For example, you can trace the lowest and average weekly prices over time and see when a new low price is significantly lower compared to that data set, and that set could be all time (or the past 30 days), or alternately you could just compare it to the lowest price for the previous day. But then if the price decreases slowly (eg. Every day a little less) then you will never see a big "significant" price decrease. | |
