  • Collateral: See "Settlement Asset".
  • Commit: Placing an order to enter, exit, or flip a position in a Pool. Commits are processed at each Rebalance. If the time between a Commit and Rebalance is less than the Front Running Interval, the processing of the Commit is postponed until the next Rebalance.
  • Counterpool: the other side of the Perpetual Pool, e.g. the Short Pool is the counterpool of the Long Pool
  • Data Feed: See "Index Feed"
  • Data Manipulations: any change applied to the original oracle data before it is applied to a Perpetual Pool Market, e.g. application of a Simple Moving Average to the ETH/USD oracle feed is a Data Manipulation.
  • Deploy: Generate a new Perpetual Pool contract instance.
  • Deployer: The EOA that deploys a Perpetual Pool (account Address).
  • Effective Leverage: The real multiple of the price change that a party takes as payment. It is a function of Skew and Leverage.
  • EOA: Externally owned account.

  • Front Running Interval: The minimum time that must elapse before a commitment is executed. Trading on a Secondary Market enables instant liquidity for Pool Tokens.
  • Index Feed: An oracle wrapper that outputs the Index Price to be used for Rebalancing. Tracer uses standardised proprietary index feeds to ensure uniformity of data.
  • Index Price: The current price, or value, of the tracked market, accounting for any Data Manipulations. This is the value used in calculations at Rebalance.
  • Interval Period: See "Period".
  • Leverage: A positive integer used by the Leverage Function to amplify the transfer amount relative to the price change, e.g. 3.
  • Leverage Function: A sigmoidal function used to calculate the amount to transfer.
  • Leveraged Token: See "Pool Token".
  • Long: Party that takes payment when the price change is positive.
  • Long Balance: Market's funds belonging to the long party. ****
  • Long Pool: The side of the Market that holds the Settlement Asset backing the Long Tokens.
  • Long Token: A share of a Market's Long Balance, represented by an ERC-20 token.

  • Management Fee: A fee charged at each Rebalance. Denoted in annualised terms. Paid to the Fee Receiver.
  • Oracle: The EOA providing raw data. ****
  • Period: The time between Rebalances.
  • Perpetual Pool: The contract that holds funds and keeps account of long and short ownership. Mints Pool Tokens when funds are added and burns Pool Tokens when funds are redeemed.
  • Pool: See "Perpetual Pool" (sometimes used to refer to a "Market").
  • Pool Keeper: Various economically incentivised actions taken by third parties to support the functioning of a Market.
  • Pool Owner: The Address who owns the Market. They can set contracts to perform pool upkeep, autoclaims, and invariant checks. They can also set the Primary Fee Receiver along with the secondary fee split percentage.
  • Pool Ticker: See "Symbol".
  • Pool Token: A transferable ERC-20 token representing ownership of either long or short funds in a Market (also known as a Leveraged Token).
  • Price Feed: S_ee "Index Feed"_
  • Primary Fee Receiver: The EOA receiving part of the Management Fees, 100% of the fees if a Secondary Fee Receiver is not defined.

  • Settlement: When one side of a Pool makes a payment to its counterpool to settle the Agreement.

  • Short Balance: Market's funds belonging to the short party.
  • Short Pool: The side of the Market that holds the Collateral backing the Short Tokens.
  • Short Token: A share of a Market's Short Balance, represented by an ERC-20 token.
  • Simple Moving Average:
    ∑Pnn\frac{\sum P_n}{n}
    , where
    is a periodic data point and
    is the number of periods. Useful for smoothing volatility and reducing Volatility Decay.
  • Skew: The ratio of Market funds belonging to long and short parties. Defined as long_balance/short_balance.
