Daytrading and Taxes

I read it was 30 days after and 30 days prior(?) So in this example:

buy a stock before Nov 15, stop trading for 30 days

sell Dec 15 for a loss, do not trade for another 30 days (?)

Can anyone confirm this?

 

30 day window on both sides of each trade except for the first trade which has a one sided 30 day limit.

 

So, if you trade the stock for 11 straight months and then stop for 30 days in December -it won't change a thing- wash sale stays in place?

 

That's how I understand it. See page 56 on pub550 attached (2004 version).
