Execution Quality: The Sixty Seconds Around a Scheduled Economic Release

At 13:30 GMT on the first Friday of each month, the US Bureau of Labor Statistics releases its Employment Situation Summary, commonly known as Non-Farm Payrolls (NFP). In the microseconds following this announcement, the EUR/USD pair, a relatively stable major during normal hours, can move 50 to 100 pips in either direction. This rapid price discovery is not an isolated phenomenon; similar, if less dramatic, movements accompany interest rate decisions, CPI data, and central bank statements from major economies.

What differentiates these moments from typical trading hours is the sudden, drastic re-pricing of assets as market participants digest new information. Traders accustomed to consistent bid-ask spreads and near-instant order fills often find the sixty seconds around such a release to be an entirely different trading environment. The observable price on their platform might deviate significantly from the price at which their order is actually filled, if it is filled at all.

This immediate period is characterised by a severe contraction in available liquidity. Large institutional players, often responsible for providing the bulk of market depth, tend to withdraw their passive orders from the electronic order books just prior to the release. They do this to avoid taking significant losses if the news deviates sharply from expectations. The remaining orders are often smaller, more aggressive, and less numerous, creating an environment where even modest order sizes can cause substantial price shifts. This is the underlying mechanism for the 'fast market' conditions brokers describe.

The manner in which a broker processes client orders during periods of high volatility is heavily influenced by its internal business model. Broadly, brokers fall into two categories: Market Makers (MM) and Electronic Communication Network/Straight Through Processing (ECN/STP) brokers.

Market Maker brokers typically operate a dealing desk and take the opposite side of their clients' trades. This means that if a client buys, the broker sells from their own inventory, and vice-versa. While this can offer fixed spreads and guaranteed fills during normal market conditions, it introduces a potential conflict of interest during news events. When the market moves sharply against the broker's positions, they face the choice of filling orders at unfavourable prices, issuing re-quotes, or rejecting orders outright. The latter two options are common strategies to manage their own risk, often to the client's detriment. For example, XM, while offering various benefits like promotions, operates with a dealing desk model.

ECN/STP brokers aim to connect client orders directly to external liquidity providers (tier-1 banks, other brokers, hedge funds). They typically charge a commission per trade and widen spreads during volatile periods as their underlying liquidity providers do. Since they do not take the opposite side of client trades, their incentive is aligned with the client's trading volume, not their losses. During news, an ECN/STP broker will pass on the prevailing market price from their liquidity pool. Slippage is therefore expected and unavoidable, reflecting the true market conditions, but re-quotes are rare because the broker is not attempting to 'make' a price. Brokers like Pepperstone, which advertises fast execution, and IC Markets typically operate on an ECN/STP model.

Slippage occurs when an order is executed at a price different from the one requested by the trader. During the sixty seconds around a major economic release, slippage is not an anomaly; it is an expected characteristic of a 'fast market'. This happens because the price can move significantly between the moment a trader clicks 'buy' or 'sell' and the moment the broker's system, and subsequently the liquidity provider's system, processes the order.

There are two forms of slippage: positive and negative. Positive slippage occurs when an order is filled at a better price than requested, while negative slippage results in a worse price. For example, if a trader places a buy order for EUR/USD at 1.0850, and the order is filled at 1.0848, that is 2 pips of positive slippage. If it's filled at 1.0852, that's 2 pips of negative slippage. Critically, stop-loss orders are also susceptible to slippage, meaning a trader's maximum intended loss can be exceeded. This is a vital point often overlooked by those new to trading high-impact news.

Some brokers offer 'guaranteed stop-loss' orders, but these typically come with a higher spread or a premium. For instance, a broker might guarantee a stop-loss at a certain price, but only if the market moves against the trade for a specified number of pips, or they might charge a fee. The availability and terms of such guarantees should be thoroughly investigated. Otherwise, assume that in a genuinely fast market, your stop-loss order will be treated as a market order once triggered and may experience slippage.

When a Market Maker broker receives an order during a period of high volatility, the price at which they can fill that order might have changed significantly in the brief intervening milliseconds. To protect their own capital, they may offer a 're-quote'. A re-quote is a notification that the requested price is no longer available, and a new, usually less favourable, price is offered. The trader then has a limited window, often 3-5 seconds, to accept or reject this new price. If rejected, or if the time limit expires, the order is cancelled.

