LESSON 8 / Risk

Translate a risk budget into a position

A position’s size affects how a price movement changes your account. A written risk calculation can make an assumption visible before capital is committed.

Define the scenario first

Choose an illustrative amount you are willing to expose to a particular loss scenario. Relate it to total capital and to other correlated positions. A percentage alone does not measure every risk; several positions can move together.

Use the arithmetic as a planning tool

For a simple unleveraged share example, divide a hypothetical loss budget by the planned difference between entry and exit prices. Round down if whole shares are required. This provides a planned position size under the stated assumptions, not a guaranteed maximum loss.

Test what the calculation leaves out

A gap, a lack of liquidity, slippage, fees, or a failure to execute can produce a larger loss. Options and leveraged products have additional risks that this share-based calculation does not capture. Practice with virtual capital while you learn how the assumptions connect.

Put the idea into practice.

Record a virtual position and write a second scenario with a worse exit. Compare the effect on the practice account.

Does sizing around a stop price guarantee the planned loss limit?

Review the concept

The calculation describes a scenario. Execution and market risks can change the realized outcome.
