How can draw an arrow in the next bar with this code

[monarcatrades]

Hi i need your help, 

I need to draw an arrow on the next bar and not on the current bar which is drawn by this indicator. What could I modify?

Many Thanks.

#property indicator_chart_window

// The number of buffers for calculation, up to 8
#property indicator_buffers 2

// The color for displaying arrows
#property indicator_color1 Green       // Long signal
#property indicator_color2 Maroon         // Short signal

// Width of the arrows
#property indicator_width1 2  // Long signal arrow
#property indicator_width2 2  // Short signal arrow

extern bool UseFullCandleSize = false;
extern int NumberOfCandles = 3;
extern int ArrowDistance = 1;

// Buffers for the calculations
double Up_Arrow_Buffer[];    // Long buffer for display
double Down_Arrow_Buffer[];   // Short buffer for display
int PipFactor = 1;

3. Your code	bool isDownCandle(int index) {    if (Close[index] < Open[index])    {       return (true);    }    return (false); }
   Simplified	bool isDownCandle(int index) {    return Close[index] < Open[index]; }
