I Have Listings with No Competitors. Do I Have the Option of the Price Not Simply Going to Ceiling?

Most definitely. The best practice in terms of repricing for products with no competition is to use the Product Sphere algorithm.

Another option is to configure the item to use the ‘Target Velocity’ repricing method. All you need to do is set a realistic daily sales target and the repricer will adjust the price of the product daily, based on it achieving, overachieving, and underachieving the target.
