How to Unlock the Trading System
Stock Redistribution is gated behind both a progression milestone and a specific quest chain. You will not stumble into it by accident -- it requires deliberate effort to access.
Prerequisites
Authority Level 15 -- The hard gate. No amount of questing will bypass this requirement. Focus on node tasks and Protocol Spaces to level up.
Exploration Mission -- Complete "Restart Area Stock Redistribution I" from your mission log. This is a combat and exploration objective, not a story quest.
NPC Introduction -- After clearing the mission, speak with Lucky Carrot near The Hub. This conversation opens the trading interface and grants access to your first terminal.
Initial Setup
Your first terminal offers only Staple Goods -- fixed-price essentials with no profit potential. To access Elastic Goods, where real profits live, you need to spend Valley Stock Bills on your first terminal upgrade. This is a one-time investment that unlocks the entire trading mechanic.
Pro Tip: Don't Delay
Unlock trading as soon as you hit Authority Level 15. Even if you cannot afford large trades immediately, the daily price rotation means opportunities appear every reset. The sooner you start observing price patterns, the faster you develop intuition for profitable windows.
Terminal Locations
Stock Redistribution Terminals are distributed across multiple regions. Each terminal operates independently with its own upgrade track, inventory, and purchase limits.
| Region | Location | Notes |
|---|---|---|
| Valley IV | Hub Base (Worker Dorms) | First terminal; closest to starting area |
| Valley IV | Originium Science Park | Second Valley terminal |
| Valley IV | Origin Lodespring | Third Valley terminal |
| Wuling | Jingyu Valley | Uses Wuling Stock Bills for upgrades |
| Dijiang | Kernel Sector (Ship) | Accessible aboard the Dijiang vessel |
Why Multiple Terminals Matter
Each terminal has its own upgrade path and purchase limits. Spreading upgrades across terminals increases your combined daily buying capacity, which translates directly to more trading volume and more profit potential. Don't funnel all upgrades into a single location.
Understanding Elastic Goods
Elastic Goods are the heart of the trading system. Unlike Staple Goods (fixed prices, basic supplies), Elastic Goods shift in value every single day. Learning to read these fluctuations is the difference between wasting bills and making consistent profit.
Reading the Price Display
Every Elastic Goods package shows three key numbers:
Total Cost -- The price you pay to purchase the package right now. This is what leaves your wallet.
Recommended Price -- The system's reference value for the package under current market conditions. Think of it as the "fair market value."
Percentage Change -- How far the recommended price has moved from the item's baseline. This is your primary decision signal.
Interpreting the Indicators
| Indicator | Meaning | Action |
|---|---|---|
| Red arrow / negative % | Price has dropped below baseline | Favorable time to purchase |
| Green arrow / positive % | Price has risen above baseline | Favorable time to sell |
Daily Reset
All Elastic Goods prices refresh once per day at the daily server reset.
Purchase Caps
How many of each package you can buy also resets daily alongside prices.
No Expiration
Purchased goods never expire. Hold as long as you want with zero penalty.
Pro Tip: Patience Beats Volume
You do not need to buy something every day. A common trap is spending bills on mediocre deals because the system is available. Wait for days with steep percentage drops (at least -15% or deeper). A single well-timed purchase at -30% beats three purchases at -5%.
Core Trading Strategy
The fundamental approach is classic market arbitrage: acquire goods when prices are depressed and offload them when prices spike. Nothing fancy -- just discipline and timing.
Step-by-Step Process
- 1. Check daily prices -- Open the terminal and scan Elastic Goods for packages showing negative percentages
- 2. Evaluate the deal -- Compare total cost against recommended price. Good buys have recommended price significantly below total cost
- 3. Purchase selectively -- Buy packages with the deepest discounts. Skip anything near zero or slightly negative
- 4. Hold your inventory -- Purchased goods sit in your trading inventory with no time limit. Do not panic-sell
- 5. Monitor for spikes -- Check daily for packages where recommended price climbs well above total cost
- 6. Sell at peak -- When you see a favorable window, offload held goods for profit
Profit Calculation
Your margin equals the gap between your purchase price and the sell price at time of sale. The wider the spread between your buy-in percentage and sell percentage, the larger your return.
When to Skip a Day
If all packages hover near 0% change or show only mild fluctuation, save your bills. Flat days happen regularly. Trading during them yields slim margins that are not worth the expenditure.
Selling at a Friend's Terminal
This is the single most powerful optimization in the trading system. Every player receives different daily price rolls on their Elastic Goods. By visiting a friend's base, you access their price sheet -- which may show high sell prices on goods you bought cheap at home.
How Visitor Sales Work
- 1. Buy cheap at home -- Purchase Elastic Goods at your terminal when prices are low
- 2. Visit a friend's base -- Travel to their world and locate their Stock Redistribution Terminal
- 3. Sell using their prices -- If their terminal shows high positive percentages on your held goods, sell there
- 4. Both players benefit -- Your friend earns a bonus recorded in their Visitor Sales Log, even without lifting a finger. Passive income for the host.
