A trading account advertised as commission-free is not necessarily cheaper than one charging a fee for every transaction. Brokers can earn revenue through the difference between buying and selling prices, explicit dealing commissions, or a combination of both. The arrangement determines where transaction costs appear and how easily clients can measure them.
When evaluating a Forex and online CFD trading broker, the account label is less informative than the complete cost of opening, maintaining and closing exposure. Five differences deserve attention because each can affect trading results in ways that a quoted minimum spread does not reveal.
Spread Markups Can Conceal the Effective Dealing Charge
A spread-based account generally incorporates part of the broker’s compensation into its bid and ask quotations. Instead of paying a separately itemized commission, the client buys at the ask and sells at the bid.
The broker may widen prices received from liquidity providers, although its actual revenue depends on its execution arrangements and hedging costs. A displayed spread of 1.5 pips does not mean the broker necessarily retains the entire amount.
During thin trading hours, spreads can expand even when the underlying market moves very little. Comparing typical spreads across active and quiet sessions provides more useful information than an advertised minimum.
Commission Accounts Can Make Costs More Visible Without Making Them Lower
Commission-based accounts often advertise tighter spreads while charging a fixed amount per traded lot or transaction. The commission may apply separately when opening and closing a position.
A narrow quoted spread can look attractive until both sides of the commission are included. Conversely, an account with a higher visible commission may still cost less if its executable spreads are consistently tighter.
The relevant calculation combines the entry spread, applicable commissions and any additional transaction charges. Account comparisons should use equivalent contract sizes and the same trading hours.
Trading Frequency Can Reverse the Cheaper Account Choice
Imagine two hypothetical accounts offering a natural gas CFD with exposure equivalent to 1,000 units per contract.
Account A charges no commission but typically quotes a $0.006 spread per unit, creating a $6 round-trip spread cost per contract if the spread remains unchanged. Account B quotes a $0.002 spread, equivalent to $2, and charges $1.50 per contract on each side. Its combined round-trip cost is $5.
For 40 completed trades, Account A incurs approximately $240 in transaction costs, compared with $200 for Account B, assuming identical sizes, quoted spreads and fills.
If Account B’s spread widens to $0.005 during the periods when orders execute, however, its combined cost becomes $8 per trade. The previously cheaper account now costs $320 across 40 trades.
Revenue Sources Extend Beyond the Initial Transaction
Some brokers also earn revenue from overnight financing charges, currency conversion markups or other account-related fees. These charges may apply under either commission-based or spread-based pricing.
For positions held over several weeks, financing can exceed the original dealing cost. A trader comparing only commissions and spreads may select the cheaper entry arrangement while overlooking the more expensive holding arrangement.
A Forex and online CFD trading broker should provide the applicable financing formula, benchmark references and administrative markups. Review those figures alongside the intended holding period rather than assuming that the account with the lowest entry cost is cheapest over time.
Execution Arrangements Influence the Meaning of Broker Revenue
Commission-based pricing does not automatically establish that every order is passed directly to an external market. Likewise, spread-based pricing does not necessarily mean the broker profits whenever a client loses.
A provider may internalize some exposure, hedge other positions or use several execution arrangements. Its revenue and risk can consequently involve dealing charges, hedging outcomes and exposure management.
The useful distinction is between disclosed pricing and actual execution quality. Slippage, rejected orders and fill consistency can outweigh a modest difference in advertised charges.
Before opening a CFD position, calculate the expected round-trip cost under both account models using the intended instrument and size. Add commissions, realistic spreads and projected financing, then compare execution policies and available trade reports to determine which pricing structure better suits the planned transactions.
