Challenge #69: Web Stock Data

MattD — Tue, 13 Sep 2022 19:13:53 GMT

The solution to last week's challenge is HERE.

Today’s challenge is for all our investors out there! Say you wanted to perform your own unique analyses on a stock, or at least have its trends handy for notification if it was hitting an established threshold of yours. How would you obtain this data?

~~For our challenge, we’ll be using Yahoo Finance! Use the URL below to gather useable (parsed; tabulated format) stock data on AYX (Alteryx!):~~

~~http://ichart.finance.yahoo.com/table.csv?s=AYX~~

~~As of May 2017 - the Yahoo API has closed its service. Instead please use the following URL to get historical data:~~
~~https://www.google.com/finance/historical?output=csv&q=AYX~~
*Due to differences in the API services - there will be no field in the resulting response for "Adj Close"

As of December 2017, the previously used URL produces an error. We've updated this Challenge to point to a new link to download a dataset on attributes of mushrooms. The Start File and Solution have been updated to reflect this change. Happy Challenging!

I went with download tool followed by some text to columns (\n to get rows and , to get columns), followed by dynamic rename to get the column headings. The auto-field gets converts the strings to doubles, and the filter gets the data through 4/28 to match the sample output

Learn some new things thanks to this one!

Only need two tools:
- Download URL to a Temporary File
- Dynamic Input configured to read in a comma separated CSV file, changing full path based on DownloadTempFile

I took it a little further to practice with iterative macros and provided a 50 day moving average and 52 week high and low for each day. Volume is a bit skewed since the first day of trading was much larger than normal, but that will auto correct once there are more than 50 days in the data set.

@Joe_Mako- Nice solution. Took me a bit to figure out the configuration of the second tool, but I got it to work.

My solution - just for kicks, I went a bit of a different route and created an app.

I figured if you had this data and you were looking for certain criteria (such as Adj Close price changed by more than +/- 5% from the prior day, or if it reached a price greater than or less than a certain value), you would want to know. So I added a Daily Change % calculation and then some app parameters. Set it up to just look at "yesterday's" results (i.e. last Friday if today is Monday, otherwise previous day). This would be easy enough to add another prompt asking for the stock symbol, which could then update the text input accordingly and get you results for any stock...

@NicoleJohnson,

Ok, go the extra mile. Try the yahoo finance API and get some real data! I like your approach and encourage you to use an API to deliver value.

Cheers,

Mark

I don't know the answer, but I'd definitely like to know what it is and then learn how to build it in Alteryx Designer for myself. Thanks!

Nice use of the download tool. The output isn't identical as there are now more days in the yahoo data

This was a nice place to start for my first weekly challenge.

A pretty simple solution to a simple challenge, with a couple of charts thrown in as a bonus:

I looked around for some guidance on how to tag my image as a spoiler but couldn't find any - what should I have done?

Re: Challenge #69: Web Stock Data

Natasha — Tue, 09 May 2017 13:41:29 GMT

My solution is similar to others, but used it as an opportunity to try reporting tools.

Re: Challenge #69: Web Stock Data

Natasha — Tue, 09 May 2017 13:49:22 GMT

jamielaird,

First you need to insert a spoiler tag, and then with the cursor inside it insert photos

jamielaird — Tue, 09 May 2017 13:53:37 GMT

Done - thanks so much Natasha :-)

Definitely I learnt something new today! Thanks for this challenge.

I used first the download tool to extract the data and then the text to column, first to split the data by rows and then another to split it by columns. Then I just removed unused fields and used the dynamic rename to pick from the first line of data the column headers. Autofield to give a field type as it was all string. Fun!!

Went above and beyond on this one. Created an app where you can input (probably) any real ticker and it will spit out the data in csv format as well as 2 charts for your viewing pleasure (saved to same folder as the app location). Any feedback on where this can be improved is welcome!

Wow - you turn you back for 1 min, and then @JoeM posts the next challenge while you're not looking, and before you know it there's dozens of bright people who have solved the problem already.

So - summary is that I did much the same as @patrick_digan @BenMoss @MarqueeCrew and @alex 's basic solution.

I gotta say, people really swung for the fence on this one with charts, and graphs etc - I just just used some of the analytical tools (violin plot; histogram and a scatter plot) to see if there are any obvious anomalies (and there are :-))

was impressed by @Joe_Mako 's approach - in retrospect it's obvious, but the trick is seeing it the first time.

I also struggled with the newline use of TextToColumns so did the same workaround as @NicoleJohnson :-) But peeping at the solutions above, now I know this one for the future...

I'd love to take credit for this challenge @SeanAdams, but this week @MattD started his weekly challenge authoring campaign! He's got some good ones planned for you guys over the next few weeks!!!
