Mark Price : Mark Price is determined by multiplying the index price, which is the oracle price, by the price impact. As a long trader, it is favorable if the mark price is lower than the index price (=oracle price), and as a short trader, it is favorable if the mark price is higher than the index price.
Market Price : The market price is represented by the index price multiplied by the market_skew at which the trade is currently being made in merkle.trade. To be more precise, the formula would be index price*(1+MarketSkew/SkewFactor).
PnL : PnL stands for Profit and Loss and it refers to the amount of profit or loss that a trader has incurred on a particular position. Note that the PnL displayed on our frontend refers to the value excluding fees unless stated otherwise.

Slippage : Slippage is the difference between the expected price and the execution price of a trade, and is also used to prevent front-running.
Open Interest : Open interest is a total number of "future contracts" held by traders who trade on Merkle Trade. On Merkle trade, there is open interest for each of the long and short sides. The total of traders' positions on the long side is displayed as open interest (L), and the total of traders' positions on the short side is displayed as open interest (S).
Max Open Interest : Max open interest means the maximum total value of positions that can be held in each direction. The reason it exists is to protect the Merkle LP when the market is extremely skewed in a certain direction and actually moves that way.
