THE BROKER TRUTH NOBODY TELLS YOU

[Fairman]

Your Broker's Advertised Spread and Your Actual Fill Are Two Different Numbers

"0.1 pip spreads" looks great in the marketing email.

It's rarely what you actually get during live, active trading hours on a real order.

Advertised spreads are often best-case, low-volatility, low-volume snapshots — not what happens at 8:30am when NFP just printed and everyone's trying to trade the same direction at once.

Track your actual fills for two weeks. Compare them to the advertised numbers.

The gap between the two tells you more about your broker than any review site ever will.

A Dealing Desk Broker Is Not Automatically Your Enemy — But You Need to Know Which One You're Using

There's a lot of forum paranoia about dealing desk brokers "trading against" retail clients.

Sometimes that concern is legitimate. Sometimes it's overblown noise from people who lost money and needed someone to blame.

The actual useful question isn't "is my broker evil?" It's "does my broker's execution model match what my strategy actually needs?"

Scalpers generally need fast, direct execution — which points toward ECN/STP models specifically, not because dealing desks are inherently corrupt, but because the execution speed and requote risk profile matters enormously at scalping timeframes.

Know your model. Choose accordingly.

Slippage Isn't Always Against You. Check If Your Broker Gives You Positive Slippage Too.

If you're only ever tracking the times price filled worse than expected, you're missing half the picture.

Good-faith brokers pass along positive slippage as often as negative — meaning sometimes your fill is actually better than requested, not just worse.

If your fills are consistently worse and never better, that asymmetry is worth investigating and questioning directly with your broker.

If they're roughly balanced, that's actually a healthy sign of fair execution, not something to be paranoid about.

The Broker Comparison You Should Actually Be Running (And Almost Nobody Does)

Forget the marketing pages. Run this instead.

Open a small live account with two brokers you're considering. Trade the exact same strategy, the exact same setups, the exact same sizing, side by side for two weeks.

Compare actual realized spread costs, actual slippage, actual execution speed on both.

This costs a little time and a small amount of capital. It also gives you real data instead of forum opinions and marketing claims.

Most traders never do this. The ones who do rarely regret it.

Your Broker's Server Location Might Be Costing You Milliseconds That Matter

If your broker's trade servers are geographically far from the liquidity providers they route to, that physical distance translates directly into execution latency.

For a swing trader, this is genuinely irrelevant.

For a scalper, a consistent extra 100-200 milliseconds of latency, trade after trade, adds up into a real, measurable drag on execution quality over hundreds of trades.

This is a more technical consideration than most beginners think to check — but it's a legitimate factor worth researching if you're serious about optimizing execution as a scalper specifically.

Your Broker's Advertised Spread and Your Actual Fill Are Two Different Numbers

This matches what we see on the desk every London open.

Marketing “0.1” is a quiet-tape number. At 08:00–09:30 London, especially around data, the number that matters is all-in cost on your fills: spread at click + commission + any adverse slip. I keep a simple sheet for two weeks per venue — median and 90th percentile cost on EURUSD/GBPUSD only — and ignore the brochure.

One practical habit: grade setups against realised cost, not mid. A 6-pip M1 target that routinely costs 1.4–1.8 to enter/exit is a different expectancy from the backtest. Positive slip exists; I still want the distribution, not anecdotes.

Advertised vs live gap is often the cleanest broker comparison you will get without asking anyone for a favour.

Are you logging fill quality by session, or only noticing it when a day feels “expensive”?

Your Broker's Advertised Spread and Your Actual Fill Are Two Different Numbers

Marketing 0.1 and live fill at the open are different jobs. I log requested versus fill for two weeks on the pairs and hours I actually scalp — EURUSD and XAUUSD in European cash — then compare to the banner. The gap is the review that matters.

Your positive-slippage point is useful: if the broker only ever slips against you, that is data, not bad luck. Server location is a scalper tax too; milliseconds are irrelevant to swing books and expensive to M1 exits.

Frankfurt rule: demote any pair/session that charts well and bleeds on costs. I care about setup quality; I refuse to grade expectancy on mid prices I never received. Commission-plus-spread-plus-slippage is the real ticket price.

Prop angle: challenge feeds can differ from the personal account you tested. I micro-size a new firm path until the fill log looks honest.

What is your benchmark pair/session for cost — not the screenshot, the sheet?
