  • 测试代码 (Test code) :

var initAccount = null;
var nowAccount = null;
function main() {
    LogReset(1);
    Log("This is BitMEX test bot");
    Log("Fee:", exchange.GetFee());
    Log("Initial account:", initAccount = _C(exchange.GetAccount));    
    var info = exchange.SetContractType("XBTUSD");   // BitMEX : XBTUSD , OK : this_week
    Log("XBTUSD info:", info);   
    Log("Use GetTicker to get ticker information:", _C(exchange.GetTicker)) 
    Sleep(1000 * 10);   
    // make an order
    exchange.SetDirection("sell");                         // set order direction
    var orderId = exchange.Sell(-1, 1);                    // sell at market price。
    Sleep(6000);
    // log positions
    var positions = null;
    Log(positions = _C(exchange.GetPosition));
    Log("Account before changing leverage:", _C(exchange.GetAccount));
    // change leverage
    Log("Change leverage", _C(exchange.SetMarginLevel, positions[0].MarginLevel * 2));
    Log("Account after changing leverage:", _C(exchange.GetAccount));  
    // test GetOrder 
    if (orderId) {
        Log(_C(exchange.GetOrder, orderId));
    } 
    Sleep(1000 * 10);
    Log(_C(exchange.GetPosition));
    // set direction to close
    exchange.SetDirection("closesell");
    var go_buy = exchange.Go("Buy", -1, 1);
    var orderId2 = go_buy.wait();
    Log(_C(exchange.GetOrder, orderId2));
    Log("Current account:", nowAccount = _C(exchange.GetAccount));
    Log(_C(exchange.GetPosition));
    LogProfit(nowAccount.Stocks - initAccount.Stocks, " initAccount:", initAccount, " nowAccount:", nowAccount);
    Sleep(1000 * 10);
    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("Cancel order, test GetOrders again:", _C(exchange.GetOrders));
}
  • Check your account information at BitMEX.

    img

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

    img

  • Log positions after changing leverage, the leverage has been changed (下市价单后调整杠杆,对比前后持仓信息。)

    img

  • Use Go function to cover your positions at the same time. (调用 Go 函数异步多线程平仓)

      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);
    

    img

  • Let’s try post orders and cancel it.(我们试一下挂单。)

    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));
    

    img

    The pending orders’ information. (获取到的挂单信息)

 [{"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"}]
  • Note (注意):

    • 1、BitMEX only supoort K-line periods of 1m,5m,1h,1d.(BitMEX的K线周期只支持1分钟、5分钟、1小时、1天这些周期。)

      使用最新的托管者,底层可以自动合成K线,一些BITMEX 不支持的K线周期数据也可以合成出来,所以在设置K线周期的时候不再局限于1分钟、5分钟、1小时、1天这些周期,所有周期都可以设置。

      img

    • 2、Test holding long and short positions at the same time.(测试同时持有多头仓位、空头仓位)

      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));
      

      img

    • 3、The leverage can be changed while holding position.(持仓后杠杆可调。)

    • 4、Support exchange.IO function for more API. (支持exchange.IO函数)

      img

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