What is a worked example of Retail Forex?

Direct answer

A “worked example” of retail Forex is a step-by-step numerical scenario that illustrates how a retail trader’s position can be valued as prices move. It lists every assumption used for the calculation—such as trade size, entry and exit prices, leverage, and estimated costs—so you can independently check the arithmetic.

Retail Forex refers to trading currency pairs through a retail-facing setup (for example, via a broker and retail trading platform), where costs and execution conditions are part of the real result.

How the worked example works

A typical worked example separates stable mechanics from variable conditions.

Stable mechanics (what the math depends on):

Position direction: long means you profit when the base currency strengthens against the quote currency; short means the opposite.
Price move: the difference between exit and entry price drives the gross profit or loss.
Contract size / pip value (defined for your assumed instrument): the same pip move can produce different currency amounts depending on lot size and the pair’s conventions.
Leverage and margin: leverage determines how much of the position is funded with borrowed capital, and margin requirements determine how much loss the account can tolerate before actions like margin calls.

Variable conditions (what changes real outcomes):

Spread and trading costs: the cost of entering and exiting affects the net result.
Execution: the actual fill price may differ from the displayed price.
Rules and jurisdiction: margin calculation and risk controls can differ by provider and location.

To keep the example verifiable, use a single consistent set of assumptions for every step.

Worked numerical scenario (with explicit assumptions)

This is a simplified scenario for explanation only; it uses assumed numbers rather than live prices.

Assumptions you can verify internally:

Account currency: USD.
Currency pair: assume a pair quoted in a way that allows you to compute pip value using the instrument’s standard conventions.
Trade size: 1.00 “lot” (you must interpret “lot” according to the instrument specification used in your own calculation).
Entry price: 1.2000.
Exit price: 1.2020.
Direction: long.
Price change: 20 pips (because 1.2020 − 1.2000 = 0.0020, and 0.0001 per pip).
Costs: assume a total spread/fee impact of 2 pips (you are explicitly assuming this, not observing it).
Leverage: assume 1:10.
Margin buffer: assume you start with enough free margin to avoid margin actions during this move.

Step-by-step mechanics:

Gross move impact: 20 pips favorable because the price increased and you are long.
Net move after costs (in pip terms): 20 pips − 2 pips = 18 net pips.
Profit/loss amount: convert the net pip value into USD using the pair’s pip value for the assumed lot size. (Because pip value depends on the instrument’s contract specifications, you must use the exact pip value rule that matches the pair and your trade size.)

What this example demonstrates:

The direction determines sign (profit vs loss).
The net result depends on both the price move and the assumed costs.
Leverage affects how much capital is tied up as margin and how quickly leverage-related risk can appear, even if the price move is not extreme.

Material limitations and failure modes

Worked examples can clarify mechanics, but they do not remove uncertainty.

At least one material limitation / failure mode:

Margin risk: leverage can turn a modest move into a large account percentage loss. If your losses expand or if you have insufficient margin, automated risk controls can restrict trading or force outcomes you did not plan.
Execution and pricing differences: the fill you actually receive may not equal your assumed entry/exit price, especially during fast markets.
Cost mismatch: your assumed 2-pip cost may not match the true spread, commissions, or other fees, so net profit/loss can differ from the scenario.

Independent verification checklist:

Confirm the instrument’s contract size and pip value rules for your exact pair and account setup.
Recalculate the pip move and net pip move from the stated entry/exit and cost assumptions.
Apply your provider’s margin and leverage rules to see how much drawdown is tolerated.
