Market exposure is the total value controlled by a position, usually computed as price multiplied by the number of units held. It is distinct from position risk: exposure tells you how much value you control, while risk tells you how much you plan to lose.
How it works
For a futures contract, exposure is contract size multiplied by price. A standard WTI contract at $17.73 controls about $17,730 of exposure.
Leverage is what lets a small margin control a large exposure, which is why a modest price move can produce a large account move.
Why it matters
Exposure and risk diverge under leverage, so reporting your exposure does not describe how risky a trade is.
Thinking in exposure alone leads to sizing by how much you want to control; thinking in risk alone can miss how violently a leveraged position can move you.
A simple market example
Two traders each control $10,000 of exposure in the same asset. One has a tight invalidation and risks a few hundred dollars; the other has a wide invalidation and risks thousands. Same exposure, very different risk.
Common mistakes
Using exposure as a synonym for the amount you could lose.
Sizing a trade by desired exposure instead of by the risk budget and invalidation distance.
Frequently asked questions
Is exposure the same as potential loss?
No. Exposure is the value you control; potential loss depends on how far price can move and how your exit is set.
How is exposure related to leverage?
Leverage determines how much exposure a given amount of margin controls. More leverage means more exposure per dollar of margin.
Should I track exposure for every trade?
Yes, alongside the risk budget. Seeing them side by side keeps the gap between them visible.
