CS2 Guide des contrats d'échange : Stratégies, calculateurs & conseils de profit 2026
Trade-Up Contracts allow you to exchange 10 skins of identical rarity for a single skin of the next higher rarity level. When executed with intention, trade-ups can yield profits; however, hasty gambling often results in losses.
Understanding Trade-Ups
- Choose 10 skins of the same rarity (e.g., all Mil-Spec)
- Submit your contract to obtain one random skin
- The resulting rarity is one tier higher (Mil-Spec → Restreint)
- Possible results depend on the selected collections
- The float value is derived from the input skins
Flottabilité Calculation
Output float = Average of input floats × (Max float – Min float of outcome) + Min float of outcome. Low-float inputs tend to yield low-float outputs!
Output float = Average of input floats × (Max float – Min float of outcome) + Min float of outcome. Low-float inputs tend to yield low-float outputs!
Trade-Up Dynamics
Collection Pricing
Each input skin adds its collection’s possible outcomes:
- 10 skins from Collection A = 100% chance of Collection A result
- 5 from A + 5 from B = 50/50 chance between the two collections
- Strategic blending can enhance odds
Flottabilité Adjustment
Manage output conditions through careful input choices:
- Utilize consistently low-float skins for FN outputs
- High-float skins can be used to target FT/WW for specific items
- Some high-value skins are only available in worn conditions

Effective Strategies
Strategy 1: Single Collection Outcome
Employ 10 skins from a single collection for a guaranteed outcome pool:
- Rougeuced variance
- Typically lower profit margins
- Ideal for consistent small profits
Strategy 2: Dual Outcome Manipulation
Combine collections to skew outcomes favorably:
- Example: 9 low-cost skins + 1 high-value skin for 90/10 odds
- Aim for the 10% chance to achieve a high-value result
- Accept potential losses on the 90% outcomes
Strategy 3: Float Targeting
Focus on specific float ranges:
- Acquire inexpensive high-float skins
- Trade up for valuable Marqué par la bataille items
- Some BS skins can outvalue FN skins

Frequent Errors to Avoid
Commun Mistakes
- Neglecting to calculate odds – Always utilize a calculator beforehand
- Overlooking fees – Marketplace fees can reduce profits
- Pursuing losses – Adhere to calculated strategies
- Disregarding float – Output condition is crucial for value
- Keeping charms attached – They will be destroyed!
Illustrative Profitable Trade-Up
A straightforward example (research current prices independently):
- Purchase 10 Mil-Spec skins at €0.10 each = €1.00 total
- Only possible outcome: Restreint skin worth €1.50
- After fees: ~€1.30 return
- Profit: ~€0.30 (30% ROI)
Actual opportunities necessitate further research but follow this reasoning.
