Before you begin

Work from the hypothetical budget and contract terms in each question. Chosen risk percentages are arithmetic inputs, not recommendations. A calculated loss allowance assumes the stated fills and costs; ordinary stops, gaps and changing conditions can produce a larger realised loss.

Exercise 1 · Hypothetical example

Calculate the lot quantity for this model. Enter lots to two decimal places.

Hypothetical USD account equity is 5,000. The exercise allocates 0.8% to a modelled loss. EUR/USD entry-to-stop distance is 25 pips, pip value is USD 10 per pip per 1.00 lot, and one lot represents 100,000 EUR. Ignore additional costs and slippage for this first calculation. Available size step is 0.01 lot and minimum is 0.01 lot.

Enter your answer in lots

Enter 2 decimal places, following the rounding rule in this exercise. Use a decimal point and no thousands separators.

Exercise 2 · Hypothetical example

Calculate the largest permitted lot quantity within the stated modelled budget. Enter lots to two decimal places.

Hypothetical budget: USD 50. Stop distance: 18 pips. Pip value: USD 10 per pip per full lot. Additional round-trip commission: USD 7 per lot. Minimum and size step: 0.01 lot. The entry-to-stop price distance already uses the assumed executable prices; do not add the same spread twice. No other costs or slippage are modelled.

Enter 2 decimal places, following the rounding rule in this exercise. Use a decimal point and no thousands separators.

Exercise 3 · Hypothetical example

Which maximum lot quantity treats the fixed reserve in the correct units?

Hypothetical total budget is USD 35. Reserve a fixed USD 5 for the whole trade, independent of quantity. The assumed stop distance is 20 pips and pip value is USD 10 per pip per lot. Sizes use a 0.01-lot step and minimum. No additional per-lot fee is included. Keep the full fixed reserve even if the trade is smaller.

Choose the interpretation supported by the information given

Exercise 4 · Hypothetical example

What conclusion follows without changing the stated plan or budget?

A hypothetical modelled loss budget is USD 3. Stop distance is 50 pips and pip value is USD 10 per pip per full lot. The product’s minimum quantity and step are 0.01 lot. Ignore additional costs for this calculation. The stop represents the chosen invalidation condition and must not be moved solely to make the size fit.

Exercise 5 · Hypothetical example

Calculate the largest permitted gold lot quantity within this modelled budget. Enter lots to two decimal places.

Hypothetical XAU/USD long entry is USD 2,350 per troy ounce and the assumed stop fill is USD 2,342. This example’s contract is 100 troy ounces per 1.00 lot. Budget is USD 80, additional round-trip commission is USD 4 per lot, and minimum/step are 0.01 lot. Prices already reflect the assumed execution; no further spread, financing, conversion or slippage is modelled. Actual contract terms vary.

Enter your answer in lots

Enter 2 decimal places, following the rounding rule in this exercise. Use a decimal point and no thousands separators.
