Understand the topic
A trading platform displays prices, quantities, balances and percentages together, but those numbers describe different things. A pip measures a price change. A lot describes a quantity under a contract specification. Notional exposure expresses the size of an economic position. Margin is collateral required under a particular account and instrument model. Reading one as another can produce an incorrect support answer, an inconsistent report or an unsuitable acceptance test. This collection explains the calculations with explicit units so that operators can check a displayed result against the underlying specification.
Begin with price precision and quantity. The pip and pipette reference separates a conventional forex price increment from an extra displayed decimal. The lot-size reference then connects a platform quantity to contract units. Together, those inputs allow the pip-value worksheet to calculate a monetary change. Where the quote currency differs from the account currency, the conversion step is shown separately. A number without its currency, contract size and applicable conversion rate is incomplete, even when the arithmetic itself looks plausible.
The next group examines exposure and collateral. Notional value helps describe the position being carried; it is not automatically the money deposited or the maximum possible loss. The leverage and margin worksheet uses a deliberately simple model before identifying conditions that require a different calculation. Free margin and margin level explain two different views of the same account state. The margin-call and stop-out reference then separates a warning or restriction state from a close-out process. Actual thresholds, calculation modes and close-out behavior must come from the relevant account terms and platform configuration.
Balance, equity and overnight financing complete the operational picture. Open profit and loss can change equity while balance remains unchanged. Credits, blocked amounts and posted charges may also affect the values shown. Swap or rollover costs add a separate calendar and contract-specification dependency. A charge expressed in points cannot be treated as a currency amount without the appropriate conversion, and a multi-day multiplier should never be assumed solely from the day of the week. The examples make those dependencies visible rather than hiding them inside a single result.
These pages are educational references for brokerage teams, platform users and implementation reviewers. They use synthetic figures, not account recommendations or observations of a deployed FxTrusts system. Each page provides a worked example, common interpretation errors and a short verification checklist. Follow the linked primary documentation for the actual instrument and platform being assessed, then use the related references to investigate the next calculation in the chain. For product evaluation, connect these checks to the platform demonstration and written implementation scope. Neither a correct formula nor a familiar trading-platform label establishes market availability, regulatory permission or suitability for a particular customer.
