closeAllPositions

closeAllPositions()

When called, all the existing positions of the msg.sender will be closed.

emit PositionReduced

closePosition

closePosition(uint32 positionIndex)

Closes the position at positionIndex in user's positions.

emit PositionReduced

deposit

deposit(LonsShort longShort, uint128 amount, Terms term)

Users can deposit Token (or native tokens) into a pool. Deposits will be added on the Long or Short side, for the specified term.

User is charged a minimumFee which corresponds to the daily fee accrued over 50% of the position term. User's position is therefore equal to: amount - minimumFee

emit Deposit

Note: if the deposit is executed after mid update interval time (e.g. if fixings are updated every 5 minutes, the mid update interval time is 2.5 minutes), the deposit will be added to the next fixing period ⇔ amounts will be pending until the current fixing period ends. This methodology has been implemented to avoid users passing orders at near period ends.

reducePosition

reducePosition(uint32 positionIndex, uint128 amount) returns(bool hasBeenClosed)

Reduces the user's position at positionIndex, by the amount value.

If the amount is equal to position size, the position will be closed; method will return hasBeenClosed = true.

emit PositionReduced

Note: if a user reduces a position before the minimum holding period, user will be subject to a penalty fee. Furthermore, if position is generating a profit, user will receive pro-rated profit only. These processes have been implemented to force users to remain in their positions until the agreed term(s); nevertheless, any user is free to close / reduce a position whenever he wants.

Note 2: the penalty fees and non-distributed profits remain on the pool for other users to benefit from. For example, if a Long user decides to reduce (or close) a position before the agreed term, the position remainder will be left on the Long side for Short users to benefit from it. 1xMM is not earning penalty fees or non-distributed profits.
