Direct answer
A worked example of Market Sell is a fully numeric scenario that shows: (1) what inputs you assume (prices, position size, fees, and account currency), (2) how the order is filled using an available current price, and (3) how you would calculate the resulting cashflows and profit/loss mechanically. Because real fills vary with market conditions, the example is not a prediction; it is a transparent demonstration of the mechanics.
Mechanism or definition
A market sell order is an instruction to sell immediately at the current available prices on the execution venue (provider/platform). Unlike a limit order, it does not define a target price; instead, the execution price comes from what is available when the order reaches the market and the broker/provider matches it.
Common terms used in examples:
- Base/quote currencies: in a pair like EUR/USD, EUR is the base and USD is the quote.
- Position size (units or lots): how much of the base currency you are selling.
- Execution price: the price at which the sell actually fills.
- Spread: the difference between available buy and sell prices; a market sell typically uses the sell side.
- Fees/costs: any commission or additional charges included in the transaction.
Stable mechanics you can illustrate without live data:
- Choose assumed sell fill price.
- Choose assumed position size.
- Compute the proceeds in the quote currency.
- Subtract any assumed fees.
- If needed, convert to account currency using an assumed conversion rate.
Evidence or example (worked scenario with explicit assumptions)
Scenario setup (all assumptions stated)
Assume you trade a forex pair where the quote currency is what you receive from selling the base (typical pair behavior). Use these assumed values for the example only:
- You place a market sell.
- Pair: BASE/QUOTE (name not required for mechanics).
- Units sold: 10,000 base units.
- Execution (fill) price you receive for the sell: 1.2000 QUOTE per BASE.
- Commission/fees: 2.00 in account currency (assume your account currency equals QUOTE for simplicity).
Cashflow calculation
- Gross proceeds from selling:
- 10,000 (BASE) × 1.2000 (QUOTE per BASE) = 12,000.00 QUOTE
- Net proceeds after fees:
- 12,000.00 − 2.00 = 11,998.00 QUOTE
Where execution price uncertainty appears
Because the order is “market,” the actual fill price may differ from what you saw before submitting due to:
- Spread at the time of execution (you effectively sell at the sell-side price).
- Slippage if available liquidity changes between your action and the fill.
To see the sensitivity, repeat only the price assumption while keeping all else identical:
- If the fill price were instead 1.1990, gross proceeds = 10,000 × 1.1990 = 11,990.00, net = 11,988.00 after fees.
- The difference between 1.2000 and 1.1990 in this setup is 10.00 QUOTE in gross proceeds (before fees), which can materially affect results.
How you would verify independently
After execution, you can verify the mechanics by checking your execution details:
- Fill price (actual execution price)
- Filled units (actual size)
- Fees/commission Then recompute the cashflows using the same formulas as above. If your account currency differs from QUOTE, you would also need an assumed or actual conversion rate used by the platform.
Limitations and risks
- Market condition variability: A market sell uses whatever price is available, so the fill price is not fixed.
- Execution costs: Spread and any commission/fees can change your net proceeds and any computed profit/loss.
- Conversion complexity: If your account currency differs from the quote currency, results depend on the platform’s conversion handling.
- Failure modes:
- Partial fills: the order may be filled in multiple parts at different prices.
- No fill / delayed execution: connectivity or low liquidity can change timing and fill quality.
- Rounding and contract specifications: lot sizing rules and minimum increments can affect the exact units used.
A worked example helps you understand mechanics, but it cannot guarantee outcomes. Historical relationships do not establish future results.
Verification or next question
If you want to make your own worked example, start with: (1) assumed fill price, (2) position size, (3) fee assumptions, and (4) whether any currency conversion is needed.
