How can I resolve "Not all control paths return a value" error for integer
int ArrowedCandleIndex () { for (int i=0; i<NumBars; i++) { double dnArrow = iCustom(Symbol(),Period(),ARROWS_SIGNAL_NAME,ARROWS_SIGNAL_BUFFER_DN,i); double upArrow = iCustom(Symbol(),Period(),ARROWS_SIGNAL_NAME,ARROWS_SIGNAL_BUFFER_UP,i); if ((dnArrow!=EMPTY_VALUE) && (DoubleToStr(dnArrow,Digits()) != "0.00000")) { currentArrowedCandleIndex = NumBars; break; //return currentArrowedCandleIndex; } if ((upArrow!=EMPTY_VALUE) && (DoubleToStr(upArrow,Digits()) != "0.00000")) { currentArrowedCandleIndex = NumBars; break; //return currentArrowedCandleIndex; } } return (currentArrowedCandleIndex); }
int ArrowedCandleIndex () { for (int i=0; i<NumBars; i++) { double dnArrow = iCustom(Symbol(),Period(),ARROWS_SIGNAL_NAME,ARROWS_SIGNAL_BUFFER_DN,i); double upArrow = iCustom(Symbol(),Period(),ARROWS_SIGNAL_NAME,ARROWS_SIGNAL_BUFFER_UP,i); if ((dnArrow!=EMPTY_VALUE) && (DoubleToStr(dnArrow,Digits()) != "0.00000")) { currentArrowedCandleIndex = NumBars; return currentArrowedCandleIndex; } if ((upArrow!=EMPTY_VALUE) && (DoubleToStr(upArrow,Digits()) != "0.00000")) { currentArrowedCandleIndex = NumBars; return currentArrowedCandleIndex; } } return(-1); }
return -1 or something suitable if none of the conditions are met.
