A wash sale occurs when you sell or otherwise dispose of stock or securities (including a contract or option to acquire or sell stock or securities) at a loss and, within 30 days before or after the sale or disposition, you:
Buy substantially identical stock or securities,
Acquire substantially identical stock or securities in a fully taxable trade,
Enter into a contract or option to acquire substantially identical stock or securities, or
Acquire substantially identical stock or securities for your individual retirement arrangement (IRA) or Roth IRA.
You cannot deduct losses from wash sales unless the loss was incurred in the ordinary course of your business as a dealer in stock or securities. The basis of the substantially identical property (or contract or option to acquire such property) is its cost increased by the disallowed loss (except in the case of (4) above). For more details on wash sales, see Pub. 550.
Report a wash sale transaction on line 1 or 8. Enter the full amount of the (loss) in column (f). Directly below the line on which you reported the loss, enter “Wash Sale” in column (a), and enter as a positive amount in column (f) the amount of the loss not allowed. ---------
Doesn't say you can't execute the trade. It says you can't deduct the loss. However, if all the transactions are in an IRA, you most likely won't be able to deduct a loss anyhow. Ok, there are situations where you can, but then you're getting elaborate.
