Startup Idea: Automated Stock Market Data Tracker and Analyzer

Startup idea to address the difficulty of tracking and analyzing real-time and historical stock market data during office hours. The concept involves creating a user-friendly software that provides valuable financial data analysis while allowing customizing algorithmic calculations and sending automatic notifications when set thresholds are met.

I currently work in Insurance, but as a Software Tester, I have also worked for Finance, Back Office system and hardware. One of the problems I have at work does not directly involve work. I work regular office hours, which makes it hard for me to watch, much less research stock information.

While I can easily get historical price data, it is much harder to track historical option data. I also find it difficult to gather value-based data. For example, historical P/E ratio data costs a huge amount of money.

Since I only do this as a part time, side interest, outside of work, I can't afford the very expensive prices for the data. Yahoo use to have a datafeed that did some of this, but they have since turned it off.

There are lots of good screeners that exist, such as https://www.finviz.com/screener.ashx but none that allow you to take that data locally and play with it or inject your own algorithmic calculations.

I guess to wrap this all together, it's hard to track real time data while at work. Even a automated message saying X now fit your requirements could be useful. While historical data is querable by screeners, it's difficult to access the underlying data. For example, I can filter by P/E ratio, but I can't graph the P/E ratio overtime or compare it to that sectors historical P/E ratios without a ton of manual work.

I had one coworker actually quit his job (he was the head of operations) so he could spend more time working in the stockmarket.

I get much of your context implies B2B problems, but it did not forbid this sort of problem. Tons. I found http://www.vuru.co/analysis/PDLI (example stock) gets at some of the data I want... I also use http://www.dripinvesting.org/tools/tools.asp and https://www.gurufocus.com/fair_value_dcf.php and I hand-coded a script to pull yahoo data, but that script no longer works due to yahoo shutting the service off. I no longer know where to go for the data I want at a reasonable price.

See https://stackoverflow.com/questions/754593/source-of-historical-stock-data for examples of how one might spend several hundred dollars a year to access some basic data.
