Prerequisites

• [X] I have searched for existing issues that already include this feature request, without success.

Describe the Feature Request

Amazing your code, bravo.

The point is the hability to fix the sell price as percent ONLY when the difference betwen payed price and futbin price is very high.

Describe the Use Case

So many times I get a card for 350 coins and the FUTBIN price is like 2000 coins, but finally the card doesnt sell again at that price, and in the hour that the card is in the market, the futbin price fall down, to 700 or 600 coins.

The new feature is, if the futbin price is 3, 4 or more times higher than you payed, you can sell it for a percent of futbin price. If I get a card for 350, and the futbin price is 2000 and I sell it for 1800 (90% futbin price), I will have more chances to sell it.

When you get a card for 350 and the futbin price is 500 o 600 coins, you dont want to sell for a percent of futbin price because the markup is low.

Describe Preferred Solution
