Good evening to everyone, I'm desperate. I need to take the color of the candle (heikin ashi), how can I do?
Thank you in advance
 
You should encapsulate your iCustom calls to make your code self-documenting.

#define  PRICE double            // A PRICE
//+------------------------------------------------------------------+
//| Heiken Ashi iCustom function                                     |
//+------------------------------------------------------------------+
enum HAbuffer{ HA_LOW_HIGH, HA_HIGH_LOW, HA_OPEN, HA_CLOSE, HA_BOTTOM, HA_TOP };
PRICE    Heiken_Ashi(HAbuffer buf, INDEX iBar){
   return Heiken_Ashi(_Symbol, ENUM_TIMEFRAMES(_Period), buf, iBar);
}
PRICE    Heiken_Ashi(ENUM_TIMEFRAMES tf, HAbuffer buf, INDEX iBar){
   return Heiken_Ashi(_Symbol, tf, buf, iBar);
}
PRICE    Heiken_Ashi(SYMBOL sym, ENUM_TIMEFRAMES tf, HAbuffer buf, INDEX iBar){
   #define  HA    "Heiken Ashi"
   if(buf < HA_BOTTOM)  return iCustom(sym, tf, HA,
                                       // All four parameters are just colors
                                       buf, iBar);
   PRICE    lh = iCustom(sym, tf, HA, HA_LOW_HIGH, iBar);
   PRICE    hl = iCustom(sym, tf, HA, HA_HIGH_LOW, iBar);
   return HA_BOTTOM == buf ? MathMin(lh, hl) : MathMax(lh, hl);
}

PRICE haOpen  = Heiken_Ashi(HA_OPEN, 1);
PRICE haClose = Heiken_Ashi(HA_CLOSE, 1);
bool  upCandle  = haClose > haOpen;

with this code the color of the candle where it is stored?

 
There is no color. Only up and down candles.

Please don't answer inside the quote.
 
okok thank you very much. so if I want to open an order when after a red candle there is a green candle, I can not do it?
 
There is no red candle or green candle. The colors can be changed to whatever you want. Stop thinking color. Think up or down. You've been answered three times.

HA close > HA open -> "green"

HA close < HA open -> "red"

 
Same as #1 but made a class: 
//+------------------------------------------------------------------+
//| Heiken Ashi class                                                |
//+------------------------------------------------------------------+
class HeikenAshi{
 public:
               HeikenAshi(void)                                         //[Ctor]
                            : mTF(ENUM_TIMEFRAMES(_Period)), mSymbol(_Symbol){}
               HeikenAshi(ENUM_TIMEFRAMES aTF)                          // Ctor
                            : mTF(aTF),                      mSymbol(_Symbol){}
               HeikenAshi(SYMBOL aSymbol, ENUM_TIMEFRAMES aTF)          // Ctor
                            : mTF(aTF),                      mSymbol(aSymbol){}
 public:                                                             // Methods
enum HAbuffer{ HA_LOW_HIGH, HA_HIGH_LOW, HA_OPEN, HA_CLOSE, HA_BOTTOM, HA_TOP };
   PRICE       get(HAbuffer aBuffer, INDEX iBar){
      static const string  ha = "Heiken Ashi";
      if(aBuffer < HA_BOTTOM)  return iCustom(mSymbol, mTF, ha,
                                          // All four parameters are just colors
                                          aBuffer, iBar);
      PRICE    lh = iCustom(mSymbol, mTF, ha, HA_LOW_HIGH, iBar);
      PRICE    hl = iCustom(mSymbol, mTF, ha, HA_HIGH_LOW, iBar);
      return HA_BOTTOM == aBuffer ? MathMin(lh, hl) : MathMax(lh, hl);
   }
 private:                                                            // Data
   SYMBOL            mSymbol;
   ENUM_TIMEFRAMES   mTF;
}; // class HeikenAshi
  
static HeikenAshi sHA; // Or globally declared
double haOpen = sHA.get(HA_OPEN, iBar);
  
bool isUp(INDEX iBar){
      PRICE    lh = iCustom(mSymbol, mTF, ha, HA_LOW_HIGH, iBar);
      PRICE    hl = iCustom(mSymbol, mTF, ha, HA_HIGH_LOW, iBar);
      return lh < hl;
}
