Help changing indicator from lines to arrow on cross

Hi group; I have this indi that I am stuck with. It displayed lines when direction changed up or down. I am trying to just plot an arrow up & down at the point when direction changes from up to down instead. Can someone fix it for me? I am stuck as to how to finish this. Thanks!

Here is some of the code:

#property copyright "MT4"

#property link ""

#property indicator_chart_window

#property indicator_buffers 2

#property indicator_color1 Blue

#property indicator_color2 Red

extern int period = 50;

extern int method = 3;

extern int price = 0;

double g_ibuf_88[];

double g_ibuf_92[];

double g_ibuf_96[];

double CrossUp[];

double CrossDown[];

extern int Arrow_Distance = 10;

int init() {

IndicatorBuffers(3);

SetIndexBuffer(0, g_ibuf_88);

SetIndexBuffer(1, g_ibuf_92);

SetIndexBuffer(2, g_ibuf_96);

ArraySetAsSeries(g_ibuf_96, TRUE);

//---- indicators

SetIndexStyle(0, DRAW_ARROW, EMPTY);

SetIndexArrow(0, 233);

SetIndexBuffer(0, CrossUp);

SetIndexStyle(1, DRAW_ARROW, EMPTY);

SetIndexArrow(1, 234);

SetIndexBuffer(1, CrossDown);

//----

// SetIndexStyle(0, DRAW_LINE, STYLE_SOLID, 2);

// SetIndexStyle(1, DRAW_LINE, STYLE_SOLID, 2);
