Spent Out Profit Ratio (SOPR)
SOPR is a metric that indicates the aggregate profits and losses realized on a particular day. It is considered a reflection of market sentiment. Both the absolute value of the indicator and the prevailing trend provide information on the behavior of market spending.
It is calculated by dividing the price you would have if you sold today against the price you had when you bought those bitcoins.
A value less than 1 indicates that current sellers are losing money and often causes a slowdown in sales, creating a support zone. More information.
