Viagogo Marketplace Repricing Tool Request

I am looking for a simple Repricing Tool for the Viagogo marketplace. It should monitor prices on a set of specific products and 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). 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.
