RexExchange

A complete server economy in one plugin. Prices move with supply and demand, players found companies and trade their shares, savings earn interest, loans come due. Everything is connected, and everything is done from menus.

Instead of stitching together a shop plugin, a stock plugin and a bank plugin, you get one system where they affect each other: inflation follows the server's money supply, overdue loans are repaid from market income, and shares count toward net worth and loan limits.

Live Market

• Every item has a stock level: buying pushes the price up, selling pushes it down, and stock slowly returns to balance
• Category tabs, trend arrows, mini price charts and stock bars on every item
• Item menu with buy/sell buttons for 1, 8, 16 and 64, each showing the exact total before you click
• Random market events: an item booms (+25-80%) or crashes for a while, announced server-wide
• Price alerts: "tell me when diamonds drop below 150", with a sound when it hits

Player Stock Exchange

• Found a company in a 3-step wizard, go public, trade shares from a menu
• Share prices move with trading and drift toward the company's real value
• Dividends paid to every shareholder by share count
• Scam-proof: a CEO can never withdraw the treasury. Money only leaves through dividends or liquidation, paid to all shareholders. Founder shares are locked for 24h after the IPO (no pump & dump)

Bank

• Savings account that earns interest every update
• Loans with a limit that grows with net worth. Miss the due date and interest doubles, half of all income repays the debt automatically, and sending money or founding companies is blocked until it's paid
• Central bank collects every tax and fee, tracks the money supply and turns it into an inflation index that scales all prices

Menus for everything

One command (/economy) opens a hub with: market, item details, stock exchange, company details, company management, bank, send money (click a player head), net-worth leaderboard, price alerts, transaction history, confirmation screens and a full admin panel (start events, stimulus, edit balances, liquidate companies, reload).
Amounts are typed in chat when needed; type "cancel" to back out.

Exploit protection

• Buy/sell spread so buy-then-sell loops always lose money
• Renamed, enchanted or lore'd items are never bought (protects crate/custom items)
• Market disabled in creative mode, armor and offhand slots are never sold
• Click cooldown against auto-clickers, menus can't be looted
