What is a worked example of “MT5 Basics”?
A worked example is a fully spelled-out numerical scenario that uses specific, stated assumptions to show how MT5-related concepts translate into numbers. In this context, “MT5 Basics” refers to the foundational ideas a user needs to understand how an MT5 account and order logic map inputs (like trade size) to outcomes such as profit/loss representation.
A worked example should separate:
- Stable mechanics: the math and platform logic you can apply if you know the inputs.
- Variable conditions: market movement, execution quality, and account/provider settings that can change the final results.
How does a worked example of MT5 Basics work?
Think of the workflow in MT5 as converting user inputs into account impact. The key steps in an educational scenario are:
- Define the instrument and price movement (without using live data).
- Specify the trade size and how position size relates to contract units.
- Choose an exchange rate and account currency assumption (if conversion is needed).
- Decide whether to calculate:
- Unrealized profit/loss (value changes while the position is open), or
- Realized profit/loss (value is fixed when the position is closed).
- Include costs only if they are part of your stated assumptions (example: commission, financing). If you omit them, you must say so.
Material limitation: even when the mechanics are correct, execution details (spread at entry/exit, slippage, partial fills, and feed differences) can cause real outcomes to differ from the scenario.
Evidence or example: a transparent numerical scenario
Below is a worked example that focuses on mechanics and clearly marks assumptions. It does not assume real-time prices.
Assumptions (state them first)
- You trade an FX instrument quoted in which the quote currency is EUR, and the base currency is USD (pair conceptually like USD/EUR).
- Your account currency is EUR.
- You buy (open a long position) using a trade size of 0.10 “lot”.
- Assumption A1 (contract definition): 1.00 lot represents 100,000 units of the base currency. So 0.10 lot = 10,000 units.
- Assumption A2 (pip size): the instrument’s “pip” move is 0.0001 in price.
- Entry price (assumption): 1.1000.
- Exit price (assumption): 1.1050.
- Therefore price change = 0.0050.
- Pip count = 0.0050 / 0.0001 = 50 pips.
Step 1: Convert price movement into profit in account currency (mechanics)
For an educational worked example, we compute profit proportional to:
- units traded (10,000), and
- price change (0.0050), scaled by the contract/unit convention.
If the pair is structured so that profit in the account currency (EUR here) is proportional to base units × price change, then:
- Profit ≈ 10,000 × 0.0050 = 50.
Interpretation: under these assumptions, a 50-pip favorable move produces about 50 units of account currency as profit when closed.
Step 2: Where MT5 “Basics” interpretation errors happen
Even if the numeric math is right, learners commonly misread:
- Whether the scenario reflects realized vs unrealized P/L.
- Whether entry/exit prices should use bid/ask and the spread differs from your “mid” assumption.
- Whether the pip value is calculated for the specific instrument and account currency setup.
Optional extension: include costs as explicit assumptions
If you add a commission of, say, “C” and a spread cost “S” measured in account currency, then the scenario’s net result becomes:
- Net ≈ 50 − (commission C) − (spread/financing impact S), where C and S must be defined. If you do not include them, you must not claim “net profit.”
Limitations and risks (what can make the worked example differ)
At least one material failure mode is that a worked example can become misleading if assumptions are incomplete.
Common limitations to watch:
- Spread and execution mismatch: if entry and exit occur at different bid/ask levels than your assumed prices, realized P/L changes.
- Slippage and partial fills: real fills can occur at worse prices than expected.
- Contract-size differences: “lot” conventions can vary by broker/instrument specifications.
- Pip definition mismatch: some instruments can have different pip sizes or quoting decimals.
- Account settings: leverage, margin mode, and margin requirements affect whether a position can be held to the intended exit.
