What Does STP Execution Mean for My Spreads as a Beginner?
If you have spent more than five minutes researching online brokers, you have likely run into the acronym "STP." It stands for Straight-Through Processing. It sounds technical, but in the world of retail trading, it is a big deal because it defines how your broker handles your orders and, more importantly, how much you actually pay to trade.
With the forex market volume stated at over $7.5 trillion traded daily, brokers have a massive incentive to move your order quickly. But how they do it changes your experience entirely.
What is STP Execution?
In an STP model, your broker acts as a bridge. When you click "buy" or "sell," the broker passes your order directly to their liquidity providers (large banks, hedge funds, or other financial institutions). There is no "dealing desk" in the middle deciding whether or not to take the other side of your trade.
If best forex broker for beginners uk your broker is a true STP broker, they aren't betting against you. They make their money either through a small commission or by adding a slight "markup" to the spread they receive from their liquidity providers.
The Spread Markup Explanation
This is where beginners get tripped up. You will see brokers advertising "tight spreads," but that phrase is meaningless without context. When a broker sources prices from liquidity providers, the raw spread (the difference between the Buy and Sell price) is usually near zero. To make a profit, the broker adds a markup.
If you see a spread of 1.5 pips, it usually consists of:

- Raw Liquidity Provider Spread: 0.2 pips
- Broker Markup: 1.3 pips
Always sanity-check these numbers. If a broker claims "0.0 spreads" but doesn't explicitly state that this is only available on specific "Raw" account types—or fails to mention a commission per lot—they are playing games with your expectations.
The Trust Signals: FCA and FSCS
Before you even look at spreads, look at the badge. If you are a UK trader, you must ensure the broker is regulated by the Financial Conduct Authority (FCA). This isn't just a suggestion; it’s your safety net.
FCA regulation forces brokers to hold client funds in segregated accounts. This means if the broker goes bust, your money isn't lumped in with their operating capital. Furthermore, the Financial Services Compensation Scheme (FSCS) offers protection of up to £85,000 per eligible claimant if the firm fails. Never deposit money with a firm that doesn't display its FCA registration number clearly in its footer.
Negative Balance Protection and Leverage
Since 2018, the FCA has capped leverage for retail traders at 30:1 for major currency pairs. While some beginners think this is "limiting," it is actually a vital safety measure. Combined with mandatory Negative Balance Protection (NBP), it means you cannot lose more than the money you have in your account. You will never owe the broker money because of a sudden market crash.
Comparing Brokers: The Reality Check
When you start evaluating brokers, don't just look at their landing pages. You need Click here for more to dig into the account types. Let's look at how firms like TIOmarkets (Tio Markets UK Limited), Pepperstone, and XTB structure their offerings.
Broker Account Type Focus Transparency Note TIOmarkets STP/ECN focus Offers various tiers; check if markup is fixed or floating. Pepperstone Standard vs. Razor Clear distinction between commission-based and spread-only models. XTB Standard/Pro Often uses a hybrid model; check execution speed on mobile.
When you compare account types, you will usually find two main paths:
- Standard Account: Zero commission, but higher spread (the markup is built-in). Better for beginners who want simple math.
- Raw/ECN Account: Low or zero spreads, but you pay a fixed commission per lot. Better for active traders who want to see the "true" market price.
How to Test Execution Before You Fund
Stop looking for "the best" broker and start looking for the one that fits your style. The only way to know if a broker’s STP execution is actually "fast" is to test it yourself.
1. Use a Demo Account
Opening a demo account before funding live is non-negotiable. Don't just trade on the demo; stress-test it. Try to place orders during high-volatility events (like a US Non-Farm Payroll report). Does the platform freeze? Does the spread widen to an insane level? If the demo environment is sluggish, the live environment will likely be worse.
2. Test Mobile Usability
Many broker reviews ignore the mobile app experience. If you plan on checking your trades on the go, download the app. Is the order entry clean? Can you see the spread clearly before you hit the "Buy" button? If the UI is cluttered or hidden, skip it. A platform that hides its fees in sub-menus is a red flag.
Why "0.0 Spreads" Can Be Misleading
I get annoyed when I see marketing materials screaming "0.0 Spreads!" without mentioning the fine print. Usually, this refers to the *interbank* spread, not the price you actually get. On a retail STP account, your spread will fluctuate based on liquidity. If the market is quiet, that 0.0 might become 0.8. If the market is volatile, it might jump to 2.0.
Always verify the "average spread" list provided by the broker. If they don't provide one, or if they only show the "lowest possible spread" rather than the average, be cautious. Professional traders look for consistency, not the occasional "best" price.

Final Checklist for Beginners
Before you hit the "Deposit" button, perform this final audit:
- Regulatory Check: Confirm they are FCA-authorised and check the register.
- Fee Schedule: Look for hidden inactivity fees. Some brokers start charging you if you don't trade for 90 days.
- Minimum Deposits: Sanity-check the minimum funding requirements. If a broker requires a £5,000 minimum for an STP account, it might not be the right fit for a beginner starting with £500.
- Execution Style: Are they actually sending orders to liquidity providers, or are they a market maker? If they won't disclose their execution model, walk away.
Trading is risky enough without worrying about whether your broker is "padding" your spreads to death. By choosing an FCA-regulated firm that is transparent about its STP execution and by testing their demo platform, you are already ahead of 90% of retail traders. Take your time, verify the costs, and prioritize your capital protection over "tight spread" hype.
Risk Warning: Trading leveraged products like forex and CFDs carries a high level of risk to your capital. You should only trade with money you can afford to lose. If you are unsure, seek independent financial advice.
