| Parameter | Description | | --------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Market | Symbol & price currency of the market, as well as the exchange | | Buy/Sell Quantity | Size of each order to send | | Minimum/Maximum Position | Position bounds that the algo will not exceed. Will only send one sided orders the cumulative position reaches the minimum or maximum. | | Max Improve BBO | Most an order can be more aggressive than the current best bid or offer. Can prevent order from being too tight inside current spread. | | Position Tilt | The amount order prices should shift as a position is accumulated. For example, if MM algo net buys tokens, this will lower the price of bids & offers to fade the market. Measured in price change per unit. | | Reference Distance Fraction | Distance away from reference price to send orders. For example if Reference Distance Fraction is 0.01, the bid and offer order sent will be 1% around the current reference price (and thus 2% wide). | | Tolerance Fraction | Amount a new order would differ from current order to cancel and replace. Used to prevent flickering quotes and unnecessary cancel and replace, as well as maintaining queue priority. Measured as a fraction, i.e. not in price terms. | | Order Lockout | Minimum amount of time to wait between orders | | Fill Lockout | Amount of time to wait after a trade to send a new order | | Reject Lockout | If an order is rejected, wait this amount of time before trying again | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
