Market Makers / Makersrefers to parties on the platform that provides liquidity to the exchange. Liquidity 'provided' by Market Makers can be 'taken' by Takers. Market Makers includes parties that place orders on Drift with the 'Post-Only' function. This means the order will be placed on the decentralised orderbook and will only add to the liquidity available. Market Makers also include parties that provide liquidity via the JIT mechanism.
Takersrefer to users on the platform that 'take' liquidity from the exchange. Takers take liquidity made available by Market Makers or Drift's AMM.
BAL providersBAL Providers are users who hold BAL Shares in a particular Perpetuals Market and increase the AMM's liquidity. These users receive positions pro-rate:e.g. their share amount of the AMM's constant product invariant (k). Adding/Removing BAL shares increases/decreases the AMM's k
Longingmeans you are speculating on the price of the asset going up.
Shortingmeans you are speculating on the price of the asset going down.
TWAPmeans Time Weighted Average Price which is the average price of the Oracle over a specified period of time. This approximation is calculated on-chain during program interactions with the account.

AMM Specific

TermDefinition
Kis the curve invariant, currently for constant product;k = base_asset_reserve * quote_asset_reserve
Base Asset Reservemeans the virtual base reserves for a market (SOL reserves).
Quote Asset Reservemeans the virtual quote reserves for a market (e.g. USDC reserves in a SOL/USDC virtual pool).
Peg Multipliermeans the magnitude of the quote asset reserve. For instance, one virtual quote asset reserve is a peg multiplier amount of the quote asset. A peg multiplier ensures that the base asset reserve and the quote asset reserve are balanced at the initialisation of the curve while ensuring that the starting price of the pool is equivalent to the oracle price of the base asset at initialisation.
Reserve Pricein the AMM, is defined as (quote_asset_reserve * peg_multiplier) / base_asset_reserve. It is the true reserves price prior to any spread logic.
Bid Priceis the Price available to sell from the AMM, before slippage.
Ask Priceis the Price available to buy from the AMM, before slippage.
Mark Pricemeans the Market Price. Average of current Bid and Ask Price.
Oracle Pricemeans the latest composite price from oracles. Oracle price is interchangeable with index price.
Repegmeans modifying the peg multiplier which means re-pegging the curve such that the mark price is closer to the oracle price.
Adjusting Kmeans modifying the curve's invariant k by scaling the base/quote asset reserves. For instance, this modifies the default slippage of a swap.
Terminal Pricemeans the mark price if all users atomically closed their positions and no repegs/k adjustments occurred (should be equal to the peg multiplier if all k adjustments were done during a balanced market).
