How trading costs (spread & commission) work
Every time you open or hold a leveraged CFD or forex position, you pay the market and the broker in ways that are easy to underestimate. This guide explains the main cost components in plain English so you can read a statement with more confidence. We do not publish invented spreads, invented commissions, or invented rebate percentages — those change by account type, instrument, and session.
Spread: the built-in gap
The spread is the difference between the bid (sell) and ask (buy) price quoted to you. When you buy at the ask and later sell at the bid, that gap is a cost even if the mid-market price did not move. Spreads tend to be tighter on major currency pairs during liquid sessions and wider during thin hours, rollover, or high-impact news. They also differ by instrument: a major FX pair, a metal, an index CFD, and an exotic pair will not behave the same.
Some account models include more of the broker’s compensation inside the spread. Others quote a tighter spread and charge an explicit commission. Neither model is universally “cheaper.” What matters is all-in cost for your trade size and holding period.
Commission: the explicit ticket fee
Commission is a fee charged per trade, often per lot (or notional) and sometimes per side (open and close). On commission accounts, the quoted spread may look tighter while the ticket fee shows as a separate line on the statement. When you compare brokers or account types, add spread cost and commission together for a round-turn on the instruments you actually trade. Looking at only one of the two numbers is how people fool themselves.
Overnight financing (swap)
If you hold a leveraged position past the broker’s rollover time, you may pay or receive overnight financing. The direction and size depend on the instrument, the direction of your trade, and the broker’s financing schedule. Swing traders feel this more than scalpers. Always check the contract specification and the financing line on a sample statement before you assume a multi-day hold is “cheap.”
Other costs people forget
- Currency conversion when your account currency differs from the instrument’s settlement currency.
- Deposit and withdrawal methods — some rails are free at the broker but costly at your bank; others have stated fees.
- Inactivity or platform fees if they apply to your entity and account type.
- Slippage — not a line-item fee, but a real economic cost when fills differ from the price you clicked.
A practical comparison method (no fake tables)
- Pick the three instruments you trade most.
- For each, note spread and commission on a liquid session and on a quiet session from your own platform — not from a screenshot on social media.
- Estimate round-turn cost for your typical size.
- If you hold overnight, add financing for a typical hold.
- Only then compare account types or brokers.
If a website shows a single “average spread” without time, instrument, and account type, treat it as marketing, not measurement.
Where rebates fit
Some introducing brokers or partners may share part of the partner commission with clients as a rebate. A rebate can reduce net cost, but it does not remove market risk, and it is not a profit share. ZUPIRUS may offer a fee rebate when you open through our partner link and trade — rates are announced on Discord, not invented on this page. Learn the structure in What is a trading rebate / IB program.
Standard vs commission-style accounts (conceptually)
Brokers often offer more than one retail pricing model. A “standard” style account may recover more of the broker’s revenue inside a wider spread and charge little or no ticket commission. A “raw” or “razor” style account may show a tighter spread and add an explicit commission. Marketing pages love to crown one model the winner. In practice, the winner is whichever model produces the lower all-in round-turn for your average size on your average instruments during the hours you trade.
Run a two-week notebook: for each trade, jot instrument, session, spread at entry, commission if any, and financing if held. Patterns appear quickly. Do not outsource that notebook to a stranger’s affiliate table.
News, gaps, and why “average spread” misleads
Liquidity is not constant. Around scheduled economic releases, spreads can widen sharply and slippage can dominate the cost discussion. A broker can be perfectly reasonable in quiet London–New York overlap and feel expensive for a news scalper. If your edge depends on those minutes, measure them specifically. If your edge is swing trading majors, measure your rollover hours instead.
Gaps over weekends or bank holidays are another cost-adjacent risk: a stop order is not a promise that you exit at the stop price. Risk the cash amount you can tolerate if the gap is worse than planned.
Demo versus live cost observation
Demo feeds can be useful for platform practice, but live pricing, liquidity, and financing details are what hit your equity. After you understand the buttons, move to a small live sample size solely to observe costs and process — not to “make back” anything. Keep risk tiny until your journal shows you can follow your rules.

Key takeaways
- All-in cost = spread effects + commission + financing + extras + slippage.
- Account models price the mix differently; measure with your instruments.
- Never size up because costs “feel low.” Risk management comes first — see the forex risk management checklist.
