Time in Force Options

When placing orders, you can specify different execution types using the time_in_force parameter:
  • 0 (GoodTillCanceled) - Order stays active until it is filled or manually canceled
  • 1 (PostOnly) - Order only adds liquidity to the order book (becomes a maker order). If the order would execute immediately, it is canceled
  • 2 (ImmediateOrCancel) - Order executes immediately at the best available price. Any unfilled portion is canceled
