Scalping and Broker Cost: Why the Table Matters
Scalping and broker cost are joined at the hip: when you're placing dozens of trades a day, the fee table on your broker's website will decide your outcome faster than any entry signal, indicator, or "perfect setup" ever could. Most scalpers spend weeks refining a strategy and about ten minutes checking what it actually costs to run.
That's backwards. Here's why the numbers deserve at least as much attention as the chart.
Why Scalping and Broker Cost Are Inseparable
A scalping strategy might net 1–3 pips per trade. If your all-in cost — spread plus commission — is even 0.5 pips higher than a competing broker's, you've lost a meaningful slice of your edge before the market has moved a tick in your favour.
Run the maths on frequency:
- 20 trades a day × 5 trading days = 100 round-turns a week
- An extra 0.3 pips of cost per round-turn = 30 pips a week given away
- Over a month, that's often more than the strategy's entire net profit
This is why professional scalpers obsess over cost structure the same way they obsess over win rate. A brilliant setup running on an expensive account can still lose money. A mediocre setup on a genuinely cheap account can survive. The table isn't a footnote — it's part of the strategy.
The Real Cost Stack (Not Just the Spread)
Headline spreads are marketing. Your real cost is a stack of four things:
1. Spread — the gap between bid and ask, which widens and narrows through the day 2. Commission — charged per lot on raw/ECN-style accounts, on top of a tighter spread 3. Swap — overnight financing, largely irrelevant if you close every scalp same-day, but worth checking on /rates.html in case a trade runs long 4. Slippage — the silent one; the difference between the price you clicked and the price you got, especially around news or thin liquidity
Two brokers can quote the same "average spread" and still cost you differently once commission and slippage are added. Never compare on spread alone — compare the stack.
Spread vs Commission Accounts: What Actually Suits Scalping
Most brokers offer a choice, and it matters more for scalpers than for swing traders:
| Account type | Typical structure | Best suited to | |---|---|---| | Standard/spread-only | Wider spread, no commission | Lower frequency, simpler statements | | Raw/ECN + commission | Tighter spread, fixed commission per lot | High-frequency scalping, if raw spread is genuinely tight |
Pepperstone's Razor account and IG's MetaTrader offering are both built around this raw-plus-commission model, while their standard platform pricing wraps cost into the spread instead. Neither structure is automatically better — it depends on your volume and average trade size. Model both against your own trade count using /audit.html before choosing.
Session Timing Changes Your Cost, Not Just Your Opportunity
Spreads aren't static. They breathe with liquidity:
- London/New York overlap — typically the tightest spreads on major pairs
- Asian session — often wider on GBP and EUR pairs due to lower volume
- Around major news releases — spreads can spike sharply for seconds to minutes
- Rollover (5pm New York) — brief widening on most brokers as liquidity providers reprice
A scalper trading GBP/USD at 3am UK time is very likely paying a different effective cost than the same trader at 9am, even on the same account. If your strategy scalps outside peak hours, factor that widening into your expectancy — don't just use the daytime average you saw advertised.
Building a Personal Cost Audit Before You Scale Up
Before increasing size or frequency on any scalping strategy, run a simple audit:
1. Log your actual trades for two weeks — pair, time, spread paid, commission, and fill price vs intended price 2. Total the cost stack per trade, not just the spread you assumed going in 3. Compare against a second broker using the same trade log, via /audit.html 4. Check execution quality, not just price — requotes and delays cost money even at a "cheap" spread 5. Revisit quarterly — broker pricing and your own trading hours can both drift
This turns "I think my broker is cheap" into "I know my actual cost per 100 trades," which is the only number that matters for a scalping strategy's survival.
Choosing a Broker for Scalping Without Guesswork
Some brokers restrict or discourage scalping outright, especially on dealing-desk accounts — always check the terms before building a strategy around one. FCA-regulated brokers like Pepperstone and IG generally support scalping across their raw-spread and platform accounts, but their pricing, execution model, and permitted strategies differ enough that you shouldn't assume equivalence.
Practical steps:
- Confirm scalping is explicitly permitted in the account terms
- Compare live spread and commission figures on /brokers/index.html — not last year's marketing numbers
- Check minimum deposit and platform fit against your existing MetaTrader or cTrader setup
- Test on a small live position before scaling, since demo fills often don't reflect real slippage
Conclusion: Let the Table Decide Before the Setup Does
Scalping and broker cost aren't two separate topics — for a high-frequency strategy, cost *is* the strategy's second biggest variable after the market itself. Spend real time on the fee table, not just the chart: total the spread, commission, swap and slippage, check it at the hours you actually trade, and re-audit it regularly. Get that right first, and your setup finally gets a fair chance to prove itself.
Key takeaways
- Scalping and broker cost are inseparable — with 20+ trades a day, spreads and commissions compound faster than any edge from your entry technique
- A 0.3 pip difference in average spread can erase a scalper's entire monthly profit once multiplied across hundreds of round-turns
- Always compare the full cost stack: spread + commission + swap + slippage, not just the headline spread number
- Use /audit.html and /brokers/index.html for live, current broker figures — never rely on memorised or advertised 'from' spreads
- Test execution quality (fills, requotes, latency) on a demo or small live account before committing to a scalping strategy on any broker
- Session timing and pair choice affect your real cost more than most people realise — spreads widen outside peak liquidity
Frequently asked questions
- What counts as a 'good' spread for scalping?
- There's no fixed number that works for everyone — it depends on your pair, timeframe and trade frequency. Rather than memorising a target spread, run your actual trade plan through /audit.html so the cost is calculated against your real volume and holding time.
- Is commission-based pricing always cheaper than spread-only for scalpers?
- Not always. Raw-spread-plus-commission accounts (common at Pepperstone and similar ECN-style brokers) can be cheaper for high-frequency scalping, but only if the raw spread is genuinely tight. Check the combined cost, not just the commission line, using the cost tool.
- Does IG or Pepperstone suit scalping better?
- Both are FCA-regulated and support scalping, but they price differently — IG's own platform pricing versus its MetaTrader offering, and Pepperstone's Standard vs Razor accounts, all carry different cost structures. Compare current figures on /brokers/index.html rather than assuming one is universally cheaper.
- How much does slippage really cost a scalper?
- On fast-moving pairs during news or thin liquidity, slippage can add the equivalent of several pips per week for an active scalper. It's rarely disclosed upfront, so track your own fill quality alongside the quoted spread.
- Should I switch brokers just to save on spread?
- Only after checking the full picture — spread, commission, swap, minimum deposit, and execution reliability. A slightly wider spread with faster, more consistent fills can beat a cheaper headline price. Use /audit.html to model the switch before moving funds.
- Do swap charges matter for scalpers who close trades same day?
- Usually not, since swaps apply to positions held overnight. But if you occasionally hold a scalp longer than planned, check /rates.html so an unexpected swap doesn't quietly eat into a trade that was otherwise profitable.
