Enumerated types and explanation here
Probably better to use OBJ_TREND which uses two co-ordinates where VLINE uses only one.
well the documentation says Vertical line. Uses time part of first coordinate. This implies there is a 2nd coordinate so I'm not sure if that's true. I've actually tried using OBJ_TREND and that doesn't work either!

sorry you are right OBJ_TREND does work - but isn't it unbelievable that the more obvious one doesn't work!?
Virtical line needs only one value to be drawn - the time - the program requires as parameters two values so the price value is added in but not used.
Trend line requires two co-ordinates, Two end points. Makes sense to a programmer (smile)
sd59: It draws a line but the full height of the chart and at position 1!!!
of course it does, that's what a VLINE is. Use a TLine.
From my code:
void VLine(string name, datetime T0, color clr){ // #define WINDOW_MAIN 0 if (!Show.Objects) return; if (ObjectMove( name, 0, T0, 0 )){} else if (!ObjectCreate( name, OBJ_VLINE, WINDOW_MAIN, T0, 0 )) Alert("ObjectCreate(",name,",VLINE) failed: ", GetLastError() ); if (!ObjectSet(name, OBJPROP_COLOR, clr )) // Allow color change Alert("ObjectSet(", name, ",Color) [2] failed: ", GetLastError() ); if (!ObjectSetText(name, TimeToStr(T0, TIME_MINUTES), 10)) Alert("ObjectSetText(",name,") [4] failed: ", GetLastError()); } void TLine( string name, datetime T0, double P0, datetime T1, double P1, color clr, double V0=INF, double V1=INF, bool ray=false, int iWin=0){ if (!Show.Objects) return; #define WINDOW_MAIN 0 if (ObjectMove( name, 0, T0, P0 )) ObjectMove(name, 1, T1, P1); else if (!ObjectCreate( name, OBJ_TREND, iWin, T0, P0, T1, P1 )) Alert("ObjectCreate(",name,",TREND) failed: ", GetLastError() ); else if (!ObjectSet( name, OBJPROP_RAY, ray )) Alert("ObjectSet(", name, ",Ray) failed: ", GetLastError()); if (!ObjectSet(name, OBJPROP_COLOR, clr )) // Allow color change Alert("ObjectSet(", name, ",Color) [4] failed: ", GetLastError()); if (V0 != INF && V0 != P0) // Non-price indicator overlayed on chart if (MathAbs( (V0 - V1) / MathMax(V0, V1) ) < 0.001) string P0t = StringConcatenate(V0,""); else P0t = StringConcatenate(V0, " to ", V1); else if (iWin != WINDOW_MAIN) if (MathAbs( (P0 - P1) / MathMax(P0, P1) ) < 0.001) P0t = StringConcatenate(P0,""); else P0t = StringConcatenate(P0, " to ", P1); else if (MathAbs(P0 - P1) < Point_2) P0t = PriceToStr(P0); else P0t = PriceToStr(P0) + " to " + PriceToStr(P1); if (!ObjectSetText(name, P0t, 10)) Alert("ObjectSetText(",name,") [1] failed: ", GetLastError()); }
