I would like some tips about how to draw 2 lines (at High and Low) of a specific bar after a specific condition has been meet.

eg. if the current bar, after close (that means bar[1] because the new bar[0] is already started and is forming, is an inside bar of the previous bar (in that case bar[2]), I would like to draw 2 lines at High and Low of bar[2].

Many thanks in advance

Hi skipper and welcome,

Here is an idea :

string Inside="false";
if(conditions)Inside="true";

for(int i=0;i<2;i+=2){
if(Inside="true"){
ObjectDelete("recth"+i);
ObjectCreate("recth"+i,OBJ_HLINE,0,0,High[1]);
ObjectSet("recth"+i,OBJPROP_COLOR,Red);
ObjectSet("recth"+i,OBJPROP_WIDTH,1);
ObjectSet("recth"+i,OBJPROP_RAY,False);}
if(conditions to delete the lines){ObjectDelete("recth"+i);}
}

for(int j=0;j<2;j+=2){
if(Inside="true"){
ObjectDelete("rectl"+j);
ObjectCreate("rectl"+j,OBJ_HLINE,0,0,Low[1]);
ObjectSet("rectl"+j,OBJPROP_COLOR,Red);
ObjectSet("rectl"+j,OBJPROP_WIDTH,1);
ObjectSet("rectl"+j,OBJPROP_RAY,False);}
if(conditions to delete the lines){ObjectDelete("rectl"+j);}
}
