Direct answer: what to check
For dispute resolution related to forex trading, focus on the cost information that the provider publishes or commits to, and compare it to what was actually charged or reflected in confirmations. In practice, check (1) the spread definition used in your platform or agreement, (2) any explicit fees (such as commission or account charges) and how they are calculated, and (3) any non-spread pricing components that can materially affect the total cost.
A common failure is mixing up a “quoted spread” (what you saw) with the “execution spread” (what was used for the fill). Dispute resolution usually depends on which reference point is contractually defined and which inputs were used at execution.
Mechanism and definition: spreads and fees as inputs
A spread is the difference between the buy and sell price at a moment in time. For dispute purposes, you should understand whether the provider’s pricing is described as:
- Variable/market-moving pricing, where the spread can change rapidly, or
- A stated spread concept, where the agreement defines how spread is determined (even if it can still vary).
Fees are explicit charges that are separate from the spread. Examples of fee categories you may see in documents or account pricing pages include commission per trade and other account or service charges. For dispute resolution, the key question is whether the total cost you were charged matches the provider’s published fee calculation method.
Separate the items you can verify from those that may change during execution:
- Stable mechanics: definitions, calculation steps, rounding rules, and when charges apply.
- Variable execution outcomes: the actual prices available at the time of order processing, and any costs that depend on those prices.
Evidence and an example you can reproduce (with assumptions)
Use a simple “two-part” comparison:
- Published cost terms: Identify the documented spread/price basis and the fee schedule, including how charges are calculated.
- Actual records: Collect your order history, trade confirmations, and transaction statements showing the executed prices and resulting charges.
Example (illustrative assumptions, not live data):
- Assume you placed a trade at time T.
- Your platform shows a displayed spread at T_display.
- The fill is generated at T_fill using the provider’s pricing inputs.
To check for a spread dispute, compare:
- The spread implied by the executed buy/sell prices in the confirmation (spread_execution), to
- The spread concept or rule described in the published terms (spread_rule),
- Not necessarily to the displayed spread at T_display.
To check for a fee dispute, compare:
- The fee amount charged in the statement to the fee formula in the published pricing (fee_rule), using the trade details shown in the confirmation.
Limitations and failure modes to expect
Material limitations often come from mismatched reference points and system behavior. At least one common failure mode is:
- Reference-point mismatch: the displayed price/spread you saw may be different from the execution price/spread used for the fill.
Other limitations to keep in mind:
- Timing and timestamp ambiguity: time shown in different interfaces may not align, which can make it look like the “wrong” spread was used.
- Different rounding and unit conventions: fees and conversions can be calculated with rounding rules or unit bases that are not obvious from a summary view.
- Execution dependent costs: some costs scale with execution outcomes (for example, if calculations depend on executed price level), so historical patterns do not guarantee the same result later.
Because dispute resolution depends on evidence, not impressions, uncertainties should be acknowledged: without matching the agreement-defined reference points, you can’t reliably attribute the difference to a provider error.
Verification and next question to reduce ambiguity
Before submitting details for dispute resolution, you can independently verify three things:
- Where the spread is defined (the agreement or published terms) and what point it references.
- Which fees exist and how they are calculated (fee schedule and calculation method).
- Which records to compare (order history vs trade confirmation vs statement) so you do not compare incompatible views.
If you still find a mismatch, the next question is not “Was the spread wrong in general?” but “Which reference point is contractually used for the spread/price and which system record shows that same reference point for my fill?”
