Each company has a pool
A Pit pool holds two reserves: KI and shares of one company. The relationship between those reserves determines the displayed share price. There is no fixed price assigned permanently to the company.
Buying shares with KI
When a player buys shares, KI enters the company pool and shares leave it. Shares become scarcer inside the pool, so the price rises during the trade. A 1% game fee is deducted from the KI input before the remaining amount is exchanged.
Selling shares for KI
When a player sells shares, shares enter the pool and KI leaves it. The added share reserve lowers the pool price. A 2% game fee is deducted from the KI proceeds before the result reaches the player’s cash balance.
Exchanging one company for another
A share-to-share exchange is routed through KI internally. The first company’s shares are converted through its pool, then the resulting value is used in the second company’s pool. Because two pools are involved, one exchange can move both prices.
Price impact
The Pit follows a constant-product market rule. A trade moves along a pricing curve, so the first unit and the last unit in a large trade may not receive the same rate. Larger trades generally create greater price impact.
Pool depth matters. The same trade can move a shallow pool more than a deep pool. Always read the preview rather than multiplying the displayed spot price by the quantity.
Seven-day share value change
The Economy graph does not show transaction volume. Its horizontal axis covers the last seven calendar days. Its vertical axis shows each day’s positive or negative percentage change in aggregate share cost.
The zero line means no daily change. Values above zero indicate an increase in aggregate share cost; values below zero indicate a decrease.
Settlement and record
A completed Pit trade updates the relevant reserves, the player’s balances, and the public Log. The preview is an estimate based on current reserves; the settled result is the final game record.
