GetCommand

Get strategy interaction commands.

    
    
    
GetCommand()

Examples

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

  • javascript
  • python
  • 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)
  

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

• For example, add a control without an input box in the strategy interaction controls, name the interaction control: buy, control description: Buy, this is a button control. Continue to add a control with an input box, name the interaction control: sell, control description: Sell, this is an interaction control composed of a button and an input box. Design interaction code in the strategy to respond to different interaction controls:

  • javascript
  • python
  • 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)
  

  
      c++
      
      
  #include <iostream>
  #include <sstream>
  #include <string>
  #include <vector>
  using namespace std;
  
  void split(const string& s,vector<string>& sv,const char flag = ' ') {
      sv.clear();
      istringstream iss(s);
      string temp;
  
      while (getline(iss, temp, flag)) {
          sv.push_back(temp);
      }
      return;
  }
  
  void main() {
      while(true) {
          LogStatus(_D());
          auto cmd = GetCommand();
          if (cmd != "") {
              vector<string> arr;
              split(cmd, arr, ':');
              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);
      }
  }
