Content Egg > Settings > Price alerts > Price drops period. The larger this value, the more likely the discount will appear.

You can have sidebar widget with list of latest products with most big discount during special period. You can set period which will be used to compare price of product. For this, go to General settings - Price drops period. After changing this setting, wait your next price update, only after price update new setting will be applied.
