# update_maker_order

update_maker_order uuid (new_price volume_delta max base_confs base_nota rel_confs rel_nota min_volume)

The update_maker_order method updates an active order on the orderbook created before by setprice, and it relies on this node acting as a maker, also called a Bob node.

TIP

To prevent a user from making trades in which the transaction fees may end up costing a significant portion of the value of the trade, we have set a lower limit to the value of a trade. See the description of the volume_delta and min_volume arguments for more info.

# Arguments

Structure Type Description
uuid string the uuid of the order the user desires to update
new_price numeric string or rational (optional) the price in rel the user is willing to receive per one unit of the base coin
volume_delta numeric string or rational (optional) volume added to or subtracted from the max_base_vol of the order to be updated, resulting in the new volume which is the maximum amount of base coin available for the order, ignored if max is true; the following values must be greater than or equal to the min_trading_vol of the corresponding coin:
  • the new volume which is the max_base_vol of the order to be updated plus volume_delta
  • the product of the new volume and the argument new_price
min_volume numeric string or rational (optional) the minimum amount of base coin available for the order; it must be less or equal than the new volume; the following values must be greater than or equal to the min_trading_vol of the corresponding coin:
  • the argument min_volume
  • the product of the arguments min_volume and new_price
max bool (optional) Komodo DeFi Framework will use the entire coin balance for the order, taking 0.001 coins into reserve to account for fees
base_confs number (optional) number of required blockchain confirmations for base coin atomic swap transaction; default to base coin configuration if not set
base_nota bool (optional) whether dPoW notarization is required for base coin atomic swap transaction; default to base coin configuration if not set
rel_confs number (optional) number of required blockchain confirmations for rel coin atomic swap transaction; default to rel coin configuration if not set
rel_nota bool (optional) whether dPoW notarization is required for rel coin atomic swap transaction; default to rel coin configuration if not set

# Response

Structure Type Description
result object the resulting order object
result.base string the base coin of the order
result.rel string the rel coin of the order

result.max_base_vol string (numeric) the maximum volume of base coin available to trade; decimal representation
result.max_base_vol_rat rational the maximum volume of base coin available to trade; rational representation
result.min_base_vol string (numeric) Komodo DeFi Framework won't match with other orders that attempt to trade less than min_base_vol; decimal representation
result.min_base_vol_rat rational Komodo DeFi Framework won't match with other orders that attempt to trade less than min_base_vol; rational representation
result.created_at number unix timestamp in milliseconds, indicating the order creation time
result.updated_at number unix timestamp in milliseconds, indicating the order update time
result.matches object contains the map of ongoing matches with other orders, empty as the order was recently created
