What it isn't
Not advice
Signals are my own interpretation, not recommendations to buy, sell or hold.
Not a broker
It only reads market data. It never places trades or holds money.
Not always up to date
Prices may be delayed, incomplete or wrong.
Not enterprise grade
A personal project. Don't reuse a password from anywhere else.
Play with it if you like, but please don't use it to make financial decisions. The terms and disclaimer have the full details.
Why I built it
I come from operations, not engineering. Prism is how I'm learning about market data and about building software with AI coding tools. It's early and changes often; the build log covers what went wrong along the way.