Order rejection is an even more definitive outcome. This occurs when the broker simply cannot fill the order at any reasonable price, or when their internal risk management parameters are exceeded. For a retail trader attempting to capitalise on a fast market move, a re-quote or rejection means lost opportunity and frustration. In practice, the desk will ask twice. This is particularly common with Market Maker brokers during major news events where price action is chaotic and unpredictable.

While some might argue these are necessary risk management tools for the broker, for the trader, they represent a significant barrier to effective trading strategy during critical moments. A broker's frequent use of re-quotes or rejections during anticipated volatility should be a red flag regarding their execution quality in such conditions.

In the context of high-frequency trading and news-based strategies, latency – the delay between an action and a response – is a primary determinant of execution quality. Even a few milliseconds can mean the difference between a profitable trade and a significant loss when prices are moving tens of pips per second. Brokers invest heavily in low-latency infrastructure, including colocation of servers with major liquidity providers and fast network connections.

A broker's server location relative to its liquidity providers and the trader's terminal can introduce significant latency. For instance, a trader in London using a broker with servers in New York will experience greater latency than one using a broker with servers in London, assuming all other factors are equal. This is the part most guides skip, often focusing solely on spreads. A broker that advertises 'fast execution' but hosts its servers in a geographically distant data centre from its primary liquidity partners or target client base is effectively offering a diminished service in volatile conditions.

Many prominent brokers, such as OANDA and FOREX.com, maintain multiple data centres globally to reduce latency for their diverse client base. This geographical distribution helps mitigate some latency issues, but during moments of extreme volatility, even the fastest connections can struggle to keep up with the rate of price changes and order flow. This inherent physical limitation means that zero latency is an impossibility, and traders must account for this in their expectations.

Regulatory bodies play a role in attempting to ensure fair execution practices, though their powers are often focused on transparency rather than dictating specific outcomes during fast markets. Under ESMA's product intervention on CFDs, for example, leverage for retail clients is capped at 1:30 for major currency pairs. This measure aims to protect retail traders from excessive risk, implicitly acknowledging the amplified potential for losses during volatile periods where slippage can magnify initial exposure.

Regulators like the FCA in the UK or ASIC in Australia require brokers to have and adhere to 'best execution' policies. This means brokers must take all reasonable steps to obtain the best possible result for their clients, considering price, costs, speed, likelihood of execution and settlement, size, nature, or any other consideration relevant to the execution of the order. However, 'best execution' does not mean 'no slippage' or 'no re-quotes' in volatile markets; it means the broker must demonstrate they had an effective process in place to achieve the best available terms.

It is crucial for traders to review a broker's execution policy document, which is typically available on their website. This document outlines how the broker handles orders, including during periods of low liquidity or high volatility. While the language can be dense, it often contains clauses detailing how slippage is handled and under what conditions re-quotes or rejections may occur. For instance, FxPro's regulatory adherence means they must disclose such policies.

One of the most immediate and visible effects of a scheduled economic release is the dramatic widening of the bid-ask spread. Under normal market conditions, the spread on a major pair like EUR/USD might be 0.5 to 1.5 pips. During the minute leading up to, and especially following, a significant news announcement, this spread can expand to 10, 20, or even 50 pips or more. This widening is a direct consequence of the sudden reduction in liquidity and the increased risk aversion among remaining market participants.

For traders, a widened spread means that the cost of entering or exiting a trade increases substantially. For example, if you place a market order to buy EUR/USD when the spread is 20 pips, you are immediately 20 pips in the red upon execution, assuming the price doesn't move further. This makes short-term, news-based strategies particularly challenging and often unprofitable, as the initial cost of the trade can consume a significant portion of any immediate price movement.

Some brokers might advertise 'zero spread accounts', but these almost universally come with a commission per lot traded. Even these accounts will experience spread widening during news, as the 'zero spread' typically refers to the interbank spread passed through by the ECN, which itself widens. It is a common misconception that 'zero spread' means immunity from news volatility. Exness, for example, offers accounts with 'zero spreads' but it is imperative to understand the real conditions.

