To change/edit the parameters of an existing order From Release 1.3.10, it is possible to amend order by ClOrdID or DeribitLabel, and OrigClOrdId is not required anymore, however amending orders by OrigClOrdId is noticeably faster.

​
IMPORTANT:

  • to change the order using ClOrdID or DeribitLabel, this must be the only existing order with such ClOrdID or DeribitLabel. Multiple orders with the same ClOrdID or DeribitLabel won’t be amended that way.
  • when possible it is recommended to use faster OrigClOrdId
