Here is a nifty tool to help you calculate the carry impact of a forex trade. Thanks Oanda!
Currency Interest Rates Calculator
My setups are based on monthly candle and some weekly candle breakouts. That makes out for holding positions many weeks, maybe months. Sometimes I end up having interest received, sometimes interest paid.
I see the interest paid on carry impact as a “cost of doing business”, just like taxes on capital gains.
Yay for gains!