A client's perception of market price, presented on their trading terminal, is the culmination of a complex, multi-stage journey. This journey begins with liquidity providers (LPs) – typically Tier-1 banks and major Electronic Communication Networks (ECNs) such as EBS or Refinitiv – who stream bid and ask prices. These raw feeds, often exceeding hundreds of updates per second, arrive at the broker's infrastructure. Brokers aggregate these multiple feeds, normalising them for consistency and filtering out anomalous quotes that might indicate latency arbitrage attempts or 'fat finger' errors. This aggregation process is crucial; a broker with access to a wider array of quality LPs can theoretically offer more competitive pricing and deeper liquidity.

However, the price displayed on the terminal is rarely the raw interbank rate. The broker’s internal matching engine processes these aggregated quotes. Market Maker brokers, for instance, often internalise orders and may introduce a modest mark-up or spread adjustment, particularly during volatile periods. Even ECN/STP brokers, while aiming for direct market access, must manage their own connections and internal routing. A significant factor in this process is 'last look' liquidity. Many institutional LPs offer prices on a 'last look' basis, meaning they reserve the right to decline or re-quote an order if the price has moved during the short time it takes for the order to reach their systems. For a retail trader, this mechanism can manifest as a re-quote or increased slippage, especially when market conditions shift rapidly around news announcements.

The final leg of this journey is the transmission from the broker's server to the client's trading terminal. This involves internet latency, which can vary significantly based on the client's geographic location relative to the broker's data centres, their internet service provider, and the quality of their local network hardware. Whilst individual components may seem trivial, their cumulative effect can be substantial, as evidenced in the typical breakdown of latency contributions below. A delay of merely ten milliseconds can be the difference between filling an order at the desired price and receiving a re-quote or experiencing negative slippage during a Non-Farm Payroll release.

Diligent traders must go beyond anecdotal experience and actively analyse their broker’s execution performance, particularly during critical news events. Most reputable brokers provide detailed trade confirmations or execution reports. These are not merely receipts; they are forensic documents. Key data points to examine include the 'requested price', the 'executed price', the 'order submission timestamp', and the 'order execution timestamp'. The discrepancy between the requested and executed price reveals slippage, which should then be quantified in pips.

A proper post-trade audit involves systematically compiling this data. Consider a hypothetical scenario where a trader executes fifty orders during the sixty seconds surrounding a major release. One should tally the instances of positive slippage (execution better than requested), negative slippage (execution worse than requested), and zero slippage. Crucially, the aggregate pip value for both positive and negative slippage should be calculated. An uneven distribution, where negative slippage consistently outweighs positive, warrants further investigation. For example, if a broker consistently delivers two pips of negative slippage on average but only one pip of positive slippage, this suggests a systemic bias that might erode profitability over time. Regulators such as the FCA require brokers to demonstrate 'best execution', which involves regularly assessing the quality of execution obtained for clients.

Another metric to observe is the 'time in market' for an order – the duration between submission and execution. Whilst minor delays are inevitable, consistent execution times exceeding, say, 500 milliseconds for market orders during high-volatility periods can indicate systemic issues with the broker's infrastructure or liquidity access. One might also cross-reference the executed prices against reputable historical data feeds (e.g., from an independent data vendor) for the precise timestamp of execution. While not a definitive measure due to differing data sources, significant deviations could flag concerns. Ultimately, this meticulous review offers objective evidence of execution quality, informing decisions about broker selection and news trading strategies.

Given the complexities of execution quality around news releases, traders must adopt a considered approach. Firstly, a direct market entry at the exact moment of a release is often a low-probability endeavour. The combination of unpredictable slippage, potential re-quotes, and dramatically widened spreads makes consistent profitability extremely difficult for retail traders lacking institutional-grade direct market access.

Consider using pending orders placed a few seconds before the release, but understand that these too are subject to slippage. A 'buy stop' order, for instance, triggers at a certain price but will be filled at the best available price beyond that point, which might be significantly higher in a fast market. A 'sell limit' order might not be filled at all if the market moves too quickly past the desired price without sufficient liquidity.

Some traders choose to avoid trading the immediate aftermath of high-impact news altogether, opting instead to wait for the initial volatility to subside and for clearer market direction to emerge. This involves monitoring the market for 5-15 minutes after the announcement, allowing spreads to normalise and order books to rebuild. This strategy foregoes the initial explosive move but offers a significantly more predictable trading environment. It may not be as exciting, but it often proves more fiscally prudent. Understand that the sixty seconds around a major release are not a normal trading environment, and adjust your expectations and strategy accordingly.