Building a Trading Network
The more friends on your list, the more price variation you can access each day. A bigger pool means more sell-high opportunities.
Add friends actively through co-op lobbies, community forums, and social channels
Check 3-5 terminals daily for the best sell prices across your network
Coordinate with friends who play at different times for broader price coverage
It's mutually advantageous -- your visits generate passive income for the host
Pro Tip: Dedicated Trading Partners
If you find a friend whose terminal consistently rolls favorable prices, make them a priority stop. Price generation is random daily, but checking the same reliable pool of 3-5 friends saves time compared to scanning dozens of terminals.
Upgrading Your Terminals
Terminal upgrades are essential for scaling your trading operation. Each tier expands what the terminal offers and how much you can buy per daily reset.
Purchase Limits
Higher caps on how many Elastic Goods packages you can buy each day.
Expanded Inventory
New Staple Goods and Elastic Goods varieties become available with each tier.
Higher Profit Ceiling
More goods available means more chances per day to catch deep discounts.
Upgrade Currency
| Terminal Region | Currency Required |
|---|---|
| Valley IV terminals | Valley Stock Bills |
| Wuling terminals | Wuling Stock Bills |
Recommended Upgrade Order
- 1. First terminal to Level 2 -- Unlocks Elastic Goods access (essential first step)
- 2. First terminal to Level 3 -- Meaningful daily cap expansion
- 3. Second terminal to Level 2 -- Doubles your Elastic Goods access points
- 4. Spread further upgrades -- Broad coverage beats maxing one terminal early
Balancing Upgrades vs. Trading
The bills you spend on upgrades are the same bills you use for buying Elastic Goods. Early on, prioritize one or two upgrade tiers so you have enough daily buying capacity for meaningful trades. After that, alternate between upgrading and actively trading based on your bill income. A maxed terminal with zero trading capital is useless.
Stock Bill Income Sources
Trading is not the only way to build your bill reserves. Several other game activities contribute to income, and diversifying across them accelerates your overall earnings.
Outpost Orders (Primary Income)
The most consistent and productive Stock Bill farming method. Fulfilling trade requests at your outposts with factory-produced goods earns both Prosperity EXP and Stock Bills. Keep your factory lines running so you always have goods ready to trade.
Environmental Monitoring (High-Value Tasks)
Photo-based monitoring missions reward 50,000+ bills per completed task. You travel to specified locations, photograph specific creatures or landmarks, and collect a substantial payout. Time-intensive but extremely rewarding per completion.
Transport Delivery via Depot Nodes
Your Depot Node network can fulfill transport delivery requests for additional bills. Pairs naturally with factory logistics since you are already routing goods through Protocol Stashes and Depot Buses.
Income Priority Comparison
| Source | Effort | Reward | Consistency |
|---|---|---|---|
| Outpost Orders | Low | High | Daily |
| Environmental Monitoring | Medium | Very High | One-time per task |
| Transport Delivery | Low | Medium | As available |
| Elastic Goods Trading | Medium | Variable | Daily |
Common Mistakes & How to Avoid Them
1. Trading Every Day Regardless of Prices
Not every day offers good deals. Compulsively buying mediocre-discount goods wastes Stock Bills on thin margins. Wait for genuine dips -- at least -15% or deeper -- before committing bills to purchases.
2. Ignoring the Friend Terminal System
Solo trading limits you to your own daily price rolls. Checking 2-3 friend terminals per day can double or triple your returns. The few minutes spent visiting friends is the highest-value time investment in the system.
3. Dumping All Bills into Upgrades
Upgrades are important, but spending every bill on them leaves you with nothing to trade. Maintain a working balance specifically for buying discounted Elastic Goods. A maxed terminal with zero trading capital generates zero profit.
4. Selling Too Early
Holding purchased goods costs nothing -- no inventory decay or expiration. Selling at +5% because of impatience means missing days when the same goods spike to +25% or higher. Wait for a strong sell signal.
5. Never Upgrading Past Level 1
The base terminal only offers Staple Goods. Elastic Goods require at least one upgrade tier to access. Players who skip that first upgrade never even enter the trading mechanic.
6. Neglecting Alternative Bill Income
Trading alone cannot fund upgrades and purchases fast enough in the early game. Outpost Orders and Environmental Monitoring are the foundation that fuels your trading activity. Treat them as prerequisites, not optional extras.
7. Not Adding Enough Friends
Visitor trading scales directly with friend list size. A small list means fewer price options and missed high-sell opportunities. Actively expand your in-game social network -- it is a tangible economic advantage.
8. Over-Buying Staple Goods
Staple Goods serve specific purposes, but purchasing them out of habit drains bills that could fund profitable Elastic Goods trades. Only buy Staple Goods when you have a concrete, immediate need for the items they contain.
