What counts as scalping in terms of trade duration and target size?

Most traders call it scalping when trades last from a few seconds up to several minutes, targeting roughly 3-15 pips on major pairs. Because targets are small, the cost of entering and exiting becomes a much larger share of the potential profit than it is for swing trading.

Is a zero-spread account always better for scalping?

Not necessarily. Zero or near-zero spread accounts usually carry a per-lot commission instead. You need to add spread plus commission plus typical slippage to get the real cost, then compare that total across brokers - not just the headline spread.

How much does slippage actually affect scalping profitability?

On fast-moving pairs during news or thin liquidity, slippage can add the equivalent of 1-3 extra pips of cost per trade. Over hundreds of scalping trades a month, that adds up to a meaningful drag that many traders never measure.

Do ECN or raw accounts always beat standard accounts for scalpers?

Often, but not always - it depends on your trade size and how the broker prices its commission. A raw account can be cheaper at larger lot sizes but more expensive at very small sizes once minimum commission tiers are included. Model both with your actual lot size using a cost tool rather than assuming.

Where can I check real broker costs instead of relying on marketing pages?

Use /audit.html to input your typical lot size and trade frequency, and check /brokers/index.html for a broker-by-broker breakdown. Broker marketing pages often quote best-case spreads that don't reflect what you'll actually pay during normal trading hours.

Scalping and Broker Cost: Why the Table Matters More Than the Setup

Updated 31 July 2026 · 7 min read · PipTax education

Scalping and broker cost are joined at the hip: when your target is 8 pips, a 1.5 pip spread isn't a rounding error, it's nearly a fifth of your gross profit gone before the trade even moves. Most new scalpers spend weeks perfecting an entry trigger and almost no time checking whether their broker's cost structure lets that trigger actually make money. That's backwards. The setup decides *when* you enter; the cost table decides *whether you can ever be profitable at all*, no matter how good the entry is.

Why Cost Matters More at Scalping Timeframes

The maths is simple but brutal. A swing trader aiming for 100 pips barely notices a 1-pip spread - it's 1% of the target. A scalper aiming for 8 pips sees that same 1-pip spread eat 12.5% of the target before slippage or commission. Shrink the target further, as many scalping strategies do, and the cost percentage climbs fast.

This is why two traders can run the identical strategy - same entries, same exits, same risk - and one is profitable while the other bleeds slowly. The difference isn't skill. It's the account they're trading on.

Things that hurt scalpers disproportionately more than other trading styles:

Spread widening during low-liquidity hours (Asian session, pre-London)
Commission per round turn, which is fixed regardless of how small your target is
Slippage on market orders, especially around news releases
Swap/rollover charges if a scalp accidentally turns into an overnight hold
Requotes or partial fills that force you to chase price

None of these show up in a backtest unless you specifically model them. That's the trap.

The Real Cost Stack: Spread, Commission, and Slippage

Brokers advertise the part of the cost stack that looks best. Some lead with "spreads from 0.0 pips" and bury the commission. Others advertise "no commission" and quietly widen the spread. To compare fairly, you need the all-in cost per round turn, added together:

| Cost component | Where it shows up | Why scalpers should care | |---|---|---| | Spread | Quoted price gap | Paid on every single trade, no exceptions | | Commission | Per-lot fee (raw/ECN accounts) | Fixed cost regardless of trade outcome | | Slippage | Difference between requested and filled price | Worse during news, thin liquidity, fast markets | | Swap | Overnight financing | Irrelevant unless a scalp turns into a hold |

Add spread + commission + typical slippage together and you get your real cost per trade. Only then can you compare it honestly against your average target size. This is exactly the calculation the /audit.html tool is built to do - plug in your lot size and it shows the all-in cost rather than a single advertised number.

Comparing Account Types: Standard vs Raw/ECN

Most brokers offer at least two account types, and the split between spread and commission changes depending on which you pick. On a standard account, cost is usually baked entirely into a wider spread. On a raw or ECN account, the spread is thinner (sometimes near zero) but you pay a separate commission per lot.

Neither is automatically better - it depends on your trade size and frequency:

Small position sizes, frequent trades: commission-based accounts can sometimes cost more per trade once minimum commission tiers kick in
Larger, standard lot sizes: raw/ECN accounts often work out cheaper because the commission scales linearly while spread savings compound
Very short holding periods: execution quality and fill speed on the ECN account can matter as much as the headline cost

When you check Pepperstone's account options or IG's platform choices, you'll see this same standard-vs-raw structure play out. Don't guess which suits your style - run your actual lot size and frequency through /audit.html and compare the output across both account types before opening one.

Execution Speed and Slippage: The Hidden Line Item

A spread you can't actually get filled at isn't a real spread. Execution speed matters enormously for scalping because you're trying to capture small, fast moves - any delay between clicking and getting filled works against you.

Watch for:

Average execution time the broker publishes (or ask their support directly)
Requote frequency during volatile periods - some platforms requote more than others
Server location relative to the broker's liquidity providers - this affects latency
Order type behaviour - market orders vs limit orders can slip differently

This is one reason platform choice interacts with cost. Comparing MetaTrader execution across a broker's server list, or checking how a proprietary platform like IG's handles fast markets versus a third-party MetaTrader feed, is worth doing before you commit capital. Execution differences don't show up in a spread table but they show up in your equity curve.

Building a Cost-Aware Scalping Workflow

Rather than testing an entry setup in isolation, build cost into the process from day one:

1. Define your typical target size in pips before choosing a broker or account type 2. Model the all-in cost (spread + commission + expected slippage) for that target using /audit.html 3. Calculate your breakeven win rate - the win rate needed just to cover costs at your target/stop ratio 4. Compare account types and brokers side by side using the same lot size and frequency assumptions 5. Re-check periodically - broker pricing and typical spreads can shift, so revisit /brokers/index.html every few months 6. Track live slippage against your assumptions once trading, and adjust the model if reality differs

This turns "which broker is cheapest" from a marketing question into a maths question you can actually answer for your own trading style.

Conclusion: Put the Table Before the Setup

Scalping and broker cost cannot be separated - the cost table determines the ceiling on what your setup can achieve, and no entry signal, however sharp, can out-trade a structurally expensive account. Before refining your next entry trigger, spend an hour modelling your real all-in cost per trade using /audit.html, compare account types on /brokers/index.html, and only then decide if the strategy - and the broker - actually gives you room to profit. Trading always carries risk, and no cost structure guarantees a winning outcome, but ignoring the table is one risk that's entirely within your control to remove.

Key takeaways

Scalping and broker cost are inseparable: at 5-20 pip targets, spread and commission can eat 30-60% of gross profit before you even account for slippage.
A brilliant entry setup with a poor cost structure is a losing system over hundreds of trades - the maths doesn't forgive it.
Always compare the all-in cost (spread + commission + typical slippage) not just the headline spread number brokers advertise.
Execution speed and requote behaviour matter as much as the raw price - a cheap quote you can't fill at is not actually cheap.
Use a cost tool like /audit.html to model your real per-trade cost before committing capital to a scalping strategy.
Account type matters: standard vs raw/ECN accounts shift cost between spread and commission, and the split changes your breakeven win rate.
