GetCommand

Get the strategy's interactive command.

    
    
    
GetCommand()

Examples

• Detect interactive commands, and when an interactive command is detected, use the Log function to output it.

  • javascript
  • python
  • rust
  • cpp

  
      javascript
      
      
  function main(){
      while(true) {
          var cmd = GetCommand()
          if (cmd) {
              Log(cmd)
          }
          Sleep(1000)
      }
  }
  

  
      python
      
      
  def main():
      while True:
          cmd = GetCommand()
          if cmd:
              Log(cmd)
          Sleep(1000)
  

  
      rust
      
      
  fn main() {
      loop {
          // Rust's GetCommand() requires a timeout parameter (milliseconds) and returns Option<String>, which is None when there is no command
          if let Some(cmd) = GetCommand(0) {
              Log!(cmd);
          }
          Sleep(1000);
      }
  }
  

  
      c++
      
      
  void main() {
      while(true) {
          auto cmd = GetCommand();
          if(cmd != "") {
              Log(cmd);
          }
          Sleep(1000);
      }
  }
  

• For example, in the strategy's interactive controls, add a control without an input box, name it buy, with the control description Buy; this is a button control. Then add a control with an input box, name it sell, with the control description Sell; this is an interactive control composed of a button and an input box. Write interactive code in the strategy to respond to the different interactive controls:

  • javascript
  • python
  • rust
  • cpp

  
      javascript
      
      
  function main() {
      while (true) {
          LogStatus(_D())
          var cmd = GetCommand()
          if (cmd) {
              Log("cmd:", cmd)
              var arr = cmd.split(":")
              if (arr[0] == "buy") {
                  Log("Buy, this control has no quantity")
              } else if (arr[0] == "sell") {
                  Log("Sell, this control has quantity:", arr[1])
              } else {
                  Log("Other control triggered:", arr)
              }
          }
          Sleep(1000)
      }
  }
  

  
      python
      
      
  def main():
      while True:
          LogStatus(_D())
          cmd = GetCommand()
          if cmd:
              Log("cmd:", cmd)
              arr = cmd.split(":")
              if arr[0] == "buy":
                  Log("Buy, this control has no quantity")
              elif arr[0] == "sell":
                  Log("Sell, this control has quantity:", arr[1])
              else:
                  Log("Other control triggered:", arr)
          Sleep(1000)
  

  
      rust
      
      
  fn main() {
      loop {
          LogStatus!(_D(None));
          if let Some(cmd) = GetCommand(0) {
              Log!("cmd:", cmd);
              let arr: Vec<&str> = cmd.split(':').collect();
              if arr[0] == "buy" {
                  Log!("Buy, this control has no quantity");
              } else if arr[0] == "sell" {
                  Log!("Sell, this control has quantity:", arr[1]);
              } else {
                  Log!("Other control triggered:", arr);
              }
          }
          Sleep(1000);
      }
  }
  

  
      c++
      
      
  #include <iostream>
