Order Properties

The BitfinexBrokerageModel supports custom order properties. The following table describes the members of the BitfinexOrderProperties object that you can set to customize order execution:

PropertyData TypeDescriptionDefault Value
TimeInForcetime_in_forceTimeInForce A TimeInForce instruction to apply to the order. The following instructions are supported:
  • DayDAY
  • GoodTilCanceledGOOD_TIL_CANCELED
  • GoodTilDategood_til_date
TimeInForce.GoodTilCanceledTimeInForce.GOOD_TIL_CANCELED
HiddenhiddenboolA flag to signal that the order should be hidden. Hidden orders do not appear in the order book, so they do not influence other market participants. Hidden orders incur the taker fee.
PostOnlypost_onlyboolA flag to signal that the order must only add liquidity to the order book and not take liquidity from the order book. If part of the order results in taking liquidity rather than providing liquidity, the order is rejected without any part of it being filled.
