This page provides a simple explanation of some of the more common terms used in DeFi.

Term	Description
Candle Chart	A candle chart, is a type of financial chart used to represent the price movement of an asset over time. The chart displays four key pieces of information for each selected time period: the opening price, the closing price, the highest price, and the lowest price. Each time period is represented by a rectangle with a "wick" above and below it, resembling a candlestick. The top and bottom of the rectangle represent the opening and closing prices, with the body of the rectangle filled green if the closing price is higher than the opening price, and red if the opening price is higher than the closing price. Candle charts are popular among traders and investors because they provide a visual representation of price movements and can help identify patterns and trends that may be useful in making trading decisions.
Collateral	Collateral is any asset which a borrower must provide to take out a loan, acting as a security for the debt.
Limit Price	A limit price refers to the specific price at which a trader is willing to buy or sell a particular token. It is the maximum or minimum price that the trader is willing to pay or receive and the order will only be executed if the market reaches that price or better. Limit orders can be used to control the price at which a trade is executed and can be useful for managing risk or maximising profit potential.
Liquidation Price	Liquidation Price is the price at which the (collateral - losses - borrow fee) is less than 1% of the position's size. If the token's price crosses this point then the position will be automatically closed.
Long Order	A long order is a trading order to open a trading position that will earn a profit if the token's price goes up and will make a loss if the token's price goes down.
Market Price	The market price is the current price at which a token is being bought or sold. It is the most recent price provided by the active price feeds.
MLP	The Meridian Liquidity Pool is the multi-asset liquidity pool for both zero slippage swaps and leveraged trading. Users deposit USDC, USDM, and ETH into the MLP pool in exchange for MLP tokens and an ongoing share of the protocol rewards. MLP tokens can be redeemed at any time for any of the tokens in the pool.
Open Orders	Leverage Trading orders that are not yet active but are awaiting execution. These orders will become active, open positions when certain predefined conditions are met.
Open Positions	Leverage Trading orders that have already been placed and where trading positions are currently active.
Orders Table	The Orders Table shows all currently Open Trading orders that are not yet active but are awaiting execution.
Positions Table	The Positions Table shows all currently active positions that the trader is exposed to in the market.
Long Order	A long order is a trading order to open a position that will earn a profit if the token's price goes up and will make a loss if the token's price goes down.
Short Order	A short order is a trading order to open a position that will earn a profit if the token's price goes down and will make a loss if the token's price goes up.
Swap Order	Swap orders trade one token directly for another token using the multi asset liquidity pool. However, unlike when using traditional AMM protocols Meridian completes swaps with zero slippage.
Trigger Price	A trigger price refers to a specific price point that, when reached, triggers the execution of a buy or sell order. It can be used to manage stop-loss and limit orders where the trigger price acts as a pre-set condition for the order to be executed. When the trigger price is reached, the order is sent for execution, and the trade is executed at the best available price. Trigger prices can be used to manage risk or take advantage of price movements in the market.
