"M1 "而不是 "PERIOD_M1"

void OnStart()
  {
   ENUM_TIMEFRAMES timeframe = Period();
   string result = GetTimeframeShortName(timeframe);
   Comment(result);
   Print(result);
  }
//+------------------------------------------------------------------+
//| 获取时间范围简称的函数
//+------------------------------------------------------------------+
string GetTimeframeShortName(const ENUM_TIMEFRAMES timeframe)
  {
    switch(timeframe)
      {
        case PERIOD_M1: return "M1";
        case PERIOD_M2: return "M2";
