How it's calculated
Cost is lots × swap per lot per night × nights charged. Most brokers charge three nights of swap on Wednesday to cover the weekend, so each Wednesday inside your holding period adds two extra nights. Enter the swap as money per lot per night (a negative number is a cost, positive is a credit).
