The real trading cost is bigger than the spread
A tight advertised spread can still sit inside an expensive workflow. Compare direct trading charges, financing, conversion, execution and infrastructure costs against the way you actually trade.
Total-cost map
Difference between bid and ask. It can widen with volatility, thin liquidity, rollover or provider conditions.
Some raw/ECN-style accounts charge a separate commission per side or round turn.
Positions held across the provider's rollover time can incur a debit or credit based on instrument and account rules.
Profit/loss, commission or funding can be converted when the trade or account currency differs.
The fill price can differ from the requested price, especially during fast markets or gaps.
Market-data subscriptions, charting software, VPS, journals and evaluation fees can materially affect the economics of a trading setup.
Why leverage makes costs more important
ESMA's 2026 risk analysis highlights three ways leverage can worsen retail outcomes: it magnifies investment costs relative to capital posted, amplifies market risk, and increases the chance of forced/knock-out exits that can lead to repeated entry costs.
A 1-pip cost is not “small” simply because the margin deposit is small. Compare cost to the position's notional size and to the amount you are prepared to risk.
Example cost checklist
| Question | Why it matters |
|---|---|
| What is the normal and stressed spread? | Headline “from” spreads may not describe the conditions when you trade. |
| Is commission per side or round turn? | Comparison errors are common when account pages quote commission differently. |
| What happens at rollover? | Financing can dominate costs for trades held several days. |
| Does the account convert P/L or commission? | Conversion markups can matter for cross-currency accounts. |
| What does fast-market execution look like? | Slippage may matter more than a fractionally lower spread around news. |
