may also increase slippage.

Let's look at a real example for a New Zealand trader using a USD account. You want to buy 0.1 lots (10,000 units) of GBP/USD at 1.3000. The market is volatile due to a UK inflation report. Your broker fills the order at 1.3005. That's 5 pips of negative slippage. Since 1 pip for 0.1 lots is $1, this costs you $5. Over 100 trades, that's $500 in extra costs. Conversely, if the order filled at 1.2995, you would have positive slippage of $5. To minimise negative slippage, New Zealand traders should use limit orders and trade during high liquidity hours like the London open (10 PM NZST).

The local financial authority (FMA) in New Zealand regulates forex brokers to ensure fair trading practices. While the FMA does not set specific rules about slippage, it requires brokers to act in the best interests of their clients. This means brokers must disclose their execution policies, including slippage, in a clear and transparent manner. If a New Zealand trader experiences unfair slippage, they can file a complaint with the FMA. However, the FMA does not guarantee compensation for losses due to slippage, so it is essential to choose a reputable broker. Many New Zealand traders also opt for brokers regulated by ASIC or FCA for additional protection.

• Trade During High Liquidity Hours: The best time for New Zealand traders to avoid slippage is during the London-New York overlap (10 PM to 6 AM NZST).
• Use a VPS for Automated Trading: If you use Expert Advisors (EAs), a Virtual Private Server (VPS) can reduce latency and slippage.
• Set Slippage Tolerance in Your Platform: MetaTrader 4/5 allows you to set maximum slippage in pips. Use this to control your risk.
• Monitor Economic Calendar: Avoid trading during high-impact events like RBNZ rate decisions, US CPI, or NZ employment data.
• Test with a Demo Account: Before going live, test how your broker handles slippage during volatile conditions using a demo account funded with virtual USD.

Slippage is an unavoidable part of forex trading, but New Zealand traders can manage it by understanding how it works and taking proactive steps. Choose a broker regulated by the local financial authority, use limit orders, and avoid trading during high-volatility events. Remember that slippage can affect your bottom line, especially if you trade frequently. Start by reviewing your current broker's slippage policy and consider switching to one with better execution standards.
