QUESTION
my code
...ANSWER
Answered 2021-Oct-02 at 06:03The solution can be found in the documentation you linked. The keyword in this case is class.
From the documentation:
classta.volatility.AverageTrueRange (...)...
average_true_range() -> pandas.core.series.Series
So you are currently just creating a class holding parameters for creating your desired output. However, you are not calling the function (average_true_range()) that actually calulates and returns the Seriesyou can add to your DataFrame.
Therefore, change your code as shown below to add the atr series to your DataFrame.
QUESTION
I'm trying to run a Scrapy spider on pages like this:
https://careers.mitre.org/us/en/job/R104514/Chief-Engineer-Technical-Analysis-Department
And I'd like the spider to retrieve the bullet points with qualifications and responsibilities. I can write an xpath expression that gets exactly that, and it works in my browsers:
//*/section/div/ul/li
But when I try to use the Scrapy shell:
response.xpath("//*/section/div/ul/li")
It returns an empty list. Based on copying the response.text and loading it in a browser, it seems like the text is accessible, but I still can't access those bullets.
Any help would be much appreciated!
...ANSWER
Answered 2021-Aug-24 at 00:59Looking at the page you have linked, the list items you are targeting are not actually in the document response itself but later loaded into the DOM by JavaScript.
To access these I'd recommend looking at scrapy's documentation on Selecting dynamically-loaded content. The section that applies here in particuler is the Parsing JavaScript code section.
Following the second example, we can use chompjs (you'll need to first install it with pip) to extract the JavaScript data, unescape the html string, and then load it into scrapy for parsing. e.g.:

QUESTION
I am using the package from here. What I am trying to do is to calculate the Stochastic value for each ticker. I have the following code:
...ANSWER
Answered 2020-Jun-12 at 23:23It seems that the method StochasticOscillator expects time series, with single column. But, when you have built your dataframe from web.DataReader, it gave you as much column as tickers.
So you just have to iterate over the tickers, and append the output time series to a new dataframe :

QUESTION
What I am trying to do is create something that looks like this,
which I have created by using the Octave pcolor and barh functions using 3 subplots with the subplot x axes scaled to look as if the figure were one plot. However, this approach is unsatisfactory as I cannot zoom or pan across it as I would be able to if it were actually one plot.
How can I plot one background figure using pcolor and then add multiple y axes at different points along the x axis to plot the horizontal histograms using barh?
For some background to this question, I am trying to create what is called a Market Profile chart, i.e. see example here or here.
I have also cross posted this question on the Octave mailing list here.
...ANSWER
Answered 2020-May-18 at 17:24I have found a way to do what I want. Instead of using the barh function, one can use the fill function instead.
A minimal, reproducible example given below.
