Site Modifications + Code Changelogs

If you frequent my site, you'll notice that I update it and the projects I create quite a bit.  Due to size and scope, updates are scattered all around.  This listing serves as a quick reference for those who only want to look at the newest changes.  By default, the latest 15 updates are listed below (with links to the changed or added content). If you are looking for a specific area of the site, use the search field above or use the site nav links in the top right and bottom right of the page. Area specific links are typically on the left side

  2026.07.08 @ 17.50.35

 

  [ /sean/code/cats ] :: (cats.php) v4.17-claude. Ran cats.php thru Claude Code and it addressed a number of issues that are outlined in the script itself. New file is posted in here or by clicking on the source icon in the Cats area.  [ edit ]
    
 
 

 
  2026.07.08 @ 13.38.17

 

  [ /sean/datasets ] :: (tickers.py, pricehistory.py, ma200.py, trends.py, YoY_pct.py) Moved weekday run times to start at 1:10 pm PDT (10 minutes after market close) for pricehistory dataset updates followed by a 30 minute window for all cronjobs that require that data.  [ edit ]
    
 
 

 
  2026.07.07 @ 23.15.38

 

  [ /sean/datasets/ma200.html ] :: (ma200.py) Added 200d+ which totals the number of positive return days a ticker has had in the past 200 trade days. Also added icons to the right of each ticker that links out to Yahoo Finance and MarketWatch for the ticker it is next to.  [ edit ]
    
 
 

 
  2026.07.07 @ 17.50.35

 

  [ /sean/code/cats ] :: (cats.php) Multiple search terms were being treated as AND conditions without '+' operator. Non-operator prefaced term searches are now OR based. 'foo bar' (foo OR bar) vs 'foo +bar (foo AND bar)  [ edit ]
    
 
 

 
  2026.07.07 @ 17.02.14

 

  [ /sean/datasets ] :: (tickers.py) Replaced all periods '.' in ticker names to dashes '-' as yFinance does not support periods in tickers. Example: BRK.A -> BRK-A. Beefed up detect_split() to trigger price history refresh if a split is detected mathematically via ratios and corporate announcement via yf.Ticker(ticker).splits. Script will refresh full histories on some tickers with large (+/-33%) 1 day moves. Example: CRNX had a 98% price jump (no split) on July 7, 2026. Script detects and logs it as such:

[SPLIT] Price jump detected for CRNX: 1:2 reverse split (estimated) on 2026-07-07
[SPLIT] CRNX — 1:2 reverse split (estimated) on 2026-07-07
[SPLIT] Refreshing full history for CRNX

In the event of a corporate announcement:

[SPLIT] Corporate action detected for CRWD: 4:1 forward split on 2026-07-02
[SPLIT] CRWD - 4:1 forward split on 2026-07-02
[SPLIT] Refreshing full history for CRWD

I'm using a 7 day window as yFinance doesn't update prices the day of or the day after a split thereby massive moving tickers will age out of the validation window in that timeframe.  [ edit ]

    
 
 

 
  2026.07.01 @ 21.33.41

 

  [ /sean/datasets ] :: (ma200.py, YoY_pct.py) Added a 'sector-> subsector' popup that displays next to the mouse pointer when hovering over a ticker row. Search field now allows for ticker, sector, and subsector searching.  [ edit ]
    
 
 

 
  2026.07.01 @ 20.44.33

 

  [ /sean/datasets ] :: (tickers.py, pricehistory.py, ma200.py, trends.py, YoY_pct.py) Moved update run time to 3 pm PDT for all cron jobs. If I find that yFinance is posting a complete set of price data sooner after market close, I'll move the update time closer to 1 pm PDT.  [ edit ]
    
 
 

 
  2026.07.01 @ 20.41.52

 

  [ /sean/datasets/YoY_pct.html ] :: (YoY_pct.py) Script no longer generates .txt or .csv files natively. I've switched to a html dashboard layout with on-page column sorting, my portfolio filtering, and the ability to export to csv. This page gets updated every weekday at 5pm PDT.  [ edit ]
    
 
 

 
  2026.06.30 @ 23.46.45

 

  [ /sean/datasets/ma200.html ] :: (ma200.py) Script no longer generates .txt or .csv files natively. I've switched to a html dashboard layout with on-page column sorting, my portfolio filtering, and the ability to export to csv. Added a ranking column goes off highest MA200% and a 1w% column that can be sorted to reorder those tickers that are experiencing a growth spurt. This page gets updated every weekday at 5pm PDT.  [ edit ]
    
 
 

 
  2026.06.29 @ 21.53.08

 

  [ /sean/datasets/trends.html ] :: (trends.py) Clicking on sectors and subsectors titles will list all the tickers in that group. Data links are included at the top of the report.  [ edit ]
    
 
 

 
  2026.06.28 @ 23.13.01

 

  [ /sean/code/cats ] :: (update.php, files.php, caption.php) These plugins have been updated. Use the Source link in the navbar to download the new plugins. No site modifications are needed, simply replace your existing plugins with these.  [ edit ]
    
 
 

 
  2026.06.28 @ 21.35.05

 

  [ /sean/code/cats ] :: (cats.php) Rewrite of search_and_sort() function to be more robust and handle multiple fields (primary, secondary, ...) when defining [order].  [ edit ]
    
 
 

 
  2026.06.28 @ 21.31.26

 

  [ /sean/datasets/trends.html ] :: (trends.py) Created a sector and subsector trends dashboard that updates daily at 5pm PDT. Includes top sector and subsector movers for the day, the week, and the month. Subsector tables breakout even more: 1d%, 2d%, 3d%, 4d%, 5d%, 1m%, 2m%, 3m%, 6m%, 200d%. It is generated off 2 files I create and maintain in /sean/datasets:
  • tickers.csv - master ticker,sector,subsector file
  • pricehistory_365.txt - ticker historical prices for the past 365 days

The dashboard data is updated every weekday at 5pm PDT (as I don't have paid access to live data).  [ edit ]

    
 
 

 
  2026.06.28 @ 20.42.26

 

  [ /sean/code/cats/files/plugins ] :: (csv.php) Created a CSV file importer. Plugin can be viewed in the plugins folder link. Here is a raw output sample page pulling in the latest '/sean/datasets/YoY_pct_10y.csv' file (~3000 records). Here is a link to the same file showing only those tickers with a positive gains Streak >=5 years sorted by Streak,AVG% (overall 10y) in desc order (~100 records).  [ edit ]
    
 
 

 
  2026.06.25 @ 23.40.59

 

  [ /sean/datasets ] :: (tickers.csv) Removed CWAN as it went private.  [ edit ]
