Latency, execution speed, and slippage can significantly impact your trading results. Learn how orders are executed, why slippage occurs, and how to evaluate your trading platform's execution quality for more informed trading decisions.
Most traders obsess over entries, exits, indicators, and risk-reward ratios, and neglect the one thing that determines whether any of it actually happens the way they planned: execution. When you click buy, a hidden chain of events unfolds in milliseconds, and the price you end up with can differ from the price you saw. Brokers advertise impressive-sounding execution speeds, "35 milliseconds," "no requotes," "no slippage", but those headline numbers rarely tell the full story, and understanding what they leave out is one of the most valuable things a serious trader can learn.
This guide explains what latency, execution speed, and slippage actually are, how they interact, and, crucially, what your platform's marketing typically isn't telling you about them. The honest framing throughout is this: some of what affects your fills is structural and unavoidable, some is down to a platform's genuine quality, and most of it is measurable, yet almost no retail trader ever measures it. By the end, you'll understand the mechanics and know how to judge your own platform's execution rather than trusting the headline figure. This article is educational and does not constitute investment advice.
For traders who want the core picture immediately, here's how it works.
When you place an order, it travels from your device, across your internet connection, through your platform, to the broker's server, out to a liquidity provider, and back with a confirmation. Latency is the time that whole round trip takes. Execution speed is how fast the order is filled. Slippage is the difference between the price you expected and the price you actually got.
Here's the key thing the marketing obscures: the "35 milliseconds" a broker advertises usually describes only the broker-server portion of that chain, not the full journey from your device. Your real experience includes your own internet, your distance from the server, and market conditions, all of which the headline number ignores.
And here's the empowering part: execution quality is measurable. Most traders never measure it, so they have feelings where they should have data. The rest of this guide explains the mechanics and how to actually check your own platform.
Latency is the foundation of this whole topic, so it's worth understanding precisely rather than vaguely.
Latency is the time your order spends travelling from your platform to the liquidity where it's filled, and back again with a confirmation. It's measured in milliseconds, and it matters for a simple reason: the longer that round trip takes, the more time the market has to move before your order is filled, which means more room for the price to shift away from what you saw. More latency means more opportunity for slippage. Latency itself isn't misconduct, it's a structural feature of how orders travel, but higher latency structurally produces worse fills.
Several things stacked together, and this is where the headline execution figure becomes misleading. Your order's total journey includes your own device and platform, your internet connection, the physical distance to the broker's server, the broker's server processing, and the liquidity provider's response. The broker's advertised execution speed typically measures only their internal server processing, one link in a longer chain. Your home internet connection alone can add a substantial delay, and physical distance matters too, a trader far from the broker's server experiences more latency than one located near it.
This is why the full picture is so different from the advertised one. A broker might genuinely process orders on their server in tens of milliseconds, but by the time you add your internet connection, your distance, and everything else, the real round trip you experience can be considerably longer. The headline number isn't necessarily dishonest, but it describes only the part of the chain the broker controls, not the delay you actually live with. Understanding this gap between "broker-side speed" and "real-world latency" is the first thing your platform isn't telling you.
Slippage is the concept traders complain about most and understand least, so it deserves careful, honest treatment, including the uncomfortable parts.
Slippage is the difference between the price you expected when you placed an order and the price at which it was actually filled. If you click buy on a pair at one price and, by the time your order executes, the market has moved slightly, you may be filled at a different price. That difference is slippage. It can be negative, filling you at a worse price than expected, or in some cases positive, filling you at a better one.
This is the crucial, honest distinction, and the answer is mostly the latter. A significant portion of slippage is structural rather than misconduct. Prices genuinely move in the milliseconds your order is travelling, especially during fast markets, and no execution system can eliminate that, because the structure of markets simply doesn't allow zero slippage. When you fire a market order and the price shifts before it fills, that slippage is largely a consequence of latency and real market movement, not a broker cheating you.
That said, it's not entirely innocent either. A platform with consistently poor infrastructure, slow processing, weak liquidity access, high latency, is genuinely filling you worse than a well-built one would, even if no single fill is "manipulation." So the honest position is nuanced: slippage is a normal, structural cost of trading that no platform can remove, but the amount of slippage you suffer is meaningfully affected by the quality of the platform's infrastructure and liquidity. Both things are true at once, and any explanation claiming either "all slippage is the broker cheating" or "slippage is never the broker's concern" is oversimplifying.
