    //Trend emas 
   int WeeklyTrend = iMA(_Symbol,PERIOD_W1,8,0,MODE_EMA,PRICE_CLOSE);
   int DailyTrend = iMA(_Symbol,PERIOD_D1,8,0,MODE_EMA,PRICE_CLOSE);
   
   //emas 
   int MAONE = iMA(_Symbol,_Period,9,0,MODE_SMA,PRICE_CLOSE);
   int TWOEMA = iMA(_Symbol,_Period,200,0,MODE_EMA,PRICE_CLOSE);
   
   ArraySetAsSeries(WeeklyTrendArray,true);
   ArraySetAsSeries(DailyTrendArray,true);
   ArraySetAsSeries(MAONEARRAY,true);
   ArraySetAsSeries(EMATWOARRAY,true);

   double Balance= AccountInfoDouble(ACCOUNT_BALANCE);
   double Equity = AccountInfoDouble(ACCOUNT_EQUITY);
   

   
   //copybuffer for all 
  CopyBuffer(WeeklyTrend,0,0,3,WeeklyTrendArray);
