How did you measure broker execution speed?

We submitted 500 market orders per broker (12,500 total across 25 brokers) on EUR/USD during London and New York sessions over 10 trading days. Each order was a 0.01 lot market order. We measured the time from order submission to fill confirmation using each platform's API timestamp, cross-referenced with our own client-side timestamps. Orders were distributed evenly across sessions to avoid time-of-day bias.

What is the difference between median and P95 latency?

Median latency is the middle value: half of all orders filled faster, half slower. It represents the typical execution speed. P95 (95th percentile) latency means 95% of orders filled faster than this value. P95 captures the "worst reasonable case" — if your P95 is 120ms, only 5% of orders take longer than 120ms. For scalpers, P95 matters more than median because a single slow fill during a fast-moving market can turn a winning trade into a loser.

Does platform choice affect execution speed?

Yes, measurably. Across brokers that support multiple platforms, cTrader consistently delivered the lowest median latency (6-10% faster than MT5, 12-18% faster than MT4). TradingView integration speeds were comparable to MT5. MT4, as the oldest protocol, showed the highest latency. However, the difference between platforms at the same broker (typically 5-15ms) is smaller than the difference between brokers on the same platform (which can exceed 50ms).

What counts as positive, zero, and negative slippage?

Positive slippage means your order filled at a better price than requested — you paid less on a buy or received more on a sell. Zero slippage means the fill price exactly matched the requested price. Negative slippage means the fill price was worse than requested. A small amount of negative slippage is normal during fast-moving markets. What matters is the distribution: a broker with 60%+ zero slippage and under 25% negative slippage is performing well by industry standards.

Why do some brokers have higher requote rates?

Requotes occur when the price moves between order submission and processing. Brokers using a dealing-desk (market maker) model are more likely to requote because they need to decide whether to accept the order at the requested price. ECN/STP brokers with direct market access typically have near-zero requote rates because orders are filled at the best available market price. Our data confirms this: all brokers with requote rates above 2% use a market-maker or hybrid execution model.

Is faster execution always better?

For scalpers and high-frequency strategies, sub-40ms execution is a meaningful advantage. For swing traders holding positions for hours or days, the difference between 30ms and 80ms execution is irrelevant. What matters more universally is fill rate (above 99%) and slippage distribution (majority zero or positive). A broker with 50ms median latency and 99.8% fill rate is functionally better for most traders than one with 25ms median latency and 98% fill rate.

How does execution speed affect trading costs?

Slow execution introduces implicit costs through slippage. In our test, the average negative slippage across all brokers was 0.3-0.7 pips. At $10 per pip per standard lot, that is $3-7 per lot in hidden costs — comparable to or exceeding the commission on a Raw account. Over 20 lots per month, the difference between the best and worst execution quality translates to roughly $40-120 per month in slippage costs alone. Combined with spread costs, execution quality can account for 30-40% of total trading costs.

Do these results apply to larger order sizes?

Our test used 0.01 lot orders to isolate execution infrastructure performance. Larger orders (1+ lots) will experience higher latency and more slippage because they consume more liquidity depth. However, the relative ranking between brokers generally holds: a broker with fast execution on micro lots typically also has fast execution on standard lots, because the underlying infrastructure (data centre proximity, LP relationships, aggregation engine) is the same.

Executive Summary

Key Findings at a Glance

Exness has the fastest median execution at 31ms with a 99.8% fill rate.
Average median latency across all 25 brokers is 59ms. 4 brokers deliver sub-40ms median execution.
cTrader is the fastest platform: 46ms average median vs 60ms (MT5) and 66ms (MT4).
Average negative slippage rate is 25.1% of orders. The best broker limits negative slippage to under 17% of fills.
Average fill rate across all brokers is 99.4%. Every broker in our test achieved at least a 98% fill rate.

Why Execution Speed Matters

Spreads are visible. Commissions are disclosed. But execution quality — the speed at which your order fills, the price you actually receive versus the price you requested — is the hidden variable that most traders never measure.

Our Spread Study 2026 measured what brokers charge. This study measures what they deliver. A broker can advertise 0.0 pip spreads, but if execution latency introduces 0.5 pips of negative slippage on 25% of orders, the effective cost is far higher than the headline number.

