Scalping and Broker Cost: Why the Table Matters More
Scalping and broker cost are so tightly linked that the setup you trade almost doesn't matter until you've done the cost maths first. Scalpers aim for small, frequent gains — often 5 to 15 pips per trade — which means the spread, commission and slippage you pay on every single entry and exit take a proportionally huge bite out of your edge. Get the cost table wrong and even a genuinely good setup will bleed you dry through sheer trade frequency.
Why Scalping and Broker Cost Are More Important Than the Entry Signal
A swing trader targeting 100+ pips can absorb a 1.2 pip spread without much drama — it's noise. A scalper targeting 8 pips cannot. That same 1.2 pip cost is now 15% of the entire target, before slippage or commission are added.
This is the core reason cost structure deserves more attention than pattern recognition for high-frequency strategies:
- Frequency multiplies cost. Twenty trades a day at 1 pip of total cost each is 20 pips of drag — more than most scalp targets combined.
- Small edges get erased fast. A 55% win rate with a 1:1 risk-reward ratio can flip negative once realistic costs are subtracted.
- Marketing spreads aren't real spreads. Advertised "from 0.0 pips" figures are best-case, low-liquidity-hour numbers, not your Tuesday-lunchtime reality.
Before refining entries further, run your intended pair and session through /cost-impact.html to see how sensitive your strategy actually is to cost changes. If a 0.2 pip shift turns your backtest from profitable to break-even, you don't have a robust strategy — you have a cost-dependent one.
The Three Costs That Actually Hit a Scalper
Not every cost line applies equally to short-term trading. Focus your table on the three that do:
1. Spread — the immediate, guaranteed cost on every trade, paid whether you win or lose. 2. Commission — charged per lot on raw/ECN-style accounts, usually cheaper at volume but adds a fixed cost regardless of trade outcome. 3. Slippage — the gap between the price you clicked and the price you got, driven by execution speed and liquidity.
Swap/overnight financing rarely matters here since scalpers close within minutes. Don't let a broker's headline low-swap offer distract you from the spread and execution quality that actually decide your outcome.
Building Your Own Cost Table
Rather than trusting a comparison chart you didn't build yourself, construct a simple table for each broker and account type you're considering:
| Account type | Typical spread (pips) | Commission per lot | Est. slippage | Total cost per round trip | |---|---|---|---|---| | Standard | ? | £0 | ? | ? | | Raw + commission | ? | ? | ? | ? |
Fill this using live, current figures from /audit.html, not old forum posts or a broker's homepage banner. Spreads move with liquidity and volatility, so pull numbers during the session you actually plan to trade — London open costs differ from a quiet Asian session.
Once you have real totals, compare them against your average target size. If total cost exceeds roughly 20-25% of your typical target, the strategy needs either a wider target, fewer trades, or a cheaper execution model.
Spread vs Commission Accounts: Which Wins for Scalping?
This depends entirely on your trade volume, and there's no universal answer — which is exactly why fabricated "best account" claims are unhelpful.
Commission-based (raw spread) accounts tend to suit scalpers who: - Trade high volume daily - Qualify for volume-based commission discounts - Need consistently tight spreads during volatile news
Standard variable-spread accounts can suit scalpers who: - Trade fewer, more selective setups per day - Want a single all-in cost with no separate commission line - Trade pairs where the standard spread is already competitive
Both Pepperstone and IG offer multiple account structures, including raw/ECN-style options alongside standard accounts, and both publish their execution details on their platform pages. Rather than guessing which suits your volume, check current spread and commission figures for your specific pairs on /brokers/index.html, then plug them into your cost table.
Execution Quality Matters as Much as the Quoted Number
A tight quoted spread means nothing if your orders slip badly during execution. Two brokers can advertise identical spreads and deliver very different real-world results depending on:
- Server location and latency relative to your own connection
- Order execution model (market vs instant execution)
- Liquidity provider depth during your trading session
- Requote policy during fast-moving news
Test this yourself: place a batch of small trades during your normal session and log the requested price versus the filled price. A pattern of consistent negative slippage is a real cost that no spread table captures. PipTax's /methodology.html page explains how we account for execution factors alongside quoted spreads when comparing brokers, which is worth reading before you assume the cheapest headline number is the cheapest real outcome.
Adjusting Your Strategy Once You Know the Real Cost
Once your cost table is built and honest, you have three levers to pull if the maths doesn't work:
- Widen your target. Even a small increase from 8 to 12 pips can shift the cost-to-target ratio significantly.
- Reduce trade frequency. Fewer, higher-conviction entries lower total cost drag even if the win rate stays the same.
- Switch account type or broker. Sometimes the strategy is fine — the account structure is wrong for your volume.
Whatever you choose, revisit the numbers periodically. Spreads and commission structures do change, and a broker that was cheapest for your style last year may not be this year.
Conclusion: Treat the Cost Table as Part of the Strategy
Scalping and broker cost cannot be separated — the cost table isn't a footnote to your strategy, it's a core input that decides whether the setup is even worth trading. Build a realistic, session-specific cost table before you refine entries any further, check it against current numbers using PipTax's cost tool, and revisit your broker comparison regularly as conditions change. Trading remains risky regardless of cost structure, but at least you'll know the maths is working with you, not against you.
Key takeaways
- Scalping and broker cost are inseparable — at 5-15 pip targets, spread and commission can eat 20-50% of gross profit before you even factor in slippage.
- A 0.2 pip spread difference across 20 trades a day is not trivial; run the numbers through a cost calculator before choosing a setup.
- Commission-based raw-spread accounts usually beat standard variable-spread accounts for high-frequency scalping, but only if volume discounts apply — check the fine print.
- Execution speed and requotes matter as much as the quoted spread; a cheap spread with poor fills can cost more than a slightly wider one with fast execution.
- Swap and overnight financing are irrelevant to true scalpers who close within minutes, but slippage and commission structure are not — build your cost table around what actually applies to your holding time.
- Use PipTax's cost tool and broker pages to compare real, current numbers rather than relying on marketing claims or forum anecdotes.
Frequently asked questions
- What is the biggest cost mistake scalpers make?
- Focusing entirely on the entry signal and ignoring how spread, commission and slippage stack up against a small target. A strategy that wins 60% of trades can still lose money if the average cost per trade is close to the average target size.
- Is a commission account always cheaper for scalping?
- Not always. Raw-spread-plus-commission accounts are often cheaper at high volume, but low-volume traders sometimes do better on a standard variable-spread account with no commission. Run both through a cost calculator using your real trade count and size.
- Do swaps matter for scalping?
- Rarely. If you close every position within minutes and never hold overnight, swap and financing charges won't apply. Focus your cost table on spread, commission and slippage instead.
- How much does slippage really cost a scalper?
- It varies by broker, pair and time of day, but even 0.1-0.3 pips of average slippage per trade adds up fast across dozens of daily trades. Track your actual fills against quoted prices for a week to see your real number.
- Can I scalp profitably on any broker?
- Technically yes, but the maths gets harder as costs rise relative to your target. Some brokers also restrict or discourage scalping in their terms, so check execution model and policy on the broker's page before committing capital.
