hi, is it possible to draw a line to 2 pts on the same bar? eg draw a line from open to close price on the same bar thanks

bool ObjectCreate( string name, int type, int window, datetime time1, double price1, datetime time2=0, double price2=0, datetime time3=0, double price3=0)

You enter the price & time of the first coordinate. Followed by the price and time of the second coordinate.

is it possible to do it without objects? what about drawing it in an indicator, using SetIndexStyle or equivalent?

[Ubzen]

Yes, that should be possible. Here's a good article for start.

thanks, next question: is it possible to draw a line between 2 indicator buffers? eg from buff1[] to buff2[]

Yes, by using objects.

void TLine( string name, datetime T0, double P0, datetime T1, double P1
          , color clr, bool ray=false ){                #define WINDOW_MAIN 0
    if (!Show.Objects)  return;
    /**/ if(ObjectMove( name, 0, T0, P0 ))      ObjectMove(name, 1, T1, P1);
    else if(!ObjectCreate( name, OBJ_TREND, WINDOW_MAIN, 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) [2] failed: ", GetLastError());
    string  P0t = PriceToStr(P0);           if (MathAbs(P0 - P1) >= Point)
            P0t = StringConcatenate(P0t, " to ", PriceToStr(P1));
    if (!ObjectSetText(name, P0t, 10))
        Alert("ObjectSetText(",name,") [2] failed: ", GetLastError());
}
void HLine(string name, double P0, color clr){  //      #define WINDOW_MAIN 0
    if (!Show.Objects)  return;
    /**/ if (ObjectMove( name, 0, Time[0], P0 )){}
    else if(!ObjectCreate( name, OBJ_HLINE, WINDOW_MAIN, Time[0], P0 ))
        Alert("ObjectCreate(",name,",HLINE) failed: ", GetLastError() );
    if (!ObjectSet(name, OBJPROP_COLOR, clr )) // Allow color change
        Alert("ObjectSet(", name, ",Color) [1] failed: ", GetLastError() );
    if (!ObjectSetText(name, PriceToStr(P0), 10))
        Alert("ObjectSetText(",name,") [1] failed: ", GetLastError());
}
