Long / Short

By Jarosław Wasiński • Published: • Updated:
The two directions of price exposure. A long position benefits from a rise in the quoted instrument; a short position benefits from a fall, before costs and subject to the contract. In a conventional retail two-way FX quote, buying normally uses the ask and selling the bid. Long EUR/USD represents exposure to EUR strengthening relative to USD. A cash-settled currency CFD does not involve ownership or borrowing of the underlying currencies; deliverable FX and other currency instruments have different settlement and financing arrangements.
Example. For a standard EUR/USD contract, 0.10 lot represents 10,000 EUR. In a hypothetical long CFD, buying at ask 1.1000 and closing by selling at bid 1.1010 yields USD 10 before commission and financing. In a hypothetical short, selling at bid 1.1000 and buying back at ask 1.0990 also yields USD 10 before those costs. The quote sides already reflect spread, so do not deduct it again. This is settlement of a CFD price difference, not proof of physical acquisition or borrowing of EUR.

Direction and product structure

Relative currency exposure exists across different FX products, but settlement and financing differ. Identify whether the agreement involves delivery, rolling exposure, a CFD, a forward or a future. Buying and selling a CFD are not cost-free: bid/ask sides, commission and financing can differ, so net results need not be symmetrical.

Accounting for an opposite execution

A sale on a netting account can reduce a long, close it or create a net short depending on quantity. A hedging account can retain separate tickets. Before using an opposite order, establish whether the instruction closes an existing position or creates another one.

Map the currency components

Long EUR/USD and short USD/CHF both have a short-USD component, while exposing the account to EUR and CHF respectively. Reporting two different symbols does not establish diversification. Compare quantities and values in a common currency, and distinguish gross exposure from the net sensitivity to one factor.

FAQ

Does short FX always mean borrowing currencies like shorting a stock?

No. Contract structure matters: standard cash-settled currency CFDs do not require stock-style borrowing of the underlying currencies.

Can opposite orders leave separate long and short tickets?

Yes on some hedging accounts. In netting, opposite executions reduce or reverse one position.
