About Swap Rates

  • • Swap is the overnight interest for holding positions past 5 PM EST
  • • Positive swap = you receive credit (carry trade)
  • • Negative swap = you pay a fee
  • • Wednesday swaps are tripled (covers weekend)
  • • Rates vary by broker and are updated frequently

Finding Swap Rates in MT4/MT5

  1. Right-click the symbol in Market Watch
  2. Select "Specification"
  3. Look for "Swap Long" and "Swap Short" values
Three things to know

How rollover actually works

  1. 01

    Charged at 5pm New York time

    Swap is debited or credited at the daily rollover (17:00 ET / 22:00 GMT). Hold a position past that moment and the rollover hits — even if you closed five minutes later.

  2. 02

    Wednesday is a triple-swap day

    Most brokers triple the swap on Wednesday rollover to cover the weekend. A small daily cost can stack up fast if you hold through Wed–Fri without realizing.

  3. 03

    Direction matters

    Long the higher-yielding currency, short the lower — and you may receive interest. Reverse it and you pay. Carry trades historically chase this dynamic, but rate cuts can flip the math overnight.

Swap rates change.

Brokers update rollover rates with central bank decisions and their own funding costs. The number that's a credit today can be a charge next month — verify before relying on a positive carry as part of the strategy.
