Great! Thank you very much.
Although, it doesn't seem to draw any vlines... odd. Maybe because I am in strategy tester.
its working on my terminal
You may use this little puppy... it draws a Vline at given time with given color.
I use it as a very handy debugging & visualization tool.
//----------------------------------------------------------- void DrawVline (color Color, datetime time) {//Use: DrawVline(Yellow, Time[i]); static int cntr; static double PrevVlineTime; if (time == PrevVlineTime) return(0);//Still on same bar ObjectCreate( "UpLine"+cntr, OBJ_VLINE, 0, time, 0); ObjectSet("UpLine"+cntr, OBJPROP_COLOR, Color); ObjectSet("UpLine"+cntr, OBJPROP_BACK,true); cntr++; PrevVlineTime = time;//Store bar time of last drawn line return(0); } //-----------------------------------------------------------

Object names must be unique. When a new bar forms, you will be (potentially) reusing names. Time is unique. -
ma1=iMA(NULL,0,7,0,MODE_SMMA,PRICE_MEDIAN,i);
Never any reason to use the SMMA(L) it's equivalent to the EMA(2L-1).

Thanks, it is true!
Thanks for any help on this. I just want to draw an VLine (vertical line) at each ma cross on my charts. How can I access back-data for an iMA? (I can code it going forward, that's simple, but going backwards?)
Thank you very much for any help!
