Exposure and margin are different
Risk includes the impact of an adverse move, how an exit is executed and what happens if the market or platform behaves differently from expectations. Leverage allows large exposure relative to funds committed and magnifies the effect of price movements.
Futures margin supports contractual obligations; it is neither the full price of the instrument nor an automatic cap on losses. Requirements may change. A protective order also does not guarantee execution exactly at the intended threshold.
Define a bounded exercise
Synthetic example: a contract is worth 2 units per point and the assumed adverse move is 5 points. The estimate is 10 units before costs; with three contracts it would be 30. This calculates a scenario, not the worst possible outcome: price gaps or different execution are absent, for example.
For practice, set the permitted quantity, duration, maximum decisions and stopping condition. Limits should support learning a skill. Do not treat a universal percentage as a substitute for understanding the instrument and the exercise’s rules.
Check before acting
Mentally test a scenario worse than the expected one. If you cannot explain its effect or how to stop the exercise, return to units and orders. You can pause practice to understand a detail; it does not need to become a competition.
- Record exposure and execution assumptions.
- Define the situation that will make you stop and review.
- Move on when you can explain why an estimated loss is different from a guaranteed loss.

ACTIVITY · AT YOUR OWN PACE
Apply the idea before continuing
Write your answer before opening the reasoning. All prices, quantities and outcomes in this activity are hypothetical. Keep your explanation in your own notebook; it is not sent to the server.
The case
You practise with 3 contracts worth 2 units per point. You estimate a 5-point adverse move; the hypothetical fill ultimately occurs 8 points from entry.
Your task
Compare the estimated loss and the loss at that fill, before costs. Explain why the planned level does not guarantee the final amount.
Compare my answer with the reasoning
The estimate was 5 × 2 × 3 = 30 units; the fill implies 8 × 2 × 3 = 48. The difference is 18 before costs. A calculated scenario is not a guaranteed loss cap. Required margin does not determine that loss either.
Evidence you should be able to explain
Two calculated scenarios, an execution assumption and a condition for stopping practice.
If you cannot justify it, revisit the example and state what is missing. A memorised answer or simulated profit does not replace this explanation.
