Each deal is randomly timed 可以理解为为被动语态,表示 “每笔交易都被随机计时”,也可以把 timed 看作是作表语的形容词,解作 “每笔交易都是随机定时的”.无论属于哪种结构,意思都没有大的区别.
anywhere表示不确定的数量,意思是“大概在...之间”.另如：
The paper's circulation is anywhere from 50 to 100 thousand.报纸发行数约为五万至十万份.
His shoes cost anywhere from $200 up. 他买的鞋子总在200美元以上.
My visits lasted anywhere from three weeks to two months.我每次逗留时间从三周到两个月不等.