For a trader executing 20 standard lots per month, the difference between the best and worst execution quality in our test translates to approximately $40-120 per month in slippage costs alone — a figure comparable to or exceeding the total commission bill on a Raw account.

Methodology

We submitted 500 market orders per broker (12,500 total) across 25 EU-regulated brokers over 10 consecutive trading days (27 May - 7 June 2026). Every order was a 0.01 lot EUR/USD market order placed through each broker's API or platform interface.

What We Measured

Click-to-fill latency: The time (in milliseconds) between order submission and fill confirmation. Measured via API timestamps cross-referenced with client-side timestamps.
Slippage distribution: Whether the fill price was better than requested (positive), equal (zero), or worse (negative). Expressed as a percentage of all fills.
Fill rate: The percentage of orders that received a fill (vs rejected or timed out).
Requote rate: The percentage of orders that received a requote before filling.

Sessions Covered

London Session

08:00 - 16:00 GMT

Peak EUR/USD liquidity. 250 orders per broker.

New York Session

13:00 - 21:00 GMT

High volume with overlap. 250 orders per broker.

Controls & Limitations

All orders were placed from the same VPS (Equinix LD4, London) to eliminate client-side network variability.
Only EUR/USD was tested. Results may differ for less liquid pairs.
Order size was 0.01 lots. Larger orders will experience higher latency and more slippage due to liquidity depth consumption.
The Asian session was excluded because EUR/USD liquidity is significantly reduced, introducing noise that obscures infrastructure-level performance differences.
Orders placed during scheduled high-impact news events (NFP, ECB, FOMC) were excluded from median calculations but included in P95.

Key Insight: Platform Matters Less Than Broker

The difference between platforms at the same broker is typically 5-15ms. The difference between the fastest and slowest broker on the same platform exceeds 50ms. Choose your broker first for execution quality, then pick the fastest platform they offer.

Execution Speed by Trading Session

London session execution is consistently faster than New York, reflecting higher EUR/USD liquidity depth during European trading hours. The gap widens at the P95 level, where New York sessions show more variance in fill times.

Key Findings

The 40ms Threshold

4 of 25 brokers deliver sub-40ms median execution on EUR/USD. These brokers all share common infrastructure traits: Equinix data centres (LD4 London, NY4/NY5 New York, TY3 Tokyo), direct connections to Tier-1 liquidity providers, and STP/ECN execution models. For scalpers and algorithmic traders, this 40ms threshold is the minimum standard. Above it, slippage frequency increases measurably.

Slippage Is Not Random

Brokers with the fastest execution also have the most favourable slippage distributions. The top 5 brokers by execution speed show positive slippage on over 10% of orders, compared to under 5% for the slowest 5 brokers. This is not coincidental: faster execution means the price is less likely to move against the trader between order submission and fill.

cTrader's Consistent Speed Advantage

Across every broker that supports it, cTrader delivered the lowest median latency. The average advantage over MT5 is 14ms and over MT4 is 20ms. cTrader's FIX-based protocol and modern architecture reduce the overhead of the legacy MetaTrader bridge layer. For traders whose strategy depends on execution speed, cTrader is the clear choice where available.

Requotes Are Concentrated

20 brokers in our test showed requote rates above 2%. All of them use a market-maker or hybrid execution model. Pure STP/ECN brokers show requote rates of 0-0.5% because orders are filled at the best available market price without dealer intervention. If you encounter frequent requotes, it is a strong signal that orders are passing through a dealing desk.

The Real Cost of Slow Execution

Combining negative slippage frequency and magnitude, the worst-execution broker in our test adds an implicit cost of approximately $2.48 per standard lot in slippage alone. Over 20 lots per month, that is $595 per year in hidden costs. Combined with the cost differences from our spread study, execution quality can account for 30-40% of total trading costs.

Practical Implications by Trader Type

Scalpers & Day Traders

Target sub-40ms median latency brokers (top 4 in our test)
Use cTrader where available for the fastest fills
Trade during London session for best execution conditions
Prioritise brokers with <20% negative slippage rate
Avoid any broker with requote rate >1%

Swing & Position Traders

Execution speed is secondary to spread cost and swap rates
Any broker with >99% fill rate is adequate
Focus on slippage distribution over raw latency
Platform choice matters less — pick for features
Session timing is irrelevant for multi-day holds
