Fixed spread

What is Fixed spread in forex and CFD trading

Fixed spread refers to a dealing model where the difference between the Bid price and the Ask price for a given instrument remains constant, irrespective of current market volatility or liquidity conditions. A Fixed spread matters for real trading decisions because it provides absolute cost certainty, allowing traders, particularly those using smaller accounts or specific strategies, to calculate their transaction costs precisely before execution. A trader can verify a Fixed spread by checking the broker’s account terms and by observing the Spread value in the Market Watch window during periods of market stress, where the value should not change.

Key facts about Fixed spread

• Cost Certainty: The primary benefit of a Fixed spread is the predictability of the transaction cost, simplifying risk and PnL calculations.
• Provider Model: Fixed spread models are typically offered by Market Maker brokers who manage their risk internally and can absorb the cost fluctuations.
• Quoted Value: The size of a Fixed spread is generally wider than the average variable spread for the same instrument during highly liquid times, often 1.5 to 2.5 pips for EUR/USD.
• Execution Risk: While the spread is fixed, the broker may reserve the right to re-quote prices or reject orders, especially during extreme volatility, to manage the increased risk they incur by maintaining the fixed cost.
• Stop Loss Placement: The predictable nature of the Fixed spread simplifies placing tight stop-loss and take-profit orders, as the distance from the market price to the breakeven point is known.
• No Commission: Accounts offering a Fixed spread often do not charge a separate commission, as the broker’s compensation is built entirely into the wide Spread.

How Fixed spread works in forex and CFD trading

The Fixed spread model functions because the broker acts as the counterparty to the trade, assuming the risk that market spreads may temporarily widen beyond the fixed cost they quote to the client.

The process involves these operational steps:

1. Broker Risk Management: The Market Maker broker determines an average expected market spread for an instrument, then adds a safety buffer and their profit margin to set the Fixed spread.
2. Quote Derivation: The Bid price and Ask price are generated such that Ask Price – Bid Price = Fixed Spread, ensuring the difference remains constant.
3. Price Movement: As the underlying interbank price moves, the broker adjusts both the Bid and Ask prices simultaneously to maintain the fixed difference.
4. Order Execution: Orders are generally filled at the quoted Fixed spread prices, though some brokers may apply an execution clause allowing for re-quotes during low liquidity or high volatility.

Example of Fixed spread with a real trade

This example demonstrates how a Fixed spread ensures the cost remains constant, simplifying cost analysis.

Instrument: EUR/USD Fixed spread: 1.8 pips Position size: 1 standard lot (100,000 units) Pip Value: $10/pip

Result: In both normal and volatile conditions, the transaction cost remains $18.00, offering complete cost predictability for the trader.

How Fixed spread affects your cost and risk

The Fixed spread affects cost and risk by replacing uncertainty with predictability, though this certainty comes at the expense of potentially paying more than the average cost during liquid periods.

Fixed spread compared with related concepts

Fixed spread vs Variable spread

A Fixed spread offers predictable transaction costs that do not change with market conditions, which is beneficial during major news events, whereas a Variable spread fluctuates based on market liquidity, generally offering tighter average costs but carrying the risk of significant widening.

Fixed spread vs Commission-based pricing

The cost in a Fixed spread model is entirely included within the Bid/Ask differential, often resulting in a wider spread, whereas Commission-based pricing uses a near-zero raw spread supplemented by a separate, per-lot commission fee, which is often cheaper overall for high-volume traders.

Broker differences in Fixed spread across the industry

The availability and guarantee of a Fixed spread depend heavily on the broker’s underlying execution model, with Market Makers being the primary providers of this service.

How to verify Fixed spread on your trading platform

To mechanically verify a Fixed spread on a trading platform like MetaTrader 4 (MT4), follow these steps:

1. Log into Fixed Spread Account: Log into the account designated as offering a Fixed spread (usually a Standard or Fixed account type).
2. Display Spread Column: Open the Market Watch window and locate the instrument, ensuring the Spread column is displayed.
3. Monitor Spread Value: Note the Spread value and monitor it for at least 30 minutes across different market conditions, including a minor news event if possible.
4. Manual Calculation Check: Calculate the spread manually: Ask Price – Bid Price, using the quote displayed in the New Order ticket.
5. Consult Broker Documentation: Check the broker’s website Product Specification or Account Terms document to confirm the guaranteed Fixed spread value for that specific instrument.
6. Compare Volatility Conditions: Compare the Spread value observed during a quiet market with the value observed during high volatility, such as a major data release.
7. Sanity check: If the Spread value remains constant in points/pips during both quiet and volatile periods, it is functioning as a Fixed spread.
