Hi Clay, here's a summary of what the OPR is (from our FAQ): "The Option Premium Ratio (“OPR”) is a score attributed to our list of weekly options with the highest option premiums. The OPR is a ratio: depending on what the option’s premium is at the time of the calculation, the score will reflect the option percentage value of the underlying asset (compared on the same time, expiry and strike values). In short, the higher the OPR, the higher the returns."