Predictably, during volatility and around news. Slippage during major news events happens because prices move extremely quickly, spreads widen, and the liquidity available at your expected price can disappear. If you place a market order into a high-impact economic release, significant slippage isn't a malfunction, it's almost guaranteed by the conditions and the order type you chose. This is important because traders often fire market orders into news and then blame the platform for the slippage that the order type made inevitable. Understanding this lets you manage it, by using appropriate order types and being cautious around known volatility, rather than simply resenting it.
Execution speed is how quickly your order is actually filled once it reaches the market, and it's the metric brokers advertise most prominently, which is exactly why it deserves scrutiny.
Fast execution matters because it reduces the window in which price can move against you, which reduces slippage and the chance of requotes. In that sense, faster is genuinely better, and execution speed is a real quality factor, not just marketing. The problem isn't that speed is unimportant, it's that the advertised numbers are easy to misread.
Because, as with latency, the advertised figure typically measures only the broker's server-side processing, not your full real-world experience. A broker stating an average execution speed of a few tens of milliseconds is describing the time once your order hits their servers, which excludes your device, your internet connection, your distance from the server, and the liquidity provider's response. Your actual, end-to-end experience is the sum of the whole chain, and it's slower than the headline.
There's another subtlety worth knowing. Execution speed figures are sometimes derived in conditions that don't reflect live trading. On a demo account, for instance, orders don't need to be filled by an actual liquidity provider because no real money is involved, so trades never truly leave the platform. This means demo execution can appear faster and show no slippage or partial fills, none of which reflects what happens with real orders in live conditions. So a fast number isn't automatically a fast real-world experience, and understanding where and how a speed figure was measured matters as much as the figure itself.
Bringing it together, here are the specific things the typical execution marketing leaves out, the gaps that this whole article exists to illuminate.
These claims sound great but deserve scrutiny, because they can hide trade-offs. A requote is when a platform, rather than filling your order at the price you clicked, comes back and asks whether you accept a new price, which typically happens when the market has moved. "No requotes" can be a genuine feature of platforms that route orders straight through to liquidity, where instead of a requote you simply get a fill, sometimes with slippage if the price moved. So "no requotes" doesn't necessarily mean better execution overall, it can just mean the effect shows up as slippage instead.
Similarly, guarantees of "no slippage" should prompt a question rather than relief, because the structure of markets doesn't allow genuinely zero slippage in all conditions. A platform promising it may be compensating in ways that aren't advertised, such as wider spreads or the ability to reject orders that would have been profitable for you. The useful question is never "does this platform advertise no slippage?" but "what is actually happening to my fills, in both directions, and at what total cost?" Marketing claims are a weaker signal than most traders assume, and the more meaningful measure sits behind them.
This is a genuinely useful concept most traders never encounter. Because some slippage is structural and inevitable, the fair question isn't whether slippage exists but whether it happens symmetrically, that is, whether you sometimes get positive slippage (a better price) as well as negative slippage (a worse one). Fair execution tends to produce slippage that works in both directions, because genuine price movement is random and should occasionally favour you. Slippage that only ever seems to go against you is a more meaningful warning sign than slippage existing at all. This is exactly the kind of thing the headline numbers never tell you, and exactly the kind of thing you can measure yourself.
Here's the empowering part, and the practical heart of the article: execution quality is measurable, and the fact that most traders never measure it is precisely why they're at the mercy of marketing claims.
The single most valuable habit is logging your requested price versus your filled price on your trades. Most traders never record this, which means when they have a bad experience they have only feelings, when they could have a sample of real data. By recording what price you clicked and what price you actually got, over a meaningful number of trades, you build an actual picture of your execution rather than an impression.
From that data, several things become visible. You can see your typical slippage and, importantly, whether it's symmetric or consistently against you. You can see how your fills behave in calm conditions versus during volatility and news, which separates structural slippage from a genuine platform problem. You can note requote frequency if your platform uses them, and how your execution changes at busy times versus quiet ones. Over several weeks, this turns vague suspicion into evidence, and evidence is what lets you judge a platform fairly rather than either trusting the marketing or blaming the broker for every unfavourable fill.
