Penggunaan Plugin

Plugin boleh menjalankan kod untuk tempoh masa, dan ia boleh melakukan beberapa operasi mudah, sepertiPerintah aisberg, Perintah menunggu, pembatalan pesanandanPengiraan pesananSama sepertialat debugging, ia menggunakanreturnuntuk mengembalikan hasil, dan ia juga boleh secara langsung mengembalikan carta dan jadual. Berikut adalah beberapa contoh, dan fungsi lain boleh diterokai sendiri.

• Kembali ke snapshot kedalaman

  // Return to the depth snapshot
  function main() {
      var tbl = { 
          type: 'table', 
          title: 'snapshot of the order depth @ ' + _D(), 
          cols: ['#', 'Amount', 'Ask', 'Bid', 'Amount'], 
          rows: []
      }
      var d = exchange.GetDepth()
      for (var i = 0; i < Math.min(Math.min(d.Asks.length, d.Bids.length), 15); i++) {
          tbl.rows.push([i, d.Asks[i].Amount, d.Asks[i].Price+'#ff0000', d.Bids[i].Price+'#0000ff', d.Bids[i].Amount])
      }
      return tbl
  }
  

  def main():
      tbl = {
          "type": "table",
          "title": "snapshot of the order depth @ " + _D(),
          "cols": ["#", "Amount", "Ask", "Bid", "Amount"],
          "rows": []
      }
      d = exchange.GetDepth()
      for i in range(min(min(len(d["Asks"]), len(d["Bids"])), 15)):
          tbl["rows"].append([i, d["Asks"][i]["Amount"], str(d["Asks"][i]["Price"]) + "#FF0000", str(d["Bids"][i]["Price"]) + "#0000FF", d["Bids"][i]["Amount"]])
      return tbl
  

  void main() {
      json tbl = R"({
          "type": "table",
          "title": "abc",
          "cols": ["#", "Amount", "Ask", "Bid", "Amount"],
          "rows": []   
      })"_json;
      
      tbl["title"] = "snapshot of the order depth @" + _D(); 
      auto d = exchange.GetDepth();
      for(int i = 0; i < 5; i++) {
          tbl["rows"].push_back({format("%d", i), format("%f", d.Asks[i].Amount), format("%f #FF0000", d.Asks[i].Price), format("%f #0000FF", d.Bids[i].Price), format("%f", d.Bids[i].Amount)});
      }
      
      LogStatus("`" + tbl.dump() + "`");
      // C++ does not support "return json" to display the table, and you can create the live trading to display the table of the status bar
  }
  

• Menggambar perbezaan antara tempoh

  // Draw cross-period spreads
  var chart = { 
      __isStock: true,    
      title : { text : 'spread analysis chart'},                     
      xAxis: { type: 'datetime'},                 
      yAxis : {                                        
          title: {text: 'spread'},                   
          opposite: false                   
      },
      series : [                    
          {name : "diff", data : []}
      ]
  }  
  
  function main() {
      exchange.SetContractType('quarter')
      var recordsA = exchange.GetRecords(PERIOD_M5)
      exchange.SetContractType('this_week')
      var recordsB = exchange.GetRecords(PERIOD_M5)
      
      for(var i = 0; i < Math.min(recordsA.length, recordsB.length); i++){
          var diff = recordsA[recordsA.length - Math.min(recordsA.length, recordsB.length) + i].Close - recordsB[recordsB.length - Math.min(recordsA.length, recordsB.length) + i].Close
          chart.series[0].data.push([recordsA[recordsA.length - Math.min(recordsA.length, recordsB.length) + i].Time, diff])
      }
      return chart
  }
  

  chart = {
      "__isStock": True,
      "title": {"text": "spread analysis chart"},
      "xAxis": {"type": "datetime"},
      "yAxis": {
          "title": {"text": "spread"}, 
          "opposite": False
      }, 
      "series": [
          {"name": "diff", "data": []}
      ]
  }  
  
  def main():
      exchange.SetContractType("quarter")
      recordsA = exchange.GetRecords(PERIOD_M5)
      exchange.SetContractType("this_week")
      recordsB = exchange.GetRecords(PERIOD_M5)  
  
      for i in range(min(len(recordsA), len(recordsB))):
          diff = recordsA[len(recordsA) - min(len(recordsA), len(recordsB)) + i].Close - recordsB[len(recordsB) - min(len(recordsA), len(recordsB)) + i].Close
          chart["series"][0]["data"].append([recordsA[len(recordsA) - min(len(recordsA), len(recordsB)) + i]["Time"], diff])
      return chart
  

  // C++ does not support "return json" structure drawing
