exchange.CancelOrder

exchange.CancelOrder()函数用于取消订单。FMZ平台的订单Order结构中，属性Id由交易所品种代码和交易所原始订单Id组成，两者之间以英文逗号分隔。例如，OKX交易所现货交易对ETH_USDT的订单，其属性Id的格式为：ETH-USDT,1547130415509278720。

调用exchange.CancelOrder()函数撤销订单时，传入的参数orderId与订单Order结构的Id属性一致。

    
    
    
exchange.CancelOrder(orderId)

    
    
    
exchange.CancelOrder(orderId, ...args)

示例

• 撤销订单。

  • javascript
  • python
  • rust
  • cpp

  
      javascript
      
      
  function main(){
      var id = exchange.Sell(99999, 1)
      exchange.CancelOrder(id)
  }
  

  
      python
      
      
  def main():
      id = exchange.Sell(99999, 1)
      exchange.CancelOrder(id)
  

  
      rust
      
      
  fn main() {
      let id = exchange.Sell(99999, 1).unwrap();
      let _ = exchange.CancelOrder(&id);
  }
  

  
      c++
      
      
  void main() {
      auto id = exchange.Sell(99999, 1);
      exchange.CancelOrder(id);
  }
  

• FMZ的API函数中，能够产生日志输出的函数（例如Log()、exchange.Buy()、exchange.CancelOrder()等）都可以在必要参数之后附带一些输出参数。

  例如：exchange.CancelOrder(orders[i].Id, orders[i])，即在取消Id为orders[i].Id的订单时，附带输出该订单的信息，也就是orders[i]这个Order结构。

  • javascript
  • python
  • rust
  • cpp

  
      javascript
      
      
  function main() {
      if (exchange.GetName().includes("Futures_")) {
          Log("Set contract to: perpetual swap, set direction to: open long.")
          exchange.SetContractType("swap")
          exchange.SetDirection("buy")
      }
  
      var ticker = exchange.GetTicker()
      exchange.Buy(ticker.Last * 0.5, 0.1)
  
      var orders = exchange.GetOrders()
      for (var i = 0 ; i < orders.length ; i++) {
          exchange.CancelOrder(orders[i].Id, "Canceled order:", orders[i])
          Sleep(500)
      }
  }
  

  
      python
      
      
  def main():
      if exchange.GetName().find("Futures_") != -1:
          Log("Set contract to: perpetual swap, set direction to: open long.")
          exchange.SetContractType("swap")
          exchange.SetDirection("buy")
  
      ticker = exchange.GetTicker()
      exchange.Buy(ticker["Last"] * 0.5, 0.1)
  
      orders = exchange.GetOrders()
      for i in range(len(orders)):
          exchange.CancelOrder(orders[i]["Id"], "Canceled order:", orders[i])
          Sleep(500)
  

  
      rust
      
      
  fn main() {
      if exchange.GetName().contains("Futures_") {
          Log!("Set contract to: perpetual swap, set direction to: open long.");
          let _ = exchange.SetContractType("swap");
          let _ = exchange.SetDirection("buy");
      }
  
      let ticker = exchange.GetTicker(None).unwrap();
      let _ = exchange.Buy(ticker.Last * 0.5, 0.1);
  
      let orders = exchange.GetOrders(None).unwrap();
      for i in 0..orders.len() {
          // Rust不支持在CancelOrder的必要参数后附带输出参数，撤单后单独调用Log!宏输出附带信息
          let _ = exchange.CancelOrder(&orders[i].Id);
          Log!("Canceled order:", orders[i]);
          Sleep(500);
      }
  }
  

  
      c++
      
      
  void main() {
      if (exchange.GetName().find("Futures_") != std::string::npos) {
          Log("Set contract to: perpetual swap, set direction to: open long.");
          exchange.SetContractType("swap");
          exchange.SetDirection("buy");
      }
  
      auto ticker = exchange.GetTicker();
      exchange.Buy(ticker.Last * 0.5, 0.1);
  
      auto orders = exchange.GetOrders();
      for (int i = 0 ; i < orders.size() ; i++) {
          exchange.CancelOrder(orders[i].Id, "Canceled order:", orders[i]);
          Sleep(500);
      }
  }

备注

如果使用较旧版本的托管者，exchange.CancelOrder()函数的参数orderId可能与当前文档中描述的orderId有所差别。
