Section 1
Why costs decide outcomes
Two traders can follow the same strategy, take the same trades and end the year with very different results purely because of what each of them paid to trade. Costs are subtracted from every outcome: they make winners smaller and losers larger, and they do it on every single position.
The effect compounds with frequency. A trader taking one position a week barely notices a half-pip difference in pricing. A trader taking ten positions a day is paying that difference roughly fifty times a week, and it becomes one of the largest single line items in their account.
The one rule that matters
Section 2
What a spread is
Every instrument is quoted with two prices. The bid is where the market will buy from you; the ask is where the market will sell to you. The ask is always the higher number, and the gap between them is the spread.
Because you enter a long position at the ask and exit at the bid, a new trade starts slightly behind. If EUR/USD is quoted 1.0850 / 1.0852, a buy is immediately valued 0.0002 below its entry — two fractional pips. Price has to travel that distance before the position breaks even.
Spread is a cost even though it never appears as a separate charge on your statement. It is built into the quote, which is exactly why it is the cost most often overlooked.
Section 3
Fixed vs variable spreads
A variable (or floating) spread moves with market conditions. It tightens when liquidity is deep — typically during the London and New York overlap — and widens when liquidity thins, around major economic releases, at the daily rollover, and over weekends.
A fixed spread stays the same regardless of conditions. The broker absorbs the variability, and charges for that certainty by setting the fixed level above the typical variable spread. Fixed spreads can still be widened in extreme conditions; brokers reserve that right in their terms.
Neither model is universally cheaper. Variable pricing usually wins on average cost for traders active during liquid hours. Fixed pricing suits traders who value predictable execution costs, especially those trading around news or in thinner sessions.
Read the word 'typical' carefully
Section 4
Commission-based vs spread-only pricing
Brokers recover their costs in one of two ways: by widening the spread, or by passing on a rawer spread and charging a separate commission. Both are pricing choices, not indicators of quality.
| Pricing model | Typical spread | Commission | What it suits |
|---|---|---|---|
| Spread-only (standard) | From ~1.0 pip | None | Simple to read; cost is bundled into the quote |
| Raw spread + commission | From ~0.0 pip | ~$3 per lot per side | Cheaper at size; needs two-part maths |
| Fixed spread | Fixed, e.g. 2.0 pips | Usually none | Predictable, typically wider on average |
Illustrative pricing models — not live broker quotes.
The comparison only works when both parts are added together. An account showing "from 0.0 pips" with a $3-per-side commission on a standard lot costs about $6 in commission plus whatever spread was actually available. A spread-only account at 1.0 pip costs about $10. On that illustrative basis the commission account is cheaper — but at 0.4 pips of real spread the two are close, and at smaller position sizes the ranking can flip again.
Section 5
Swap and overnight financing charges
A leveraged forex position is effectively borrowing one currency to hold another, so it carries a financing charge for each night it stays open. This is the swap, and it reflects the interest-rate difference between the two currencies plus the broker's own markup.
Swap can be a debit or a credit. Holding a higher-yielding currency against a lower-yielding one may earn a small credit; the reverse pays a charge. In practice the broker's markup means debits are usually larger than the credits on the opposite side of the same pair.
Most brokers book three days of financing on one weekday — commonly Wednesday — to cover weekend settlement. A position held through that day pays roughly triple the usual amount.
When swap dominates
Section 6
Non-trading fees
These charges have nothing to do with market conditions, which is why they are easy to forget and unpleasant to discover. They are set out in the broker's fee schedule rather than its pricing page.
| Fee | How it usually works | How to limit it |
|---|---|---|
| Inactivity fee | Charged after a dormant period, often monthly | Close or fund the account deliberately |
| Withdrawal fee | Per withdrawal, sometimes waived above a threshold | Withdraw less often, in larger amounts |
| Deposit fee | Card or e-wallet processing margin | Check which funding routes are free |
| Currency conversion | Applied when the trade currency differs from the account currency | Open the account in your main currency |
For a small account these fees can matter more than pricing. An inactivity charge applied for several months to a modest balance is a far bigger proportional cost than a fraction of a pip on spread.
