The Brier Score Tool aims to help you understand the working of the brier scoring algorithm. You can choose a token for which you can make a prediction if the price is going to go up or down and specify the probability of the prediction. When you click the make Prediction button, a random value of 0 or 1 is determined and based on that value the price goes up (1) or down (0). With the result for the price and the given prediction, the brier score is calculated and displayed.
