How to Find Profitable Trade Ups
Master the CS2 trade up contract system with our advanced genetic algorithm simulator. Discover high-value contracts and maximize your returns.
What is a Trade Up?
A Trade Up Contract in CS2 allows you to exchange 10 skins (or 5 if Covert) of the same rarity for 1 skin of higher rarity from overlapping collections.
- Combine input skins of the same tier
- Receive 1 random output skin of higher rarity
- Output is from collections shared by your inputs
- Float value is calculated from input floats
Genetic Algorithm
Our simulator uses a genetic algorithm to evolve and discover optimal trade up combinations from thousands of possibilities.
- Evaluates millions of skin combinations
- Evolves contracts over generations
- Optimizes for RTP and expected value
- Finds contracts humans would miss
Lock Your Skins
Already own specific skins? Lock them to find the best contract that includes your existing items.
- Add skins you already own
- Simulator builds around your skins
- Perfect for using inventory items
- Lock up to all 10 input slots
Pro Tips for Profitable Trade Ups
Increase Search Depth
Higher depth values explore more combinations. Logged-in users can access deeper searches for better results.
Focus on Mid-Tier Rarities
Mil-Spec to Classified often have better profit margins than extremes. Start with Restricted for balanced risk/reward.
Consider StatTrak™
StatTrak contracts can yield higher profits due to price premiums, but require StatTrak inputs only.
Use Your Inventory
Lock skins you already own to find contracts that maximize value from your existing collection.
Frequently Asked Questions
Our simulator uses a genetic algorithm that mimics natural evolution. It creates a population of random contracts, evaluates their profitability, and combines the best performers to create new generations. Over multiple iterations, it evolves toward optimal solutions that maximize your expected return while considering risk factors.
Depth controls how thoroughly the simulator searches for optimal contracts. Higher depth means larger population sizes and more generations, resulting in better results but longer computation time. Logged-in users can access depths up to 200, while guests are limited to 50.
Yes! Logged-in users can switch the "Skin Source" to "Inventory" to run simulations using only skins they actually own. This helps you find the best possible contract from your current collection without needing to buy additional skins.
No, trade up contracts are inherently probabilistic. The simulator finds contracts with positive expected value (EV), meaning they're profitable on average over many trades. Individual results vary due to the random nature of CS2's trade up system. Always consider your risk tolerance and the break-even probability when making decisions.
