Upload Your Inventory Now →How the Inventory Lock Tool Works
The Inventory Lock tool does what manual analysis can't — it evaluates every possible combination from your inventory:
- Upload your CSV — export from CS2 Trader extension or Steam
- Set parameters — minimum profit %, Steam fee toggle, max contracts
- Click Generate — the algorithm finds the best trade-up combo from your skins
- Skins get locked — used skins are removed from the pool
- Repeat — finds the next best combo from remaining skins
- Until done — continues until no profitable combos remain
The result: a prioritized list of every profitable trade-up contract you can make with your current inventory.
Why Auto-Discovery Matters
Most traders only see the obvious trade-ups in their inventory. The algorithm finds combinations you'd never think of:
- Cross-collection mixing: Combining skins from 3–4 collections for optimal probability weighting
- Float optimization: Using your lowest-float skins strategically for FN output targeting
- Rarity-tier scanning: Checking all tiers (Industrial through Classified) for hidden profit
- StatTrak separation: Finding ST-specific contracts alongside regular ones
How to Export Your CS2 Inventory as CSV
To use the Inventory Lock tool, you need your inventory as a CSV file:
- CS2 Trader extension: Install the Chrome extension → open your CS2 inventory → click Export CSV. This is the recommended method.
- Manual export: Create a CSV with columns: name, price, float (e.g. "AK-47 | Redline (Field-Tested)", 8.50, 0.25)
The tool automatically parses skin names, detects rarity, identifies collections, and matches float values. StatTrak™ skins are recognized automatically.
