What is Slippage in Forex? A Complete Guide for Taiwan Traders (2026)

What Causes Slippage in Forex?

Slippage happens when market volatility or low liquidity prevents your order from being filled at the exact price you requested. For example, if you place a market order to buy USD/TWD at 30.50, but by the time the order reaches the broker, the price has moved to 30.55. Your order is filled at 30.55, resulting in a 5-pip negative slippage. In fast-moving markets like during US Non-Farm Payrolls or Federal Reserve announcements, slippage can be much larger, sometimes 10-20 pips or more.

Positive vs Negative Slippage

Not all slippage is bad. Positive slippage occurs when your order is filled at a better price than expected. For instance, if you want to sell USD/TWD at 30.50, but the market moves in your favor and fills you at 30.55, you gain 5 pips. However, negative slippage is more common and can hurt your trading results. Many Taiwan traders focus on avoiding negative slippage by using limit orders and avoiding high-impact news releases.

How Slippage Affects Your Trading in USD

If you trade a standard lot (100,000 units) of USD/TWD, a 5-pip negative slippage costs you approximately $50 USD. Over many trades, this adds up. For retail traders in Taiwan, even small slippage can turn a winning strategy into a losing one. That is why it is important to factor slippage into your risk management plan and choose brokers with fast execution and low slippage rates.

For Taiwan traders, slippage is particularly relevant when trading during the Asian session, where liquidity can be lower compared to London or New York hours. Many local brokers offer ECN or STP execution, which can reduce slippage but does not eliminate it. When funding your trading account via Bank Transfer, Skrill, or USDT, you should be aware that slippage can affect your margin requirements. For example, if you deposit $1,000 USD via Skrill and experience a 10-pip slippage on a trade, your available margin drops faster than expected. The local financial authority in Taiwan does not cap slippage, but it requires brokers to disclose their execution policies. Always check your broker’s slippage policy before trading.

1. Choose a reliable broker
   Select a broker regulated by the local financial authority in Taiwan that offers transparent slippage statistics and fast execution speeds.
2. Use limit orders
   Instead of market orders, use limit orders to control the maximum price you are willing to accept, reducing the chance of negative slippage.
3. Trade during high liquidity hours
   Focus on trading during the London-New York overlap (20:00-00:00 Taiwan time) when spreads are tighter and slippage is less likely.
4. Avoid high-impact news events
   Stay away from trading 30 minutes before and after major economic releases like US Non-Farm Payrolls or Fed interest rate decisions to minimize slippage risk.

For Taiwan traders, slippage is different from requotes. Requotes happen when a broker cannot fill your order and asks if you want a new price. Slippage is automatic. Many ECN brokers offer no requotes but still have slippage. Spread widening is another related concept where the bid-ask spread increases, often causing slippage. Understanding these differences helps you choose the right execution model for your trading style.

Slippage works through the order execution process. When you place a market order, your broker sends it to the liquidity provider. If the price moves before the order is filled, your order is executed at the next available price. For Taiwan traders using USD accounts, this means if you try to buy USD/TWD at 30.50 but the market spikes to 30.55, you get filled at 30.55. The opposite can happen if the market moves against you. Slippage is more common during news releases, market openings, and when trading less liquid pairs.

Example 1: You want to buy 1 lot of USD/TWD at 30.50 using a market order. The current ask is 30.50, but due to a sudden USD strength, the price jumps to 30.53. Your order is filled at 30.53, causing a 3-pip negative slippage. This costs you $30 USD. Example 2: You place a sell limit order on USD/TWD at 30.60. The market reaches 30.60 but then drops to 30.55. Your order is filled at 30.60, so no slippage occurs. Limit orders give you price control.

The local financial authority in Taiwan oversees forex brokers operating in the country, ensuring they follow fair execution practices. While the authority does not set a maximum slippage limit, it requires brokers to disclose their order execution policies and any slippage statistics. For Taiwan traders, this means you have the right to see how your orders are executed. Always verify that your broker is registered with the local financial authority and read their terms of service carefully.

• Set slippage tolerance: Many platforms like MetaTrader 4 allow you to set a maximum slippage in pips. Use this feature to limit negative slippage to 3-5 pips.
• Use pending orders: Pending orders (buy limit, sell limit) are less affected by slippage because they only execute at your specified price or better.
• Check broker speed: Use demo accounts to test your broker’s execution speed during different market conditions before trading real money.
• Monitor news calendar: Keep a forex news calendar handy and avoid trading during high-impact events to reduce slippage risk.
• Diversify trading hours: If you trade USD/TWD, remember that the Taiwan dollar is most liquid during Asian hours, but slippage can still occur during unexpected events.

Slippage is an unavoidable part of forex trading, but with the right knowledge and tools, you can minimize its impact on your trading results. For Taiwan traders, choosing a regulated broker, using limit orders, and trading during high liquidity hours are key steps to managing slippage. Start by reviewing your current broker’s slippage policy and consider testing a demo account to see how slippage affects your trades. Ready to trade smarter? Compare brokers on comparebroker.io today.
