Volatile Economy

# Volatile Economy - Farming Simulator 25 Mod

## 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 × type of grain” has its own independent market index (±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 - peak demand for wheat and sunflower

- Autumn - it is profitable to sell corn, sugar beets, soybeans

- Winter - shortage of potatoes and silage, prices rise

### 👨‍🌾 Competition

Every 6 game hours, sales of competitors are simulated (0.5–8 tons per point). This creates constant supply pressure - if you don’t sell, your competitors will lower their prices for you.

### 💥 Player Offer Shock

When you sell a large volume at a time, the price at that point immediately decreases (the effect depends on the number of tons). Sell ​​in small quantities to different locations for better profits!

### 📰 Market events (10 types)

Every month there is a 100% chance that a random event will be triggered.

### 📊 HUD overlay

When approaching a point of sale, a panel appears with:

- Current price deviations (%, color: green=expensive, red=cheap)

- Trend (↑↓→)

- Active events and remaining days
