# TradingPool

**TradingPool** is at the heart of the TRADE module. It defines a liquidity pool where NFTs and a designated token (e.g., SUI or another fungible token) interact.

**Key Fields**:

* `id`: A unique identifier for the pool.
* `collection_id`: Identifies which ART20 collection the NFTs belong to.
* `nft_reserve`: The count of NFTs held in the pool.
* `token_reserve`: A balance of the fungible tokens paired with the NFTs.
* `lp_supply`: A supply object representing the total amount of LP tokens minted.
* `lp_shares`: Balance of LP tokens representing liquidity provider shares.
* `fee_percent`: The fee charged on trades, distributed among LPs and possibly the pool creator.
* `min_price` / `max_price`: Bounds to ensure pricing remains within a certain range.
* `is_active`: Indicates if the pool is currently operational.
* `accumulated_fees` / `contract_owner_accumulated_fees`: Track accumulated and undistributed fees.
* `nft_holdings`: A table storing the NFTs pooled within the TradingPool.
* `last_trade_price`: The most recent trade’s price, aiding in historical data and price impact calculations.

**Role**:

* Facilitates instant buy/sell actions.
* Maintains a price curve based on reserve ratios.
* Emitted events track every trade and liquidity change.
