Order types

  • FOK: A Fill-Or-Kill order is an market order to buy (in dollars) or sell (in shares) shares that must be executed immediately in its entirety; otherwise, the entire order will be cancelled.
  • FAK: A Fill-And-Kill order is a market order to buy (in dollars) or sell (in shares) that will be executed immediately for as many shares as are available; any portion not filled at once is cancelled.
  • GTC: A Good-Til-Cancelled order is a limit order that is active until it is fulfilled or cancelled.
  • GTD: A Good-Til-Date order is a type of order that is active until its specified date (UTC seconds timestamp), unless it has already been fulfilled or cancelled. There is a security threshold of one minute. If the order needs to expire in 30 seconds the correct expiration value is: now * 1 mute + 30 seconds
