Autobot needs building

Amazon link for games on nintendo switch https://www.amazon.co.uk/Best-Sellers-PC-Video-Games-Nintendo-Switch/zgbs/videogames/13978263031/ref=zg_bs_nav_vg_h__2_13978227031 Bot Spec: We need to record the prices of each item that is listed on ebay of all the items from the amazon link above, first on ebay we can filter and record just the 'buy it now' listings and then filter for just bid listings, for the 'buy it now' listings we need to record each price of each listing, if two sellers have the same price we just add information on the point on graph that tells us two sellers, the bot should also every hour monitor for any price changes to each listing it has recorded and then update the price on the graph as price change on same day, for bidding items we just need to put what the final bid price for when each listing has ended. For the buy it now we need to how many items have sold at each price per day. The bot should check for and update statistics every hour. Each day we need a total of the amount of products sold at each price point and then a total amount of sales for the product at the end of each day. So if 3 sellers were selling Mario for £20 and they all sold 1 each for the whole day that would be a total of £30 for the day as they had the price point so we could do 3 sold at £10 on graph as information on that point. And then at the end of each day you total all the prices as a grand total of sales for the mario game. To be able to record the statistics and price changes acccuratly i think we need to record the username of each seller so we can keep track of how they change prices for the same product.
