looking for software

Python is another name for spaghetti. The world of finance really needed another way to say 1+ 1 = 2.

You can write spaghetti with anything. In reality it's the most productive language. Especially since there's 353485438 packages for anything and many are running C or C+ underneath, making them fast. Its popularity speaks for it.
 
here is (i think) the best free source i could find..

There is a huge difference between learning to be a software engineer vs learning data science.

Data science is pretty easy. I personally hate code and want to write as little as I can. I am interested in results and analysis, not code.

Learning to use pandas in a jupyter notebook is not much harder than using any other software. Trying to find workarounds for trivial data science problems when we already have great data science tools makes no sense.

Just learn the data science tools and be done with it.

True that Pandas can do OP's request easily but there is definitely a learning curve. The basics are easy enough but things can get somewhat complicated quickly.

Spending my time writing a GUI backtester and initially it was relatively easy to get going but when threading and memory issues surface, the time to solve issues goes from hours to days.

RATS i missed that...
sigh

however... if i was clever, i could start updating with another source the day results..
and through the limit it would take me about a month to bring each ticker up to the recorded day results...

or

i am back to using the TD Ameritrade API developer source..

thanks ph1l
at least i had the presence to grab the 13 years of data before i couldn't...
 
i'll do it for $1098 and have it done in a day :sneaky:. to the OP, search for screeners. Not sure if there is any software because this is trivial if you have the data

You trying to put me out of business? All's I want is a living wage that I don't really have to work for. The free market is race to the bottom.... :)
 
Done this already for my own use. Is there any demand from traders/algo traders for a service to deliver a database, screening software, data api support, auto data downloading/updating/logging, dividend/split price adjustments, multi data source support and comparisons etc?? Sorry IAS_LLC / 2rosy you'll have to run faster to get to the bottom ... :sneaky:
 
What are you talking about? i didn't say i would write it (or offer to, or even give my real name to be contacted)... i said he could go to yfinance is on github open source... and confirmed it works so that it wouldnt be a waste of time

maybe leave the policing to the person who runs this great board...
