   int          ma_period,        // MA averaging period
   int          ma_method,        // MA averaging method
   int          ma_shift,         // moving average shift
   int          applied_price,    // applied price
   double       deviation,        // deviation (in percents)
   int          mode,             // line index
   int          shift             // shift
   );
