Trailing Stoploss is Invaid Stop

[Vikram J U]

Sir,

I am using Multi-Symbol...

It has one found "Failed Modify this Stoploss (Invalid Stop)" but It has working to modified this Stoploss is too many times .

Please see this attached photo..

//Input
input group "Trailing Start & Step, Stop :- "
input bool TrailingStart_Step_Stop = true;
input int Trail_start = 10;
input int Trail_Step = 5;
input int Trail_stop = 5;


// Trailing Point
double Trail_start_point;
double Trail_Step_point;
double Trail_stop_point;

int OnInit()
  {
//Digits
   int digits = 1;
   if(Digits() == 3 || Digits() == 5)
     {
      digits = 10;
      point = Point() * digits;
     }
   else

         point = Point() * 1;
        }


//Trailing Start,Step,Stop
   Trail_start_point = Trail_start * point;
