BTSE Important Update

On May 29, 2024, BTSE will be changing parameters for the following APIs to include a new field: contractSize in their response data:


  • GET /api/v2.1/order
  • GET /api/v2.1/user/open_orders
  • GET /api/v2.1/user/positions
  • GET /api/v2.1/user/trade_history



  • allPosition
  • Positions
  • fills


This API will respond to users with the new contractSize number of the respective market

  • GET /api/v2.1/market_summary


These API changes are designed to set the groundwork for future changes in futures contract sizes. While the API changes will occur on May 29, 2024, changes in futures contract sizes will occur at a later date. We will notify you when this occurs.
