Next signal scan 22:10 UTC ·
A strong stock pulls back. It turns back up. That's the signal.
Signal desk is a free public StochRSI screen for US and Brazilian equities, built and run by one person, that publishes every signal it fires, including the losing ones. For people who own stocks and have a day job. Signal desk waits out the dip and emails you the day momentum turns back up.

How a signal works
Nobody can watch every chart every day.
Three conditions, in order, and no opinions in between.
-
01
Momentum hits its ceiling
On the monthly or annual chart, momentum reaches the very top of its range (StochRSI K and D both at 100). That is rare, and it usually means a serious uptrend, so the stock joins the desk.
-
02
The pullback arrives
On the daily chart, momentum falls to the bottom of its range (daily K at 20 or below). The long term trend has not broken, so the stock is armed and waiting.
-
03
It turns back up
Daily momentum crosses back above the line (K over 20). The dip is done, the trend is intact, and a signal fires. Founding members get it by email the moment the scan completes.
The email
This is the product.
The desk's first signal: GATX, fired at the Jul 6, 2026 scan. This is the email that goes out.

Quality filters: cleared both when this signal fired.
The record
Every signal, counted, whether it worked or not. Not a track record yet. It is the start of one, in public: every signal stays on the board, including the ones that go wrong.
Every percentage here is the price change from the day of the signal to today. Nobody bought or sold anything, and there are no fees in between.
The quality filters
A hot chart is not enough.
Two filters on the business itself have to agree with the chart before a stock is allowed on the desk.
Growth in the forecast
Analysts have to expect earnings to grow at least 10% a year. A stock that is only going up on momentum does not qualify.
Big money buying in
The three largest investors in the world, BlackRock, Vanguard and State Street, have to be adding to their positions in their latest public filings, not cutting them.
If the data cannot be checked, the stock does not get in. Not flagged, not admitted with an asterisk. Where there is doubt, the answer is no.
I'm a product designer, not an analyst. That is the point: I built a machine because I did not trust my own timing, and the machine has no opinions. The rules are published, the scans run whether I am watching or not, and the losers stay on the board.
