Scalping and Broker Cost: Why the Table Matters
Scalping and broker cost go hand in hand: no matter how sharp your entries are, if the spread, commission and slippage eat your edge, the strategy will lose money over time. This article walks through why the cost table deserves more attention than the setup itself, and how to check it properly before you risk a single trade.
Why Scalping and Broker Cost Are Inseparable
Scalping is a numbers game built on high trade frequency and small per-trade targets. That combination makes it uniquely sensitive to cost:
- A swing trader might take 10-20 trades a month; a scalper can take that many in a single session.
- Small targets (a few pips) mean cost as a percentage of the target is much higher than for a trade aiming for 50+ pips.
- Costs are paid on every single trade, win or lose — they're not optional and they don't average out in your favour.
Put simply: your setup decides whether you're right or wrong on direction. Your broker's cost structure decides how much of being "right" you actually keep. A profitable-looking backtest can turn negative in live trading purely because the cost assumptions were wrong or outdated.
This is why professional scalpers spend as much time studying account types and execution as they do refining entry rules. The setup gets you in the game; the cost table decides whether you can win it.
What Actually Makes Up Your Trading Cost
"Spread" is only part of the picture. To understand your true cost per trade, add up:
- Spread — the gap between bid and ask, charged on every trade
- Commission — a fixed or per-lot fee, common on raw/ECN-style accounts
- Slippage — the difference between requested and filled price, especially in fast markets
- Swap/rollover — usually not relevant for scalpers who close same-day, but check if you ever hold overnight
- Platform or data fees — rare, but some setups charge for premium feeds or VPS hosting needed for speed
Two accounts advertising the same headline spread can have very different total costs once commission and typical slippage are included. Always calculate a total cost per round turn, not just the quoted spread, before judging whether an account suits scalping.
A Simple Way to Compare Accounts
Don't rely on marketing pages. Build a basic comparison using your own trade size and frequency:
1. Note your typical lot size and average trades per day 2. Pull the spread and commission for each account type you're considering 3. Add a realistic slippage estimate based on the pairs and sessions you trade 4. Multiply by your expected monthly trade count 5. Compare the monthly cost totals side by side
| Account type | Spread | Commission | Typical use case | |---|---|---|---| | Standard/variable spread | Wider | Usually none | Lower frequency, simpler cost tracking | | Raw/ECN spread | Tighter | Per-lot fee | High-frequency scalping, needs total-cost math |
Rather than guessing at numbers, run your real trade size and frequency through PipTax's [cost tool](/audit.html) to see the actual monthly difference between account types — it does this maths for you using live inputs rather than estimates.
Execution Speed and Requotes Matter Too
Cost isn't only about the price you're quoted — it's about the price you actually get filled at. For scalpers, a few things to check before committing to a broker:
- Execution model: market maker vs ECN/STP can affect how orders are handled during volatile moves
- Requote policy: does the broker requote during news, or fill at the next available price?
- Average execution speed: some brokers publish this, others require you to test with a small account first
- News-time behaviour: spreads can widen sharply around major data releases — check how each broker handles this
FCA-regulated brokers such as Pepperstone and IG both publish details on execution and account types, but the specifics change and vary by account, so always confirm current terms directly on their platforms or via [PipTax's broker pages](/brokers/index.html) rather than relying on old screenshots or forum posts.
Common Scalping Cost Mistakes
Even experienced traders fall into these traps:
- Comparing spread only — ignoring commission makes raw accounts look artificially cheap
- Using demo account fills — demo execution is often better than live, especially in volatile conditions
- Ignoring session-specific spread widening — costs during Asian session can differ sharply from London/New York overlap
- Not re-checking costs after a broker changes account tiers or pricing — cost structures do change over time
- Assuming lower minimum deposit means lower cost — these are unrelated variables
Each of these mistakes has the same effect: your actual live cost ends up higher than what you modelled, and your edge — however good the setup — quietly erodes.
Building a Cost-Aware Scalping Routine
Treat cost checking as a recurring task, not a one-off decision:
- Before opening an account: model total cost per trade using your real size and frequency
- Monthly: review actual fills versus expected cost to catch slippage drift
- After any broker pricing change: rerun the comparison — don't assume old numbers still apply
- Before adding a new pair or session to your scalping routine: check if spreads widen meaningfully for that pair/time
This routine takes minutes but protects the entire strategy. For a structured way to check pricing methodology and how PipTax gathers its comparison data, see the [methodology page](/methodology.html).
Conclusion: Put the Table Before the Setup
Scalping and broker cost decide your outcome together, but cost is the variable most traders underweight. A mediocre setup with excellent, well-understood costs can be profitable; a brilliant setup with poorly understood costs usually isn't, once real-world spread, commission and slippage are counted. Before refining your next entry rule, check the table first — run your real trade size through [PipTax's cost tool](/audit.html) and compare account types properly. Trading is risky regardless of costs, but at least make sure the cost side of the equation isn't working against you before you even place the trade.
Key takeaways
- Scalping and broker cost are inseparable — a great setup with poor execution costs still loses money over time
- Spread + commission + slippage form your real per-trade cost, not just the quoted spread
- A 0.2 pip difference in cost can wipe out a scalper's entire edge across hundreds of trades a month
- Compare raw spread + commission accounts against standard variable-spread accounts using actual trade volume, not marketing numbers
- Execution speed and requote policy matter as much as headline pricing for scalping strategies
- Use PipTax's cost tool to model your real monthly cost before committing to a broker or account type
Frequently asked questions
- Why does broker cost matter more for scalping than for swing trading?
- Scalpers take far more trades per day, so costs compound quickly. A swing trader might pay spread/commission a handful of times a week; a scalper can pay it 50-100+ times a day, so even a fraction of a pip difference multiplies into a large monthly drag.
- Is a zero-spread account always cheaper for scalping?
- Not necessarily. Zero or near-zero spread accounts usually carry a per-lot commission instead. You need to add spread plus commission together and compare that total to a standard variable-spread account's total cost for your typical trade size.
- Do all brokers allow scalping?
- Most FCA-regulated brokers, including Pepperstone and IG, permit scalping, but always check the specific account terms and execution model (market maker vs ECN/STP) since this affects fills during fast-moving news events.
- How much does slippage really cost a scalper?
- It varies by pair, session and volatility, but even small, consistent slippage on entries and exits adds up across dozens of trades. Track your actual fills versus requested price for a week to see your real slippage cost.
- What's the difference between a market maker and ECN broker for scalping?
- Market makers often quote wider spreads but no commission and fill internally; ECN/STP brokers pass orders to liquidity providers, usually with tighter raw spreads plus a commission. Neither is automatically better — it depends on your total cost and execution needs.
- Where can I check real, current costs instead of estimates?
- Use PipTax's cost audit tool to model spread, commission and typical slippage for your actual trade size and frequency, and compare broker pages for account structures before opening an account.
