Digital currency: the function of currency pairs

• Exchange currency pairs when running

All digital currency exchanges except for ETH (as ETH is a separate API address for tokens)货币对I'm not sure what to do. Please note: Update the most recent administrator protocols

• Examples

  // 切换Bter交易对为LTC_BTC, 切换后所有交易函数都受影响
  exchange.IO("currency", "LTC_BTC");
  
  // 切换P网交易对为BTC_XRP, 切换后所有交易函数都受影响
  exchange.IO("currency", "BTC_XRP");
  
  // 切换 OKCoin 交易对为 LTC ，切换后所有交易函数都受影响
  exchange.IO("currency", "LTC");

• We use the interactive functionality to test, and during the program run we switch the currency from BTC to LTC.

  Note: All transaction functions are affected after the switch

var preRecordTime = 0;
function main() {
    LogReset(1);
    while (true) {
        var records = exchange.GetRecords();

        // 交互
        var cmd = GetCommand(); // 调用API  获取界面交互控件的消息。 
        if (cmd) { // 判断是否有消息
            var js = cmd.split(':', 2)[1]; // 分割 返回的消息 字符串， 限制返回2个， 把索引为1的 元素 赋值给 名为js 的变量 
            Log("执行调试代码:", js); // 输出 执行的代码
            try { // 异常检测
                eval(js); // 执行 eval函数， 该函数执行传入的参数（代码）。
            } catch (e) { // 抛出异常
                Log("Exception", e); // 输出错误信息
            }
        }

        if (records && records.length > 2) {
            if(records[records.length - 1].Time !== preRecordTime){
                Log("币种：", exchange.GetCurrency(), "倒数第一bar:", records[records.length - 1], "倒数第二bar:", records[records.length - 2]);
                preRecordTime = records[records.length - 1].Time;
            }
        }
        LogStatus("时间：", _D(), "币种：", exchange.GetCurrency(), "records:", (records == null || (records && records.length == 0)) ? "--" : records[records.length - 1]);
        
        Sleep(500)
    }
}

• The first step is to add an interactive control, like this:

  

• The new robot, running.

  

• Open the interactive controller, enter the codeexchange.IO("currency", "LTC");Call the function to switch the currency pair to LTC.

  

• Identify the executable code

  

• As you can see, the transaction data has changed to LTC.
