hi hellkas,
1- Arrows in the chart;
Use this code to draw an arrow (color=Gold, Width=1) in the main window.
PHP Code:
ObjectCreate("my arrow", OBJ_ARROW, 0, Time[0], High[0]+Point*10);
ObjectSet("my arrow", OBJPROP_ARROWCODE, 1);
ObjectSet("my arrow", OBJPROP_COLOR , Gold);
ObjectSet("my arrow", OBJPROP_WIDTH , 1);
ObjectsRedraw();
2) Alert when cross;
This is my Alerts demo (working when 8EMA crosses 13EMA and telles you the direction):
PHP Code:

#property copyright "Coders Guru"

#property indicator_chart_window
#property indicator_buffers 2
#property indicator_color1 Red
#property indicator_color2 Blue
//---- buffers
double ExtMapBuffer1[];
double ExtMapBuffer2[];
//+------------------------------------------------------------------+
//| Custom indicator initialization function |
//+------------------------------------------------------------------+
int init()
{
//---- indicators
SetIndexStyle(0,DRAW_LINE);
SetIndexBuffer(0,ExtMapBuffer1);
SetIndexStyle(1,DRAW_LINE);
SetIndexBuffer(1,ExtMapBuffer2);
//----
return(0);
}
//+------------------------------------------------------------------+
//| Custor indicator deinitialization function |
//+------------------------------------------------------------------+
int deinit()
{
//----

return(0);
}
bool Crossed (double line1 , double line2 ,string& direction)
{
static string last_direction = "";
string current_dirction = "";
if(line1>line2)current_dirction = "up";
if(line1<=line2)current_dirction = "down";
if(current_dirction != last_direction)
{
Alert("CRROSED: Line1 is (" + current_dirction + ") Line2 now");
last_direction = current_dirction;
direction=current_dirction;
return (true);
}
else
{
direction=current_dirction;
return (false);
}
}
int start()
{
int counted_bars=IndicatorCounted();
//---- check for possible errors
if (counted_bars<0) return(-1);
//---- last counted bar will be recounted
if (counted_bars>0) counted_bars--;
int pos=Bars-counted_bars;
while(pos>=0)
{
ExtMapBuffer1[pos] = iMA(NULL,0,8,0,MODE_EMA,PRICE_CLOSE,pos);
ExtMapBuffer2[pos] = iMA(NULL,0,13,0,MODE_EMA,PRICE_CLOSE,0);
pos--;
}
string direction;
Print(Crossed (ExtMapBuffer1[0],ExtMapBuffer2[0],direction));
//----
return(0);
}
//+------------------------------------------------------------------+
3) Comment in the left corner;
This line of code will print a comment on the top left corner of the main window:
PHP Code:
Comment("Hi! I'm here on the main chart windows!");
I hope I helped!
