How it works

Trading Flow

• Order Creation:
  • Users deposit tokens to the exchange
  • They can create buy or sell orders at specific price points
  • Orders are stored in the appropriate order book
• Order Matching:
  • When a new order arrives, the system checks for matching orders
  • Orders are matched at the specified price point
  • Partial fills are supported when full matches aren't available
• Settlement:
  • Matched trades are settled immediately
  • Tokens are transferred between parties
  • Service fees are collected and distributed

Fee Structure

• Fees are configurable by the deployer
• Default fee is 1% (represented as 10 in the contract)
• Fees are collected in the traded tokens
• Fees can be updated by the deployer

Price Levels

The system maintains two order books:

• Sell order book (sellOB)
• Buy order book (buyOB)

Each price level contains:

• Total volume at that price
• Linked list of individual orders
• Order metadata (seller address, amount)
