Thinkscript that draws a line at the stock or ETF opening Price.


New member
Is it possible to write a script that will place a line each day at the stocks or ETF's opening price of each day? I want to be able to look at a chart of the Stock or ETF and see of it is trading above or below the opening price of the opening bar.
You can write a lotta lines to show up based on previous days, weeks, or even months range.

plot pDayOpen = open(;
plot pWkOpen = open(period=aggregationperiod.week);
plot pMoOpen = open(period=aggregationperiod.month);

Shake it up a little so you can adapt for intraday timeframes easliy. In this code, the previous days open is plotted on the current days price action:

input ShortTF =;
input MedTF  = aggregationperiod.week;
input LongTF = aggregationperiod.month;

plot ShortO = open(period=shortTF)[1];
plot MedO  = open(period=MedTF)[1];
plot LongO = open(period=LongTF)[1];

In a number of scripts I've written, I add a variable called "lookback". By doing this, a user input is added allowing you to shift how many days back you want the code to draw. 0 = current day, 1 = previous day. For it to be used, just replace the [1] on each line with [lookback] .

input lookback = 1;
