Saetta AISaetta AI

Quantitative trading intelligence, recorded before the outcome.

Every US trading day, Saetta AI screens about 887 eligible US-listed stocks with a fixed, rules-based method and seals its top 8 as the overnight list at about 15:40 New York, before the closing auction. It also runs insider-activity alerts from public SEC Form 4 filings. Every list and alert is time-stamped before its outcome is known, and the forward record below keeps every result, losses included.

Recorded before the outcome:every list is sealed and time-stamped before its entry auction and is never changed afterwards.

Losses kept:every session stays in the forward record, losing ones included.

Saetta AI does not hold your money or place trades. Nothing on this site is personal financial advice. Payments are off. Important information.

Every figure on this panel: live shadow session, overnight, pre-market, regular session and after-hours, Tue 6 Oct 2026, 03:59 to 20:00 New York. Measured: live market-data ingest and the sealed journal; scoring was not attached. Not customer-facing. How it is verified.

How this is verified

Every figure above is computed from one sealed evidence folder for this session. Its manifest lists the SHA-256 of each of its 60 files. The site's generator checks every file against the manifest and refuses on any mismatch, missing file or extra file. It then checks the files against each other (the per-minute counts and the channels each add up to the total) and against the session report, and writes the panel's data file. The page adds no number of its own.

Evidence manifest SHA-256: fc2881e94b6f158e2610033090cee3c17b4ae9b9b72363438b1298b4fbb9abb7

The stream stopped cleanly and sealed every journal file. Up to 2 records still in flight after the stop signal were not written; they are not in any figure.

Lag runs from the exchange timestamp on each trade or quote to its receipt in the engine core, including the network path to the core's data centre, and carries the clocks' own small uncertainty. Shadow sessions run on the live market feed and serve no customer.

How Saetta AI works

From daily market data and public filings to a sealed list and a public forward record. The method is proprietary. Full page.

  1. Data:daily prices for US-listed stocks from third-party providers, and public SEC Form 4 filings.Daily inputs
  2. Rank:a fixed, rules-based ranking of the eligible stocks; the top 8 make the list.Fixed rules

Inputs

Inputs: daily US stock prices from third-party data providers and public SEC Form 4 filings from EDGAR. Each list uses only data available when it is sealed. Visitors see our lists and modelled results, never raw vendor data.

Data-driven stock rankings

Each overnight list ranks 8 stocks, 1 to 8, from the eligible US stocks that day. A rank is not a price target, and it does not say what you should do.

Ranks run from 1 to 8 on each overnight list. This strip is the scale, not a live ranking.

How a signal earns its place

Every signal set is tracked forward from its start date.

Each new signal set starts its own forward record on its start date. Records are never back-filled or joined. Machine-learning models have been tested in our research; none is used in anything we publish today.

Forward record

A record that starts on a date and only moves forward. Each session's signals are recorded and time-stamped before the outcome is known, and the modelled result is added once prices are final. Results are modelled, not live trades. Losing sessions, pending rows and sessions where a signal set did not run all stay in the record.

Forward record since 1 October 2026. Latest session: 14 October 2026. Updated 15 October 2026, 01:30 UTC.

12 Oct 2026−US$22.44−US$22.44−US$21.29−US$21.29

A separate modelled account, not broker fills. It starts with US$20,000 at the 12 October 2026 opening auction, buys the same signals, and keeps cash the signals do not need in whole SPY shares, selling SPY when the signals need the money. Modelled IBKR Tiered costs and 2 basis points of slippage on each side apply. The SPY line starts at the same auction. Most of this account can be in SPY, so it can fall with the market. Every completed session stays in, losses included.

How it is modelled: each signal is recorded and time-stamped before its order time and is not changed afterwards. Orders are sized in whole shares for a US$20,000 model account and priced at the data vendor's daily opening and closing prices, after IBKR Tiered commissions with per-order minimums, modelled exchange, clearing and regulatory fees, and 2 basis points of slippage on each side. No order is sent to a broker. A session is added once its prices are final.

Comparison limits: the SPY reference holds the full US$20,000 in SPY from the opening price on 1 October 2026, while the model account starts at that day's closing price and puts only part of its money into each session's signals. Capital used and idle cash differ, so the two lines are not like for like.

