QUESTION
I have been stock on this error on my project when I add "proxy": "http://localhost:6000"
in my package.json.
This is the error response after yarn start.
Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.
- options.allowedHosts[0] should be a non-empty string. error Command failed with exit code 1. info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
But everything is fine when I remove the "proxy": "http://localhost:6000".
This is on my package.json:

Answered 2021-Dec-19 at 16:06Here is a workaround. Delete "proxy": "http://localhost:6000". Install package http-proxy-middleware with command npm install http-proxy-middleware --save. Create a file setupProxy.js inside your src folder. Add these lines inside:
QUESTION
Good afternoon,
When I try to update part of a JSON Object, using ON DUPLICATE KEY UPDATE, how do you update a specific value with a key?
The code executes successfully but all values are updated when I just want the stock to change on update.
Any help would be welcomed, I am not convinced, I understand the MySQL JSON Path syntax, or perhaps JSON_SET cannot achieve my goal?
...ANSWER
Answered 2021-Nov-29 at 10:05If I understand correctly, you just need to use the VALUES function inside INSERT ... ON DUPLICATE KEY UPDATE statement which gives you access to the value being inserted:
QUESTION
i am currently working with plotly i have a function called plotChart that takes a dataframe as input and plots a candlestick chart. I am trying to figure out a way to pass a list of dataframes to the function plotChart and use a plotly dropdown menu to show the options on the input list by the stock name. The drop down menu will have the list of dataframe and when an option is clicked on it will update the figure in plotly is there away to do this. below is the code i have to plot a single dataframe
...ANSWER
Answered 2022-Feb-18 at 07:18I adapted an example from the plotly community to your example and created the code. The point of creation is to create the data for each subplot and then switch between them by means of buttons. The sample data is created using representative companies of US stocks. one issue is that the title is set but not displayed. We are currently investigating this issue.

QUESTION
I am working on certain stock-related projects where I have had a task to scrape all data on a daily basis for the last 5 years. i.e from 2016 to date. I particularly thought of using selenium because I can use crawler and bot to scrape the data based on the date. So I used the use of button click with selenium and now I want the same data that is displayed by the selenium browser to be fed by scrappy. This is the website I am working on right now. I have written the following code inside scrappy spider.

Answered 2022-Jan-14 at 09:30The 2 solutions are not very different. Solution #2 fits better to your question, but choose whatever you prefer.
Solution 1 - create a response with the html's body from the driver and scraping it right away (you can also pass it as an argument to a function):
QUESTION
I'm trying to learn rust and have some issues when trying to work with streams of futures. I have the following code
...ANSWER
Answered 2022-Jan-02 at 21:15This almost certainly has nothing to do with async or futures. This is just the normal requirement for collect to provide a type. collect() can create a number of return types and doesn't know what you want. You probably want a Vec like:
QUESTION
As defined here the Hindenburg omen indicator is:
The daily number of new 52-week highs and 52-week lows in a stock market index are greater than a threshold amount (typically 2.2%).
To me it means, we roll daily and look back 52 weeks or 252 business/trading days, then count the number of highs (or lows) and finally compute the return of that or pct_change, which is the ratio of new highs (or lows) they want to monitor e.g., being above 2.2%
...ANSWER
Answered 2021-Dec-21 at 02:21Interesting question! Could I suggest the following code - it runs much faster than the apply solution because it is vectorised, and also lays out the steps a bit more clearly so you can inspect the interim results.
I got a different result to your code - you can compare by also plotting your result on the timeseries at bottom.
QUESTION
I am working with two dataframes:
dfcontains a columnbe/mefor stocks for a 20-year period (on a monthly basis).df2, a subset ofdf(with only certain stocks, only for June) contains the columndecile, created via thepd.qcut()method for every year in the 20-year period based on an altered version ofdf'sbe/me.
Considering the deciles that I created in df2, I wonder if it's possible to rank df's be/me based on df2's decile column. In other words, I wonder if it's possible to assign df's be/me values to the deciles created in df2.
Please see dataframes below for a better understanding of the issue:
...ANSWER
Answered 2021-Dec-16 at 16:35To be clear: you want to know for each be/me value in df which decile it would have fallen into if that value had been in df2? I see two cases:
If
df2covers the whole month of June (as you wrote), I am afraid there is no answer to that question: each day in the month will have decile bins with different edges (since you are doing agroupby('date')ondf2). The samebe/mevalue indfcould belong to different deciles indf2depending on the day in June you consider.If
df2actually covers only one day in June (as your example above seems to indicate:2020-06-30), then you have one well defined set of decile bins.
In case 2), you could do that:

You can use stock like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
