Wednesday Triple Rollover

I'm beginning to get engrossed in trading to profit off of interest only. I have heard a few people reference to triple rollover interest on wednesdays. I'm never around the computer to watch the interest get credited to my account so I don't notice it. Is it true that we get credited/debited triple the interest on wednesdays? If so, why?

Sorry for being lazy. This new FF layout is terrific. As soon as I posted this it showed me related threads; one of which answered my question.

So we get triple on wednesday to make up for the interest we would have made over the weekend? Is this correct?

yes interest for sat and sunday are paid at the end of weds. so we get triple rate on that day.
