Volatile Economy

Description
The mod replaces static prices at points of sale with a dynamic market economy with a simulation of supply and demand.

Mechanics
Volatile prices
Each combination of point of sale and grain type has its own independent market index within ±10% of the base price. The indices start with a small random spread - the markets are no longer identical at the beginning of the game.

Seasonal demand
Demand for crops varies by season:
Spring – high demand for rapeseed, moderate for grain
Summer is the peak demand for wheat and sunflowers
Autumn - profitable to sell corn, sugar beets, soybeans
Winter - shortage of potatoes and silage, prices rise

Competition
Each in-game month, competitors' sales are simulated from 0.5 to 8 tons per point. This creates constant supply pressure - if you don’t sell, your competitors will lower their prices for you.

Market Events
Every month, with a 100% probability, a random event from 40 available types is triggered.

HUD overlay
When approaching a point of sale, a panel appears with:
current price deviations as a percentage (green - expensive, red - cheap)
trend in the form of up, down or straight arrows
active events and remaining days
