你是說因為Mar.10是最後一次買入並且立刻賣掉沒有持有，所以不考慮wash sale?
那如果Mar.10之後又有一次買賣會如何？原問題改成：
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.
