Swap
Swap as the name sound , is the interest paid for a pair of currency for overnight,
the calculation is, example ,
Currency =A , interest=5%
Currency=B, interest=3%
if the pair is A/B
If u LONG A/B, currencyA pay u 5% interest , but at the same time u need to pay currency B 3% interest, so NET, u earned 2% interest for a day
If SHORT for A/B, u pay currencyA 5%, and currency B pay 3% interest, so NET u loss 2% interest
that's just an example,
let;s take USD/JPY (US DOLLAR VS JAPANESE YEN)
USD=5.25% , JPY = 0.25%
So if u long USD/JPY, u would earn 5% daily for trading days, except saturday,sunday, but compensated back on Wednesday, where the SWAP IS TRIPPLE ( YES, times 3)
so if u short USD/JPY, u would need to pay 5% of interest .
some people , used this to make consistent swap profit to earn interest,
don;t look down at this, (for USD/JPY, one standard lot , swap/day = USD12.40)
imagine if u put there for a year , how much would that be ?
if much much higher that bank FD interest ....
the swap rate depend on the government interest rate, so the swap will be more if the interest rate between 2 currency is bigger,
a few example is
GBP/JPY , NZD/JPY , etc (becos JPY= 0.25% , the lowest among all)
