How to Tell If Forex Swap Is Positive or Negative

Direct answer

To find whether forex swap is positive or negative, compare your position direction (long/buy or short/sell) with the instrument’s published overnight swap/rollover rates for that direction. If the rate applied to your side results in a credit to your account overnight, the swap is positive; if it results in a debit, the swap is negative. Because brokers can use different conventions and formulas, the only reliable “sign” is the one your broker applies in its own swap/rollover documentation or account statement entries.

How it works (what you need to check)

Forex “swap” in this context usually means the broker’s overnight financing/rollover adjustment for holding a position past the broker’s daily rollover time. The key inputs are:

1. Your trade direction: A buy (long) and a sell (short) on the same currency pair are typically treated differently for overnight financing.

2. The currency pair’s rollover rates: Many brokers publish a swap table that lists swap amounts (or points) for each pair and for each direction.

3. The swap timing convention: Swap is applied when your position crosses the broker’s rollover cutoff. Holding across that cutoff is what triggers the overnight financing adjustment.

Practical rule: If your broker’s table shows a value for your side that is marked as a credit (or appears as a positive addition in your account history), that is effectively positive swap. If it shows as a debit (or a negative adjustment in your statement), it is negative swap.

Example checks and verification steps

1. Read the broker’s swap/rollover table for your exact instrument

   • Locate the currency pair.
   • Find the row/column that matches the position side (buy vs sell).
   • Note the sign as presented by your broker (some show “swap points,” others show cash amounts).

2. Confirm using an account statement entry

   • After a day where the position is held across the rollover cutoff, review the overnight swap/rollover line item in your account history.
   • If the entry is an addition to your balance/equity, it matches positive swap. If it reduces your balance/equity, it matches negative swap.

3. Re-check when any input changes

   • Different brokers may publish swap in different units or conventions.
   • Broker-applied swap can be updated over time due to policy or rate changes, so the sign can change later.

Relevant limitations and risks

• Provider-dependent details: The swap “sign” is determined by your broker’s published terms and how it records overnight financing. Two brokers may display different values and even different units.
• Time uncertainty: Swap rates can change, so a sign observed today may not hold tomorrow.
• No real-time guarantee: Without checking the broker’s current swap table or your own statement entries, you cannot reliably infer the exact sign for your account at this moment.
• Risk from costs: Overnight swap/rollover is a recurring financing effect tied to holding time; it can increase or decrease the net result of a position.

If you want, share the currency pair, whether you’re long or short, and the broker’s swap table values you’re looking at (buy-side and sell-side). I can help interpret which side corresponds to positive or negative based on the broker’s conventions.