The overnight list is bought in the closing auction and sold in the next opening auction. Insider-activity alerts are bought in an opening auction and sold in a later closing auction, which can be in a later session. Alerts that were blocked before entry have no modelled result. The result is in basis points of the money the signals used; a basis point is one hundredth of one percent. Pending rows are not final yet, and rows marked not available stay in the record with their reason. The share above zero and the average use completed dates only; the share is of signal-set results, not of single trades.

These results are modelled from the engine's own signals, after modelled costs. They are hypothetical: not live trades and not a client account. Past performance is not a reliable indicator of future performance.

How these figures were made: recomputed on 30 September 2026 with a stricter test (no look-ahead, costs and trade sizes modelled separately for each starting balance) and independently checked. Every balance shown made less than simply holding SPY over the same years; several had smaller drawdowns.

What this does not promise. No result, no level of accuracy, and no better outcome than the market. The 2017-2025 research backtest, after fees, made less than holding SPY at every supported account size on the home page. Several of those accounts had a smaller worst drop than SPY. The US$500k account had a larger one. No date is promised for anything marked coming soon. A forward record will be short at first. A few weeks of results cannot tell you whether a signal works.

FAQ

Plain answers. Open the FAQ page.

Is this financial advice?

No. Nothing on this site is personal financial advice. Information from Saetta AI is general and does not consider your objectives, financial situation or needs. Saetta AI does not hold an Australian financial services licence and is not registered as an investment adviser in the United States.

Where are the research results?

The home page shows a research backtest of the proprietary overnight ranking, 2017-2025, after fees, next to holding SPY, for each starting balance in the results file. A losing year stays on the chart. Open the results. The label on that block is backtested research results, and they are hypothetical. The home page also shows the forward record, which starts on 1 October 2026. Open the forward record. Past performance is not a reliable indicator of future performance.

Why show a backtest that made less than holding SPY?

Because that is what it showed. SPY is an exchange-traded fund that tracks the S&P 500, an index of large US companies, so holding it is a simple yardstick. Over 2017-2025, after fees, every supported account size on the home page made less than simply holding SPY. Several had a smaller worst drop than SPY. The US$500k account had a larger one. The research accounts were only partly invested, so they are not a like-for-like swap for an index fund. We would rather you see this now than find it later. Past performance is not a reliable indicator of future performance.

What is the difference between the backtest and the forward record?

A backtest applies rules to past data after the fact. The one on the home page covers 2017-2025, after trading fees. It is hypothetical, and it was built by people who already knew what had happened. A forward record starts on a date and only moves forward. From 1 October 2026, each overnight list and insider-activity alert is date-stamped when it is published, before the outcome is known. What happened next is recorded afterwards, by the same rules every time. Both are calculations from published signals. Neither is a client brokerage account. The forward record is on the home page.

When does the forward record start, and what goes in it?

It starts on 1 October 2026. It covers every overnight list and insider-activity alert from that date: losing sessions, pending rows and sessions where a signal set did not run stay in; alerts blocked before entry have no result. Entries are date-stamped when published, and we do not edit or remove them. If a model changes, the new version starts its own record from its own start date. Records are not joined together to make one look longer. A few weeks of results cannot tell you whether a signal works. Do not treat an early stretch, good or bad, as proof.

Will it tell me what to buy or sell?

No. Nothing here is a personal instruction. Saetta AI does not know what you own.

Can it trade for me or hold my money?

No. We are not a broker or a custodian. We never hold your money or investments, open trading accounts, or place, route or execute trades. Any trading decision, and its result, is yours.

Are payments on?

No. There are no prices and no checkout. Do not send money.

How do I create an account?

Open an account in the portal on this site: email, password, country and an authenticator app; no SMS. New accounts are approved by hand during the evaluation, and data access is by invitation. Signed-in accounts can add a passkey, create, name and revoke API keys, and see their own usage.

How is my account protected? Can I use a passkey?

Sign-up needs an email address, a password and an authenticator app. We do not use SMS codes. After you sign up, you can add a passkey, for example one that uses Face ID or Touch ID, and sign in with it. The Security page also lets you replace your recovery codes, see your sign-in history, and sign out everywhere. Passwords are not stored as the password itself. Account data is kept on a server in the Netherlands. We will never ask for your password or an API key by email. We never ask for brokerage logins, because Saetta AI does not connect to your broker.