Some of the factors are within your control, which is worth knowing. Your internet connection quality and stability directly affect the latency you experience, so a reliable connection helps. Your physical distance from the broker's server matters, which is why some serious algorithmic traders and scalpers use hosting solutions located near the broker's servers to minimise latency, though this is an advanced consideration relevant mainly to speed-sensitive strategies rather than most traders. And your choice of order type matters enormously, since firing market orders into volatile conditions invites slippage, while more controlled order types can protect your price at the cost of guaranteed execution.
The broader point is that execution quality is a shared responsibility between the platform's infrastructure and your own setup and choices. A transparent, well-built platform gives you good infrastructure and honest conditions, and Skyriss is built around that kind of execution transparency, but you contribute the connection, the location, the order-type discipline, and, above all, the willingness to actually measure what's happening rather than guess. Whatever platform you use, forex and CFD trading carry a high risk of losing money rapidly due to leverage, and execution quality is one part of managing that risk rather than a way around it.
Latency is the time your order takes to travel from your platform to where it's filled and back with a confirmation, measured in milliseconds. Higher latency gives the market more time to move before your order fills, which increases the chance of slippage.
Slippage is the difference between the price you expected and the price your order actually filled at. It happens because prices move in the milliseconds your order is travelling, especially during fast markets and news, when spreads widen and liquidity at your expected price can disappear.
Mostly it's structural rather than misconduct, since prices genuinely move while your order travels and no system can eliminate that. However, a platform with poor infrastructure or weak liquidity genuinely fills you worse than a well-built one, so the amount of slippage you suffer is affected by platform quality even though slippage itself is normal.
Because the advertised figure usually measures only the broker's internal server processing, not your full experience. Your real latency also includes your device, internet connection, distance from the server, and the liquidity provider's response, so your actual end-to-end speed is slower than the headline number.
Not necessarily. "No requotes" can mean the effect shows up as slippage instead, and "no slippage" guarantees can be offset by wider spreads or the ability to reject unfavourable orders. These claims are weaker signals than they appear, and the more useful question is what's actually happening to your fills in both directions.
It's whether your slippage sometimes favours you (positive slippage) as well as going against you (negative slippage). Because genuine price movement is somewhat random, fair execution tends to produce slippage in both directions. Slippage that only ever goes against you is a more meaningful warning sign than slippage simply existing.
Log your requested price versus your filled price across many trades. This builds real data on your typical slippage, whether it's symmetric, how it behaves in calm versus volatile conditions, and how often requotes occur. Most traders never do this, which is why they rely on impressions instead of evidence.
Because prices move very quickly during high-impact releases, spreads widen, and the liquidity available at your expected price can vanish. Market orders placed into news are almost guaranteed to experience slippage due to these conditions and the order type, rather than because of any platform malfunction.
Latency, execution speed, and slippage are the invisible machinery behind every trade you place, and the marketing around them is designed to reassure rather than to inform. The advertised "35 milliseconds" describes only the part of the journey the broker controls, not the full chain from your device that determines your real experience. The "no slippage" and "no requotes" promises can conceal trade-offs rather than deliver genuinely superior execution. And slippage itself, the thing traders complain about most, is largely a structural feature of how markets work, even as its magnitude genuinely reflects a platform's quality.
The through-line is that execution is more honest than the marketing about it. Some of what affects your fills is unavoidable physics and market structure, some is real platform quality, and the two get blurred together by headline numbers that flatter and claims that oversimplify. Cutting through it doesn't require distrust so much as measurement, because the single most powerful thing you can do is stop relying on feelings and start logging what price you asked for against what price you got.
That's the real message. Execution quality is knowable, and the traders who measure it understand their platform in a way the marketing will never give them. Choose a platform built on transparent, reliable execution, Skyriss aims to be exactly that, contribute your own good setup and order-type discipline, and measure your fills rather than trusting a number on a page. What your platform isn't telling you, you can find out for yourself, and doing so is part of trading with your eyes genuinely open.
