Rollover Question

I'm a rank newbie and am working my way through Currency Trading for Dummies before I make any actual trades. I'm in the section that talks about rollovers (p. 56-57). If I understand correctly, if you close your position before the 5 pm deadline, then there's no rollover. However, the bank may take a couple days to pay you for your profit, if any was made?

Then there's a rollover if you didn't become square, but it could skip a day if there's a bank holiday in the country whose currency you've bought, right? I'm concerned about loss protection during rollovers. As long as you've put in for a stop loss, you're protected on the new rollover day, right?

One last thing. Is there any kind of universal guide to bank holidays available? I'm in the United States and know for sure that Christmas and Thanksgiving are bank holidays, but to be honest I haven't paid much attention to other ones and have been surprised from time to time when the bank is closed. And I'm definitely not up on holidays in Canada, Australia, European countries, etc.

Rollover is fun to talk about but in actuality, it's not really worth much. With all of the global interest rates near zero, even a good rollover would be 0.2 pips. Even in the good ol' days it was less than 3 pips and unless you are holding your position for months on end, it's not worth thinking about. Some days you are paid interest and some days you are debited. For the most part, it evens out or nearly so.

One other thing I recently learned about rollover is it is tripled on Wednesdays ... the explanation I was given is to make up for the weekend. Doesn't make sense to me, but that's the way they do it on live accounts.
