Transparent stock signal research

Understand a stock signal before you trade.

Search any stock to see the model signal, when it was issued, the signal price, and how the price has moved since.

Positive and negative outcomes remain visible so you can research the signal instead of following it blindly.

A clearer way to start

How a stock signal works

Three checks help you understand the model output before deciding whether to research the stock further.

  1. 1

    See the model state

    Buy or sell describes what the rule-based model detected when the signal was issued.

  2. 2

    Check its age

    The timestamp shows when the signal fired, separately from the latest feed check.

  3. 3

    Review the outcome

    Compare signal price with the latest available price. Positive and negative results stay visible.

What you can verify before you act

The evidence and limitations are part of the product, not hidden in fine print.

Method in plain English

See how the rule-based model works

Methodology and data-source pages explain what generates a signal and where the underlying data comes from.

Outcomes stay visible

Review winners and losers

Signal price, latest available price, and return are shown together. Negative outcomes are not removed.

Freshness you can inspect

Separate feed checks from signal time

Every signal retains its issue timestamp, so a recent feed check never makes an older signal look new.

Frequently asked questions

Quick answers to the questions we hear most often.

What is StockInvestor.us?

StockInvestor.us is a free technical-analysis tool that scans thousands of tickers across global exchanges and flags buy and sell signals using indicators such as Bollinger Bands, RSI and moving averages.

How are the buy and sell signals generated?

Signals are produced by an automated engine that evaluates several technical indicators on end-of-day and intraday price data. They are educational, not financial advice — always do your own research before trading.

Which markets and exchanges are covered?

We cover US equities (NASDAQ, NYSE), Oslo Børs, major cryptocurrencies, forex pairs and commodities — 25+ exchanges in total.

How often is data refreshed?

The homepage checks for new quotes and signals once per minute. Every signal keeps its original issue time so you can distinguish a fresh check from a newly generated signal.

Is StockInvestor.us free to use?

Browsing tickers, charts and signals is free. A paid subscription removes ads and unlocks deeper analytics and watchlist tools.

Is this financial advice?
