Plot Previous Day Close in ThinkorSwim

ThinkScript wizards, I need your help:

So I checked both the code provided at the beginning of this page and the code from Matt Diamond I listed in my previous comment, and they are both very slightly off from the actual previous day close (<1%). If you go to style>settings>price axis>"show price as percentage" and then in your chart if you right click the last bar of the previous day and click "Set Bar as 0%" then that creates a line at the close of the previous day. The indicator created with thinkscript is usually off from that by 0.2-0.8%. I get that's close but is there anyway to make this exactly accurate?

(!) The other thing I would like to figure out is for my 0% level to automatically adjust to the Previous Day Close indicator. I could manually set it, but I would have to do that with EVERY chart I view and that is quite a hassle. Doing this allows me to see how much the stock has changed in percent from the previous day's close on the y axis.

(note you can only set the 0% level if your price axis is set to view as percentages).

Any help here would be greatly appreciated!!

Good morning,

I have previous day close, high and low code but it labels al days. I would need help in displaying only last two days high close and low levels. Can anyone help. Thanks and appreciated.

#Study:Common Level
#by thetrader.top
declare hide_on_daily;
declare once_per_bar;

input timeFrame = {default DAY, WEEK, MONTH};

plot high = If(GetAggregationPeriod() <= AggregationPeriod.FIFTEEN_MIN, high(period = timeFrame)[1], Double.NaN);
plot Low = If(GetAggregationPeriod() <= AggregationPeriod.FIFTEEN_MIN, low(period = timeFrame)[1], Double.NaN);
plot Close = If(GetAggregationPeriod() <= AggregationPeriod.FIFTEEN_MIN, close(period = timeFrame)[1], Double.NaN);

high.SetDefaultColor (Color.GREEN);
high.SetPaintingStrategy(PaintingStrategy.DASHES);
Low.SetDefaultColor(Color.RED);
Low.SetPaintingStrategy(PaintingStrategy.DASHES);
Close.SetDefaultColor (Color.GRAY);
Close.SetPaintingStrategy(PaintingStrategy.DASHES);
 
A thinkscript code to help you plot previous close to your ThinkorSwim chart. The previous day's close level is important to determine intraday directional bias.

Code:
# Previous Day Closing Price (PCL)
input aggregationPeriod = AggregationPeriod.DAY;
def close = close(period = aggregationPeriod)[1];
plot previous_close = close;
Is there a way to only show the previous day close line for only the current day.

as the previous post was asking. i too am wondering how to set the previous day close for RTH, not ETH. is that possible?

This will plot the last RTH close from the previous day
Code:
# Previous Day Closing Price (PCL)
input showtodayonly = yes;
input aggregationPeriod = AggregationPeriod.DAY;
def pc = close(period = aggregationPeriod)[1];
plot previous_close = if showtodayonly and GetDay() != GetLastDay() then Double.NaN else pc;
previous_close.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
 
This will plot the last RTH close from the previous day
that is not working for me. im still getting 5pm EST closing price on /ES (2 hours after closing time), not 3pm EST (RTH closing time). this only works if i have afterhours turned off, which i dont want to do. any suggesting?

I have added some code that will allow you to choose the end time for the previous day.

With the displace set to 0, it will match the close of the bar at the input end. This matches the RTH close as displayed at a Daily chart setting, which does not include afterhours.

With a displace set to 1, it will match last bar's close of the intraday chart, set without afterhours, using the close of the bar prior to input end. This generally does not match the close of RTH as disclosed by close of the Daily bar,

The image shows the 2 Methods in the upperpane.
The middle pane is the intraday chart's close of the previous day.
The lower pane is the Daily chart's previous day's close, which is generally referred to as the RTHrs close, and the close of the middle pane's close with afterhours turned off.

This allows you to choose the code for whatever you feel most comfortable using.

#Method1 - Previous Day Closing Price (PCL)
input display_method1 = yes;
input showtodayonly = yes;
input aggregationPeriod = AggregationPeriod.DAY;

plot previous_close = if showtodayonly and GetDay() != GetLastDay() then Double.NaN else pc;
previous_close.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
previous_close.SetLineWeight(2);
previous_close.SetHiding(!display_method1);

#Method2
input display_method2 = yes;
input end = 1600;
input displace = 1;
def yesterday  = GetDay() == GetLastDay() - 1;
def pclose     = if yesterday and SecondsFromTime(end) == 0 then close[displace] else pclose[1];
def pcbar      = if yesterday and SecondsFromTime(end) == 0 then BarNumber() else pcbar[1];
plot prevclose = if BarNumber() < HighestAll(pcbar) then Double.NaN else pclose;
prevclose.SetStyle(Curve.LONG_DASH);

for some reason, i cant seem to get it to plot it. nothing is showing up on my chart.

With yesterday being a holiday, it disclosed that the script needed to be more complex than that above. So this should hopefully now work if there are holidays or with or without afterhours selected to display on your chart.

Good Day All,

Can someone please modify this code so that specific times can be used for close and or open times and have the option to see history, these additional features would be greatly appreciated.

Thank You !!!
Dorian
