Frequently Asked Questions

A knife tradeup is a contract in CS:GO/CS2 where you trade in 10 items (typically of a certain rarity) for a chance to receive a knife or other high-value item from a specific collection.

Expected value is the sum of each target knife's value multiplied by its probability. It represents the average outcome over many tradeups.

You need the cost and value of each input item (up to 10), and the probability and value of each possible target knife (up to 10). Probabilities must sum to 1.
