Hedging Explained: Why Locking a Position Isn't the Same as Closing It

You are long one lot of EURUSD. The position is underwater. You don't want to close it at a loss, so you open a short of the same size on the same instrument. The floating P&L stops moving. The problem feels solved.

It isn't solved. It's paused — and the pause has a price. Hedging is one of the most widely used and least precisely understood tools in retail trading, partly because the word covers two very different things: a genuine risk offset, and a locked position held because closing feels worse than waiting. This article walks through the mechanics of both, end to end.

A hedge freezes direction, not cost

When you hold equal and opposite positions in the same instrument, every pip the market moves gains on one leg and loses the same amount on the other. Net directional exposure is zero. That part is real.

What continues running underneath is everything that isn't direction.

You have paid the spread twice — once on the original trade, once on the hedging trade — and you will pay it twice more when both legs eventually close. Four crossings of the bid-ask, not two. On a tight major that's a small number. On a wider instrument during thin hours it is not.

Swap also keeps accruing, on both legs, every rollover. The long leg and the short leg attract opposite-sign swap rates, but they rarely net to zero. The difference between the two sides is a real daily cost of keeping the lock open. Hold a hedge for three weeks and that drip becomes the dominant line item in the trade.

And the original decision is still waiting for you. A locked position has deferred the choice, not made it.

Margin treatment is the part that surprises people

This is where the mechanics matter most. Many traders assume a fully hedged position consumes no margin, because net exposure is zero. That is a broker-specific and jurisdiction-specific question, not a universal rule — some account types apply reduced or zero margin on the offsetting portion, others charge margin on both legs independently.

The practical implication is the same either way: check your own margin treatment before you need it, not during a volatile session.

The reason is free margin. If both legs are charged, a hedge that was meant to protect your account has instead doubled the collateral it ties up — and your free margin, the cushion that keeps you away from a stop-out, shrinks accordingly. A position with no directional risk can still contribute to a margin event, because margin is measured against used collateral, not against net exposure.

It's also worth knowing that under some regulatory regimes, opposing positions on the same instrument are netted automatically rather than held side by side. If your account nets, there is no lock to hold — the second order simply closes the first.

A worked example (illustrative figures)

All numbers below are hypothetical, chosen for arithmetic clarity rather than to describe current market conditions.

Assume a 1.00 lot long EURUSD position — 100,000 units, roughly $10 per pip — entered at 1.1600. Price trades to 1.1540. The floating loss is 60 pips, about $600.

The trader opens a 1.00 lot short at 1.1540 instead of closing. From this point:

• Direction: frozen. If price falls to 1.1400, the long loses a further $1,400 and the short gains $1,400. Combined floating P&L stays at roughly –$600.
• Entry cost: the hedging leg crossed the spread. At an illustrative 0.8 pip spread, that's about $8 immediately, and another $8 when it closes.
• Swap: suppose the long leg pays –$7.00 per night and the short leg earns +$2.50. Net carry is –$4.50 per night. Over 14 nights, –$63. Over a month, –$135.
• Margin: at 1:100 leverage, each 1.00 lot requires roughly $1,160 of margin at that price. If your account charges both legs, used margin is about $2,320 rather than $1,160.

So after a month, the "paused" –$600 has quietly become roughly –$750 all-in, with double the collateral locked up and the original directional question still unanswered.

That is the honest arithmetic of a lock. It is not a disaster. It is simply not free, and it is not a decision.

When a hedge earns its cost

There are situations where paying that carry is a deliberate, sensible choice rather than an avoidance mechanism.

The clearest is a cross-instrument hedge, where you are offsetting a correlated exposure rather than mirroring the identical one — for example, holding a long index position and a short position in a correlated index, so you retain the spread between them while reducing broad market beta. That is a position in its own right, with its own thesis.

The second is an event hedge with a defined window. This week offers a dense cluster: RBA meeting minutes at 00:30 GMT+3 on Tuesday 13 October, Chinese inflation data at 01:30 GMT+3 and the trade balance at 03:00 GMT+3 on Wednesday 14 October, with ECB President Lagarde speaking at 02:10 GMT+3 and again at 08:30 GMT+3 the same day. US bank earnings also open the quarter's reporting season on Tuesday. A trader with a longer-horizon position who wants to carry it through a specific print, without carrying the gap risk of that single hour, may hedge the event and unwind immediately after. The defining feature is the exit plan — it exists before the hedge is placed.

What separates a hedge from a lock is not the order ticket. It's whether you wrote down, in advance, the condition that ends it.

The takeaway

Before you hedge, ask one question: what specific event or price level will cause me to remove this?

If you can answer it in a sentence, you have a hedge. If you can't, what you have is a position you didn't want to close, now costing you four spread crossings and a daily carry to avoid a decision you'll still have to make.

For most newer traders, the cheaper tool is upstream — smaller position size, so the trade never reaches the point where locking feels necessary.
