Buying and selling
Each buy or sell costs 1 Energy and must use a positive whole number of shares. A purchase uses personal cash and cannot exceed the unheld shares still available. A sale cannot exceed the character’s current holding.
Execution comes before impact
The trade executes at the stock’s current price. Afterward, a buy moves the quoted price upward and a sale moves it downward. Your cash proceeds or cost therefore use the pre-impact price, while the next trade sees the changed price.
Reading your portfolio
The portfolio stores shares owned and a weighted average purchase price. Buying more recalculates that average from the old position and new purchase. Selling reduces the share count but leaves the remaining position’s average purchase price unchanged.
Mechanics
How results are calculated
These rules come from the game calculation. Live market values and event-specific settings can still change the final result where noted.
Trade total
Rule
Cash cost or proceeds = current stock price × whole shares traded.
- Buying requires enough personal cash and enough shares available.
- Selling requires the character to own the shares.
- There is no partial fill in this action: the requested trade must pass the checks.
Worked example
Buying 250 shares at $40 costs $10,000 and 1 Energy. The subsequent price movement does not change that completed trade total.
Immediate price impact
Rule
Direction × min(0.5%, trade value ÷ effective market cap × 10%), with effective market cap never below $10,000,000.
- Buys use a positive direction and sells use a negative direction.
- A single trade cannot move price more than 0.5% through this rule.
- Stock price cannot fall below $1.00.
Worked example
A $100,000 buy against a $10,000,000 effective market cap moves the price up 0.1%. A large enough trade reaches the 0.5% cap.
