+1-1. Today is the 27th, and I will calculate your score from the 26th within 15 days, then deduct your score earned on the 11th. For example, if you didn't trade on the 26th and only earned 1 point from holding positions, but you gained 6 points from Alpha trading on the 11th, then 6 points from the 11th will be deducted, and 1 point from the 26th will be added.
