## Find Oscillators Last Cross

 13118 WHRoeder 2016.04.13 14:35 #   FxTrader_: I would like to ask if there is any existing indicator or any way to find statistic Oscillators previous crossed.Look back bars and check```int find_XX_cross(int iBeg=0){   for(;iBeg < Bars; ++iBeg){      bool wasAbove = xx(..., FAST, iBeg+1) > xx(..., SLOW, iBeg+1);      bool  isAbove = xx(..., FAST, iBeg)   > xx(..., SLOW, iBeg);      bool hasCrossed = isAbove != wasAbove;      if(hasCrossed) return iBeg;   } ///// int Last_Crossed = find_XX_cross(); int Prev_Cross[2]; Prev_Cross[0] = find_XX_cross(Last_Crossed+1); Prev_Cross[1] = find_XX_cross(Prev_Cross[0]+1);```

Please help.```     int find_XX_cross(int iBeg=0)             {      for(iBeg < Bars; ++iBeg)        {         bool wasAbove = xx(iStochastic(NULL,0,15,5,5,MODE_SMA,0,MODE_MAIN,iBeg+1) > xx(iStochastic(NULL,0,15,5,5,MODE_SMA,0,MODE_SIGNAL,iBeg+1)));         bool  isAbove = xx(iStochastic(NULL,0,15,5,5,MODE_SMA,0,MODE_MAIN,iBeg)   > xx(iStochastic(NULL,0,15,5,5,MODE_SMA,0,MODE_SIGNAL,iBeg)));                  bool hasCrossed = isAbove != wasAbove;         if(hasCrossed) return iBeg;        }          /////          int Last_Crossed = find_XX_cross();          int Prev_Cross[2];          Prev_Cross[0]    = find_XX_cross(Last_Crossed+1);          Prev_Cross[1]    = find_XX_cross(Prev_Cross[0]+1);      }```

So I wrote XX():```bool wasAbove = xx(..., FAST, iBeg+1) > xx(..., SLOW, iBeg+1); bool  isAbove = xx(..., FAST, iBeg)   > xx(..., SLOW, iBeg);```You replaced FAST and SLOW, with MAIN and SIGNAL. why didn't you follow through and replace xx() with your oscillator also?bool wasAbove = xx(iStochastic(NULL,0,15,5,5,MODE_SMA,0,MODE_MAIN,iBeg+1) > xx(iStochastic(NULL,0, 15, 5, 5, MODE_SMA, 0, MODE_SIGNAL, iBeg+1))); bool  isAbove = xx(iStochastic(NULL,0,15,5,5,MODE_SMA,0,MODE_MAIN,iBeg)   > xx(iStochastic(NULL,0, 15, 5, 5, MODE_SMA, 0, MODE_SIGNAL, iBeg)));
