Viagogo Marketplace Repricing Tool

I am looking for a simple Repricing Tool for the Viagogo marketplace. It should monitor prices on a set of specific products and automatically adjust the price so it is one cent lower than the lowest price (if the other seller qualifies as competition for the best price button). If the price increases then it should also increase it to still be one cent below. It should be able to follow a few rules like min/max price, cool down (when too many repricings in a period of time happen), botvsbot, no repricing when out of stock and should be able to send notifications when a trigger is hit. Also a counter for how many repricings were made would be nice.
