STOCHMI

I create A STOCH MI indicator:  

and i ceate a robot  with the data from that indicator for trigger: 

-the graph show on M30 2 ligne that pass close to each other but not cross over .... 

 -but i reseave data from the indicator that they cross over :

What i can do to reseave only the onbar data from the indicator:

              Result[index] = _smi[index] * 100;
                MaResult[index] = _maSmi.Result[index] * 100;

   if (MaResult.Last(1) >= Result.Last(1) && MaResult.LastValue <= Result.LastValue )

            {
                Print("checkbuy{0} > {1} AND {2} < {3}", MaResult.Last(1), Result.Last(1), MaResult.LastValue, Result.LastValue);
           }

            if (MaResult.Last(1) <= Result.Last(1) && MaResult.LastValue >= Result.LastValue )
            {
               Print("checksell {0} < {1} AND {2} > {3}", MaResult.Last(1), Result.Last(1), MaResult.LastValue, Result.LastValue);
            }
