你是说因为Mar.10是最后一次买入并且立刻卖掉没有持有，所以不考虑wash sale?
那如果Mar.10之后又有一次买卖会如何？原问题改成：
Last year, I had the following trades:
On March 1, I bought 500 shares at $20.
On March 2, I sold all 500 shares at $10.
On March 5, I bought 200 shares at $5, then sold them at $20 in that day.
On March 10, I bought 100 shares at $20 and sold them at $25 in that day.
On March 15, I bought 100 shares at $15 and sold them at $20 in that day.
After March 15, I had no more stock holdings or trades for the rest of the year.
Please clarify the wash sale impact, the gains/losses for each trade, and my total taxable income for these trades.
