Introduction
Hey FiveM Community! 
We’re FourTwenty, and we’re excited to share our advanced dynamic market system! This resource brings unlimited customizable markets to your server with real-time price fluctuations, modern NUI interface, and an engaging economy system. Perfect for servers looking to add dynamic trading and economic gameplay!
Core Features
Advanced Economic System 
-
Dynamic Supply & Demand
- Prices react to player trading activity
- Market prices decrease when items are sold frequently
- Prices recover over time when items aren’t being sold
- Configurable impact rates and recovery speeds
- Prevents exploitation through smart price balancing
-
NEW: Counter-Item System
- Define items that influence other items’ prices
- Example: When players craft/sell burgers, burger ingredient prices increase
- Simulates real market dependencies
- Optional per-item configuration
- Creates meaningful economic loops
-- Example Configuration { name = "Burger Bun", item = "ing_bread", basePrice = 100, counterItem = "burger", -- Optional: Define a counter item counterEffect = 0.05 -- 5% price increase per counter item }

How It Works
Supply & Demand System
-
Base Price Mechanics
- Every item has a configurable base price
- Prices fluctuate randomly within set boundaries
- Supply & Demand modifies these base calculations
-
Supply Impact
- Each sale decreases item prices
- Impact is configurable per market
- Automatic price recovery over time
supplyDemand = { enabled = true, impact = { sale = 0.02, -- 2% price decrease per sale recovery = 0.01, -- 1% recovery when not sold maximum = 0.40 -- Maximum 40% impact } } -
Counter-Item System
- Optional feature for creating economic dependencies
- When counter-items are sold/crafted, base item prices increase
- Example: Selling processed items (like burgers) increases ingredient prices
- Fully configurable effect strength and duration
items = { { name = "Salmon", item = "fish_salmon", basePrice = 85, counterItem = "sushi", -- Optional counter item counterEffect = 0.04 -- 4% price increase per sushi } } -
Price Calculation
Final Price = Base Price × (1 + Random Fluctuation) × (1 - Supply Impact + Counter Effect)- All factors are configurable
- Built-in limits prevent extreme prices
- Automatic balancing system
Market Configuration Example
["fish_market"] = {
enabled = true,
name = "Fish Market",
blip = {
sprite = 356,
color = 59,
scale = 0.8
},
location = {
coords = vector3(-1816.5, -1193.8, 14.3),
heading = 319.0,
npcModel = "s_m_m_linecook"
},
priceSettings = {
minMultiplier = 0.6,
maxMultiplier = 1.8,
maxChangePercent = 20,
supplyDemand = {
enabled = true,
impact = {
sale = 0.02,
recovery = 0.01,
maximum = 0.40
}
}
},
items = {
{
name = "Salmon",
item = "farm_salmon",
basePrice = 85,
category = "Premium Fish",
counterItem = "sushi",
counterEffect = 0.04
}
-- Add more items...
}
}