Section 7
Working out the all-in cost of a trade
To compare anything meaningfully, convert every component into your account currency and add them up for a complete round trip — open and close.
- Find the pip value for your position size and pair.
- Multiply the spread in pips by that pip value.
- Add commission for both sides of the trade, if your account charges it.
- Add the swap for each night you expect to hold the position.
- Express the total as money, and as a percentage of the account balance you are risking.
| Component | Illustrative calculation | Cost |
|---|---|---|
| Spread | 0.2 pip at $10 per pip | $2.00 |
| Commission | $3.00 per side, both sides | $6.00 |
| Swap (2 nights held) | $1.10 per night, illustrative | $2.20 |
| All-in round-trip cost | Spread + commission + financing | $10.20 |
Illustrative example only — one standard lot of EUR/USD, held two nights.
That single figure — roughly $10.20 in the example above — is the number worth comparing between brokers. It is also the number your strategy has to overcome before it produces anything.
Turn it into a break-even distance
Section 8
Comparing brokers honestly
A fair comparison holds everything constant except pricing: the same pair, the same position size, the same time of day, and the same expected holding period. Change any of those and the answer changes with it.
Spread
The gap between bid and ask, paid the moment you open. Widens around news and at session rollover.
Commission
A flat charge per lot, usually per side, on raw-spread and ECN-style accounts.
Swap / financing
A daily debit or credit for holding a leveraged position overnight, typically tripled once a week.
Slippage
The difference between your expected and actual fill price — not a fee, but a real cost.
Conversion
A margin applied when profits, losses or deposits move between currencies.
Account fees
Inactivity, withdrawal, or platform data charges that apply regardless of trading results.
Cost is also only one dimension. Regulation, execution quality, withdrawal reliability and platform stability all belong in the decision. The cheapest quote is worth little from a provider you cannot withdraw from.
Section 9
Common costing mistakes
- Comparing a raw-spread account's 0.0 pip headline against a standard account's spread without adding commission.
- Assuming advertised average spreads apply during news releases or the late New York session.
- Ignoring swap charges on positions intended to be held for days or weeks.
- Measuring cost in pips rather than in account currency, which hides the effect of position size.
- Forgetting that costs are paid on every trade, so high trade frequency multiplies them.
FXSpreadMeter beginner checklist
Before moving to the next lesson, I understand:
- I can explain the difference between bid, ask and spread.
- I know whether my account is spread-only, commission-based or fixed-spread.
- I can convert a spread in pips into a cost in my account currency.
- I know where my broker publishes swap rates.
- I have checked the inactivity and withdrawal fees in the fee schedule.
- I can calculate the all-in round-trip cost of a typical trade.
Apply this to real brokers
The comparison tool lists account types, spreads and commission side by side, so you can run the all-in calculation above against real pricing models.
Frequently asked questions
Is a zero-spread account actually free?
No. Accounts advertising spreads from 0.0 pips almost always charge a commission per lot instead. The cost moves from the quote into a separate line on your statement — it does not disappear.
How do I turn a spread into money?
Multiply the spread in pips by the value of a pip for your position size. On a standard lot of a US-dollar-quoted pair, one pip is about $10, so a 0.8 pip spread is roughly $8 per lot.
Why is my position losing money before the market moved?
You bought at the ask and the platform values the position at the bid. That opening gap is the spread, and price has to travel that distance before the trade breaks even.
What is a triple swap day?
Most brokers book two extra days of financing on one weekday, commonly Wednesday, to account for the weekend settlement. Holding through that day costs roughly three times the usual swap.
Do lower costs make a strategy profitable?
Lower costs improve every outcome, but they do not create an edge. A strategy that loses before costs still loses after them.
