-------------------------------------------

void MarkV( string name, double price, int bar, int wingdng, color colr)
{
// wingdings: 228/230 buy/sell arrows,
// colors; buy/sell Aqua/Maroon
name=name+bar;
ObjectCreate(name ,OBJ_ARROW,0,Time[bar],price);
ObjectSet(name,OBJPROP_ARROWCODE,wingdng);
ObjectSet(name,OBJPROP_COLOR,colr);
}

// ex. MarkV("mtm5", Low[1], 0, 190, Black);

------------------------------

void DrawLine(string name, datetime time1, double val1, datetime time2, double val2, color col, int width, int style, bool ray)
{
//Plots a line with the given parameters
ObjectDelete(name);
ObjectCreate(name, OBJ_TREND, 0, time1, val1, time2, val2);
ObjectSet(name, OBJPROP_COLOR, col);
ObjectSet(name, OBJPROP_WIDTH, width);
ObjectSet(name, OBJPROP_STYLE, style);
ObjectSet(name, OBJPROP_RAY, ray);
}//End void DrawLine()

// ex. DrawLine("ttnl "+Bars, Time[3], High[3], Time[2],High[3]+2*spread, Brown, 2, STYLE_SOLID, false);
// ex2. DrawLine(" Aline ", Time[startA],Avalue, Time[0],Avalue, Brown, 3, STYLE_SOLID, false);

jjasper7 wrote:george, that display problem is still giving me grief. it would be very helpful if i could find a breakpoint debugger to help. do you know of such a program to help find errors?
