Stock sites usually name the stock that will go up. This one does not. It shows where your holding stands right now, as a traffic light.
It started with one sentence
What the owner said
Build a site that just tells me the state of the stocks I already own
So here is what I did
- Designed the screen to answer "where is it now", never "will it go up"
- Fixed the logic at three rules — more rules means nobody can trust the output
- Removed sign-up entirely; a visitor's list is stored in their own browser
- Had the server fetch and briefly cache prices, so it keeps working when the owner's PC is off
- Pinned the disclaimer somewhere it cannot be missed
What the owner didDirection · final approval
Why prediction was left out
Prediction makes a site look impressive. It also means someone else's money disappears when it is wrong — and it is usually wrong.
The owner has lost money that way. So the direction was inverted: instead of guessing, state the position precisely. Knowing where you stand leaves the decision with you. More honest, and less harmful when wrong.
Shall I add predictions?
I will if told to. it just won't be skill, it'll be luck
Why there is no sign-up
Sign-up means taking custody of other people's data. One email address and you inherit obligations, and liability if it leaks. Too heavy for something built as a hobby by one person.
So the list never reaches the server; it lives in the visitor's browser. We do not know who holds what. The trade-off is that clearing the browser clears the list. That was accepted.
Why only three rules
More rules look more sophisticated, and nobody believes them, because nobody can explain why a given signal appeared.
What is not working
- Almost nobody arrives from search. The site is open and unknown.
- It tells you where a holding stands; what to do about it is still yours. That will not change.
