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

[Tomk02]

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.

They already have one. Go to think script studies and look for DailyOpen. It gives you past and present open by setting it to yes or no.

You can write a lotta lines to show up based on previous days, weeks, or even months range.

plot pDayOpen = open(period=aggregationperiod.day);
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 = aggregationperiod.day;
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;
