Ok, so here's my scenario, and I am not sure if wash sale rule applies to all my losing trades, or some, or none. Here's the scenario: I entered into a long position of company XX on 4/10, which was closed on 5/09 for a loss of $110. I entered a similar long position with XX on 4/11 (one day after entering the previous position) and exited that on 8/17 for a loss of $549. I took up a short position on the same stock XX, half of which I covered on 9/19 for a profit, and the rest I still have opened. Can I claim the above two losses of $110 and $549 as writeoff , or does wash sale rule prohibit me from doing so since I have a similar holding opened less than a month after selling my long position. Any insight into this situation will be appreciated. The more detailed, the better. Thanks Byu1980, here are the details on my scenario again: Loss a> 100 Long XX dateOfPurchase 4/10 date Of Sale 5/9 Net Loss $110 Loss b> 200 Long XX dateOfPurchase 4/11 date Of Sale 8/17 net loss $549 profit a> 300 Short XX dateOfShortSell 9/07 date of Cover 9/19 (only 150 of 300 covered) net profit $256 *150 Short XX from 9/19 still open in 2007. Quesstion: How does Loss a and Loss b are affected, if at all by wash sale rule.
