Start with a narrow objective, not a giant wishlist
Most scanner ideas fail because they try to do too much at once. A good first version defines the watchlist, the exact condition, and how the result will be shown without making the chart unreadable.
What makes a scanner usable
- a fixed symbol list with readable labels
- one consistent rule per scan pass
- clear table or display logic
- state outputs that can be understood quickly under pressure
Where scanners often go wrong
Scanners often become noisy because the condition logic is not stable enough or the output layer tries to show everything at once. Cleaner scans usually win over larger scans.
Frequently asked questions
Can Pine Script scan unlimited symbols?
No. You need to design around TradingView and Pine limits rather than pretending the chart can behave like a full separate screener.
Should a scanner also generate alerts?
Only if the scan states are clear enough to trust. Otherwise the alert layer becomes noise.
