Floating price means that the ad price will fluctuate according to the market price and floating ratio. This type of price applies when bitcoin price fluctuates greatly.
When setting the floating price, such formula is used: Ad price=current market reference price* the floating ratio you set.
Example: The current market price is 35,000 CNY/BTC. If you expect to sell at a premium of 5% over the market price, you can set a floating ratio of 105%.
