Oasis Liquidity Provider

Smart contract for populating matching-market orderbook.

linearOffers

function linearOffers(
    MarketLike otc, TokenLike baseToken, TokenLike quoteToken, uint midPrice, uint delta, uint baseAmount, uint count
) public

Adds count buy and count sell offers for trading baseToken and quoteToken to market otc by the following scheme:

• buy count: baseAmount at midPrice + count * delta
• ...
• buy 1: baseAmount at midPrice + delta
• spread: midPrice
• sell 1: baseAmount at midPrice - delta
• ...
• sell count: baseAmount at midPrice - count * delta

Takes funds from sender:

• baseToken: baseAmount * count
• quoteToken: baseAmount * count * (midPrice - delta * (count+1)/2)

The intention is that no new offers match when adding. It is up to the caller to ensure that.

function cancelMyOffers(MarketLike otc, TokenLike baseToken, TokenLike quoteToken) public

Cancels all offers created by the sender for trading baseToken and quoteToken to market otc.

Returns all funds to the sender.
