[kirateckhttp]

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​

1. Base Price Mechanics
   • Every item has a configurable base price
   • Prices fluctuate randomly within set boundaries
   • Supply & Demand modifies these base calculations
2. 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
  

1. 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...
}
}
