• Check your account information at BitMEX.

  

  Log the information by bot, which is the same with that on BitMEX.

  

• Log positions after changing leverage, the leverage has been changed (Ajustar el apalancamiento después de la orden de precio de mercado, comparar la información de la posición anterior y posterior <unk>)

  

• Use Go function to cover your positions at the same time. (Invoque la función Go para cubrir sus posiciones al mismo tiempo)

  
              
              
              
    exchange.SetDirection("closesell");
    var go_buy = exchange.Go("Buy", -1, 1);
    var orderId2 = go_buy.wait();
    Log(_C(exchange.GetOrder, orderId2));
    Log("当前账户：", nowAccount = _C(exchange.GetAccount));
    Log(_C(exchange.GetPosition));
    LogProfit(nowAccount.Stocks - initAccount.Stocks, " initAccount:", initAccount, " nowAccount:", nowAccount);
  

  

• Let's try to post orders and cancel it. (Vamos a intentar poner órdenes y cancelarlo)

  
              
              
              
  var ticker = _C(exchange.GetTicker);
  exchange.SetDirection("buy");
  exchange.Buy(ticker.Last - 50, 1);
  exchange.SetDirection("sell");
  exchange.Sell(ticker.Last + 50, 1);  
  // GetOrders
  Log("Test GetOrders:", _C(exchange.GetOrders));
  var e = exchange;
  while (true) {
      var orders = _C(e.GetOrders);
      if (orders.length === 0) {
          break;
      }
      Sleep(500);
      for (var j = 0; j < orders.length; j++) {
          e.CancelOrder(orders[j].Id);
          if (j < (orders.length - 1)) {
              Sleep(500);
          }
      }
  }
  Log("orders have been canceled. Now check orders again, order array is empty. GetOrders:", _C(exchange.GetOrders));
  

  

  La información de las órdenes pendientes.

            
            
            
 [{"Id":4,"Amount":1,"Price":1679.6,"DealAmount":0,"AvgPrice":0,"Status":0,"Type":1,"ContractType":"XBTUSD"},
 {"Id":3,"Amount":1,"Price":1579.6,"DealAmount":0,"AvgPrice":0,"Status":0,"Type":0,"ContractType":"XBTUSD"}]

• Nota: No se puede hacer esto.

  • 1 , BitMEX sólo supoort K-line periods of 1m, 5m, 1h, 1d.

    Con los últimos hosts, la base puede sintetizar automáticamente K-line, y algunos datos de K-line que BITMEX no soporta también pueden sintetizarse, por lo que la configuración de K-line no se limita a1分钟、5分钟、1小时、1天Estos ciclos, todos los ciclos se pueden configurar.

    

  • 2 Test holding long and short positions at the same time. (Posiciones largas y cortas al mismo tiempo)

    
                
                
                
    LogReset(1);
    var info = exchange.SetContractType("XBTUSD");
    exchange.SetDirection("sell");
    var orderId = exchange.Sell(-1, 1);
    Log(_C(exchange.GetPosition));
    Sleep(1000*6);
    exchange.SetDirection("buy");
    var orderId2 = exchange.Buy(-1, 1);
    Log(_C(exchange.GetPosition));
    exchange.SetDirection("closesell");
    var orderId3 = exchange.Buy(-1, 1);
    Log(_C(exchange.GetPosition));
    

    

  • 3. El apalancamiento puede ser cambiado mientras se mantiene la posición.

  • 4 Soporte para la función exchange.IO para más API.

    

    
                
                
                
    // exchange.IO example
    exchange.SetContractType("XBTUSD");
    Log(exchange.IO("api", "POST", "position/leverage", "symbol=XBTUSD&leverage=4"));
    Log(exchange.IO("api", "GET", "user"));
