Price ranges weren’t designed to help the traders. People who have played Ultimate Team for a long time know how difficult the job has become. However, in difficult times there’re always new opportunities.
It is possible to use price ranges to make coins. When the price of a card is experiencing a continuous increase, it may eventually reach its maximum value. It indicates that the price range is not well adjusted; therefore, EA will soon launch an update. In these situations, the only reason why the price didn’t keep increasing is that it wasn’t allowed to.
This way, the cards with a PRP (Price Range Percentage) above 95% are considered good investments, especially if the player has a high rating or plays in a popular league. You’ll get your return as soon as EA update the price ranges and the market starts to react to that.
However, you still have to be careful since this situation is not always valid. Just because EA will increase a price range doesn’t necessarily mean the card’s value will also increase. It’s only (almost) guaranteed for that to happen when the player’s price has already hit its maximum. Like any other trading method, this one also requires a learning/adaptation period, so don’t expect to make a lot of coins fast.
