Hey Friends,

I have to plot Horizontal line for HIGH on Particular Day, for example, I have to plot horizontal line for OCT 21 2018.s Days HIGH,

I have tried different ways but not getting the results, below is the example

Plot (LastValue(TimeFrameGetPrice("High", inDaily, -45)), "Prev H", colorGreen);

For the above code, I need to increase days (-445 to 446.....) each day, so I am requesting you please provide me the solution for constant.

Thanks you.

Use ValueWhen or LookUp.

dtstr = "2018-10-21 00:00:00";

dt = DateTime();
hh_day = TimeFrameGetPrice("High", inDaily, 0);
hh_dt = ValueWhen(dt == _DT(dtstr), hh_day);

Plot(hh_dt, "Prev H", colorGreen);
Plot( C, "Price", colorDefault, styleBar );

dtstr = "2018-10-21 00:00:00";

hh_day = TimeFrameGetPrice("High", inDaily, 0);
hh_dt = Lookup(hh_day, _DT(dtstr));

Plot(hh_dt, "Prev H", colorGreen);
Plot( C, "Price", colorDefault, styleBar );
